Thanks for watching Super Nerds! *Here's a a link to last week's video* if you haven't peeped it yet: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-f4QhfwpvdrI.html -- kH
If you look more blue the faster you go and Dr. Manhattan controls time, wouldn't he he always always be blue shifted? Hes the only object in the univers that never actually stops moving, thus hes always faster then the rest of matter
Be glad Dr Manhattan isn't using Curium to ionize the air around him. He would be a cool purple color but anyone near him would have their faces melted off. Curium is a synthetic element made from plutonium, it produces the very unstable isotopes 242 and 244 which emits very intense radiation, so dangerous it is rarely used at all except in very safe environments like space. The mars rovers had the isotopes in their x-ray spectrometers. Curium in produced unintentionally in atomic reactors.
I love the history of the demon core. there is so much more to it than most people know. If i were a superstitious man i would say it was cursed. So please do the episode about it, truly amazing stuff. Because Science. Best. Show Ever!
4:24 What about Al in Quantum Leap? He travels backwards through time, but only as a hologram. Essentially, he's not going anywhere, but the chamber around is projecting the past around him...kinda like a holodeck. Since he's only viewing the past & not interacting with it (aside from when he communicates with Sam, wouldn't that be a feasible method of pseudo-reverse-time-travel?
Yeah, there's plenty of blue-glowing things that aren't harmful like argon signs, glow sticks, and LED's. Nuclear reactors and Cesium isotopes are the main blue things to avoid.
@@vincentxu8217 I guess if you want to be pedantic, argon signs also don't glow without electric current either. Glow sticks don't glow forever and I didn't mention that either. I can only say so much in a comment without it becoming cluttered. It can be assumed that I meant the LED was powered.
As someone who has tried the Naruto run and subsequently eaten shit by putting too much mass too far forward, I am very excited to see this potentially happen to an Olympic sprinter. That probably sounds worse than it is.
Using my vast knowledge of physics I have deduced that everything stated so far is incorrect. According to my studies, Dr Manhattan is actually a mutated Smurf who moisturizes well to get his magnificent glowing skin. Much like Kyle's hair.
On that opening bit: I've always found that "store waste in barrel in a hole where it MAY someday break open causing a localised disaster" is a lot better than "spew waste directly into the atmosphere from a chimney where it GUARANTEED causes a worldwide disaster". It's so weird that people are so up in arms against nuclear power.
Well recently there are power plants being created right now by bill gates that can actual use the already huge stock pile of depleted uranium we have just chilling around the US. Look up Terra power reactors if your interested.
@@sobrukai4056 are you talking about some kind of scaled up RTG? EDIT: Looked it up. It's an automated breeder! Can't wait to see how they pull it off, and I would gladly invest in it if I could!
It's a holdover from the cold war. Fossil fuels are destroying our world, and renewables just won't cut it, at least not in time. Conventional nuclear power and potentially fusion someday are the only conceivable, technologically feasible ways to save ourselves. I just hope everyone sees that in time...
I love how Kyle always shows how much he cares about our safety, from maintaining to getting flu shots. Thank you Kyle, I'm going to go get my flu shot!
RE: Dr. Manhattan Cherenkov radiation: But he body tho. Made of mostly water. Reactions happening under his skin cause Cherenkov radiation. Also coincides with the "leaking Electrons" quote. Also, why not both?
@@T-verseTrevor The Plutonium Core that Kyle mentioned in the video. It was involved in two separate incidents during the Manhattan Project that caused the deaths of a number of people due to radiation poisoning. After the incidents, it was referred to as the Demon Core because of the fatalities.
I got my flu shot last week! 💉 I resisted getting them for years because i thought they gave me the flu, but I was convinced to go get it this year thanks in large part to science educators on RU-vid. Understanding the science behind the flu and the flu shot makes a difference. Also, I got the flu last year and it was the _worst_
Congratulations on your choice, Elliot! We're all thankful for your collaboration for a healthier world! Thanks to you, both you yourself and those around you are a lot safer now!
Regardless of where you live, thank you. I can't get a flu shot because I have an autoimmune disease and have to take immunosuppressants to be able to walk, which make me more susceptible to the flu, among other things. Anti-vaxxers scare the crap out of me because people like me die every year because someone refused to have their child get their measles vaccine or whatever and they got too close to someone with immune problems. I'm not trying to turn this into an anti-vaxxer roast. They're not evil or particularly stupid, they're just uneducated, scared, and are listening to *really* bad advice from the internet that hurts themselves, their children, and everyone around them. Education is key.
Technically they DO give you the flu virus, just a weakened strain. So when the real stuff hits you're already immune. But if your immune system is weak you can catch the flu but due to being weakened it'll pass pretty quickly.
Flu shots are like the least important you can get arent they. The flu is unpleasent of course but it will most likely not kill you as long as you are in an otherwise healthy condition. Additionally the flu mutates so quickly that by the time you get your shot it might not even really do anything anymore. You just took an unnecessary risk, as injecting anything into your system always comes with a risk, that is worth taking with most other vaccines that are not against the flu.
Hey Kyle! Loved the Dr. Manhattan show! The part that peaked my interest was Dr. Manhattan quantum tunneling to Mars For a while now I've had this theory about a Cyclical Big Bang, where after the heat death of our universe and some unimaginably long period of time, say 2 googleplex years as a ballpark estimate, every particle in existence manages to quantum tunnel to a single point in the universe despite the infinitely small probability of it This becomes the next big bang and the cycle starts again, do you think if given enough time, monkeys and typewriters style, that this could happen? Also this leads to questions like, what if our big bang wasn't 100% of the universe but just a fraction? Could that solve the matter/antimatter big bang mystery? Are there other Big Bangs quintillions of light years away? In an infinite void of multiple big bangs has a universe ever restarted inside an already existing one? Could the opposite happen? Could every particle quantum tunnel away to different areas of space and thus our universe suddenly vanishes? What if only half of all particles did this? Granted the odds of those events happening during our time might be 13 billion out of 2 googleplex If the universe is cyclical then is there no beginning and it has just always existed? Because if something doesn't exist then it can't come into existence without the parts needed to bring it into existence having already existed Going too deep into the philosophical domain now Long Live Because Science! Your fellow sciencey communicator guy just without a youtube channel
Hey Kyle, love the show. Finally worked up the courage to start commenting. I think teleportation and memory loss is totally okay and wouldn't even need to have the accuracy of a Star Trek teleporter. Since Manhattan is experiencing both the past, present, and future simultaneously he still retains all of his memories or is able to still access them.
Kyle, i work in nuclear power in the US (mech engineer in nuclear maintenance research) and i wanted to thank you for the nuclear power plug! It is very safe and it is our priority in all things we do to consider the safety of the public. Stay awesome and thanks for making science accessible to all! Folks like you and The Mythbusters are making science, math and engineering fun!
@@eddiephoenix9698 Interesting. I stand corrected. I didn't know Laplace also had a demon too. As for Maxwell, his demon was part of a thought experiment which could seemingly violate the second law of Thermodynamics. The experiment had consisted of a box with a small gate in between which could be opened by the demon to make particles pass through it. The demon had information about position, momentum,etc about all the particles in the box.
A question about the cherenkov radiation, since he's blue and not exactly fleshy could HE be the medium the particles are moving through faster than light is in the medium of himself? Or... Second possible explanation, could the way he affects time be affecting the particles in some way?
Hey nice vids as always Have you considered doing a video about the theory that uses the professor on Futurama, about the ship engine doesn't move the ship but the space around it?? Great job and good luck
Functionally the same concept of an Alcubierre drive. By compressing the space in front of you and expanding the space behind you, you create a pocket of space-time that moves (at potentially superluminal speeds, there is no limit on how fast the universe itself can move) while the ship remains basically motionless with respect to local space-time. To bring the energies required down to halfway achievable levels you need exotic matter, and if you use it to go more than C you will have to figure out a way to deal with the Hawking radiation generated. It is, however, possible in theory.
I would imagine that there might be some sort of aerodynamic effect for anime running but I can't imagine that this would surpass the balancing and physiological advantages traditional arm pumping give.
it's better for a full out sprint, but you need to be perfectly balanced to pull it off. It even was in a couple ninjutsu manuals, but was later phased out due to balance issues.
As for the time travel feasibility bit: As far as I remember, there are some possible methods of backwards timetravel within our currently known laws of physics but all of them require infinite amounts of energy, exotic matter, negative energy densities, etc. (basically stuff that is mathematically possible but practically impossible)
I listened to an hour long talk about time travel paradoxes, I wish I could remember the guy's name, he's fairly famous and I'd recognize it if I heard it, but he went through every plausible thing we've been able to come up with and demonstrated both logically and mathematically that in every single situation to get around the speed of light, you'd need to use so much energy that you create a black hole. Whether it's cosmic strings, Alcubierre drives, or whatever, you can't concentrate the necessary energy in one spot without distorting spacetime into a black hole. It seems that black holes are nature's way of avoiding time travel paradoxes.
@@ryanmarbut1035 Sean Carroll! That's the scientist's name I couldn't think of. I guess I had to let it stew in my subconscious and your comment ripped it out of my head. The lecture I mentioned is an hour long and from 2010. Just google his name and the phrase "time travel" and you should find it, if you're interested.
I would love to see a full-length video on the Demon Core. You have told (slightly) different stories of what really happened, and I would love to see a legitimate story on it. Love the show dude!
Hey Kyle, that was a fine Riker Manoeuvre! Why is it that at the end of your main show, you always have a part at the end where you look to the side of the camera? Always wondered.
I got a flu shot like 2 hours ago and feel unreasonably validated now because Kyle said it's a good idea. Also: Teleporting! I'm of the mind that it would not be you (in the sense that the question is usually posed) on the other side. However, I think the teleporter example is actually a good analog to discuss a related question: do you ever maintain you? Every moment of every day you experience things, you move around, reactions are taking place, etc. etc. and the only thing that really remains consistent on a core level is that all your bits traversed the distance between where you were and where you are. I posit that you are _constantly_ becoming a new entity, and it just happens that the newest version has some information collected from the previous versions (memory), giving an illusion of continuity. I think the "teleporter kills you and makes a copy that isn't you" idea requires a) that there is something "else" consistent throughout your life and you're not being reinvented every time you have a thought or feel something or just, like, exist for an amount of time and b) that whatever this thing is, it would be somehow immune to being duplicated elsewhere. Since we have yet to find anything other than the same matter and energy we've always seen inside us, I'm tentatively going to suggest there isn't anything like that at all, but if there is and it is discovered in the future it stands to reason that a core function of any teleporter would be to also replicate that "thing". So even if something like a continuous consciousness exists in a way somewhat independent of our bodies, I don't think there's any good reason to expect that this "thing" can for some reason not also be de-/reconstructed, as that would make it unique to pretty much anything that's ever been observed (so far, of course).
@@wcookiv To say rorsachach was a bag guy misses the whole point of the charcter. I think it is safe to say that through out his life there were many people who he saved that thought of him as a hero. And night owl certainly thought of him as a friend. Rorschach point was to illustrate what would happen if some one would have a very strict moral code of what was good and what was bad, and was not able to comprise or change their beleifs. Saying that, I think Rorshach is the most interesting character.
The only valid use of a teleporter, assuming Enterprise D or better computers, is to repair genetic defects and rebuild you telomeres. Technically assisted immortality, and it's canon, based on both an episode of the Star Trek animated series, and the episode of Next Generation where they repaired Dr. Pulaski who was being unnaturally aged by an aggressive virus.
"We talk a lot about nuclear power and nuclear physics and nuclear material melting your skin off. . . " Me: "But we have yet to talk about the guy who's DNA got melted!!"
Manhattan doesn’t need memories because he is simultaneously experiencing every moment of his life from birth to “death” (even though he couldn’t see further than the Nuclear war as “my future is clouded past that point”). Haven’t seen the film in 6 years but I remember him saying something like that. Essentially, if you broke your leg, you don’t need a memory of breaking it 20 years ago to know you’re in pain right now. And his “right now” also happens to be every point in his life. As he is pretty much extradimensional, he sees time the way we see a building - not brick by brick, but by its totality.
@@chroni3659 I literally grabbed the GN for this. "Everything is preordained. Even my responses." "I'm just a puppet who can see the strings." Basically, "In 32 seconds I am shocked to realise I pooped myself."
@@chroni3659 No. Even if he knows what's going to happen he still has to do it. In this case he wasn't supposed to have that realization until that moment. Once the moment comes, he goes through the motions.
Hey Kyle, could you do a hair maintenance guide video? We'd all really appreciate it, and you could just refer people to that video when people asked for advice in the future.
@@meganofsherwood3665 true, but it seemed the assertion was that the accident which gave us two rikers occurred on the enterprise. It didn't. That was my point.
Yes to Demon Core video. I've already watched a lot of videos on the same, because I really find it fascinating as well. But, I'd love a Because science video on the same topic. I love you low budget Thor.
From what I remember in college, arms moving while running act as a pump to help air move more quickly in and out of the lungs thus increasing oxygen levels in the blood. Running with your arms behind you would likely act against that and hamper your ability to quickly exchange gases. They also swing opposite of your legs, an example is when your right leg is forward your left arm is forward. This is to help maintain balance when running which is more unstable that walking. The Naruto run is likely an unstable type or run more prone to falling at higher speeds.
Its a universe where a sexually advanced race of bald ppl have to take an oath of celibacy so they don't kill the sexually immature with super sex. I'm sure a transporter should be fairly safe. By the by, Kirk and Lt. Saavik were conversing during a transport. ...how
Sherbet rant had me dying..love the show Kyle. "Mane-tain" now needs to be a show. I don't have hair much but I feel the show would be interesting and beneficial.
Kyle your explanation about how if teleportation is mapping a person's molecules while breaking them down is the same as how the stargate system work. It was also used in an interesting way in Doctor Who with Peter Capaldi. He had used a teleporter to keep making copies from the original mapping of his person.
As one of the immune-compromised people out there, thank you for getting your flu shot, Kyle! I've been sick since September with a sinusitis that won't go away. Oh, I also have a crap ton of allergies that prevent me from getting most vaccines. But I took the risk to get my Tetanus shot when I cut my foot on a rock. I was medically monitored for almost an hour afterwards to make sure I'd be ok.
Just realized that Heizenberg’s uncertainty principle is one hell of a kink in teleportation plans involving scanning and recreating an exact replica in an alternate location lol
Conjunctions don't need extra energy to perform their function. Wind powered _boats_ existed before the steam engine, they are called sailboats. And you could in theory have electronics run off of batteries that are recharged with photovoltaic arrays, but best hope for sunny skies.
Here’s a fun thing regarding teleportation and the ship of Theseus. A person is really just the sum of their memories. Sure there are some structural and chemical aspects to the brain that are very important, but most of the aspects that a person would be likely to consider fundamental to them, what makes them unique, are determined by the sum of their experiences. Now for the ‘fun’ part. When you go to sleep, your continuum of consciousness ends. While it lies dormant, your brain does housecleaning and upgrades, integrating new experiences, moving memories into deeper storage, and exploring, forming and reinforcing connections through REM sleep. When it’s done, the sum of your experiences has changed, ever so slightly. The you that wakes up in the morning is not the same you that went to sleep, in the sense of what really makes you you. In a very real sense, every night ‘you’ die, and every morning ‘you’ are born, and each of us only lives for one day, or however long that waking cycle happens to be. Sleep tight. ;) P.S. Barclay was right, I don’t want to wake up in the (Prestige) box, I’m never volunteering for teleportation.
HELL YES!!! GIVE US THE DEMON CORE, O DARK LORD KYLE! On the real, I am fascinated by that story and you do a great job with the show!!! Keep up the good work!
Fun Fact about nuclear waste from a Geologist: Waste is sometimes (all the times?) stored in underground salt formations because salt has an essentially unmeasurable permeability (for all those toxic material bois) as well as fairly good thermal conductivity to allow the heat to dissipate into the ground. They also dig out giant tunnels around the waste and repack them with salt gravel because over time (appx 10,000 to 100,000 years) the salt will reform tightly around the waste because it flows.
And we could GREATLY reduce the amount of that waste by reprocessing the spent fuel, or using same in a breeder reactor, or both....but nah, let's not. Thanks Carter :(
4:29 there are two problems with determinism 1) Heisenberg uncertainty principle principle means that you cannot know all the information to begin with. 2) On the quantum level some things (such as if an atom with decay) cannot be determined, therefore even though causality is maintained determinism is not. If you take this to the fullest it means that simply rewinding time would alter the future because things will be different in the quantum level and over time will cause noticable changes on the macro level.
The idea of whether or not you are still you when you are teleported can also apply to much simpler things in a way. Like when you wake up, all you have of the past are your memories. How can you be sure that you are the same you that went to sleep the night before? Or even how do you know you are the you from 5 minutes ago and not a being that was just created right now with implanted memories of "your" past?
Yes I would LOVE an episode about the Demon Core. Also, something you might add to that episode is the December 30th 1958 Los Alamos incident involving Cecil Kelley...morbid as the subject matter may be. One suggestion on the "blue glow" conundrum. Perhaps Dr. Manhattan is...translucent to a point and the blue glow is from the Cherenkov radiation being produced as near lightspeed nuclear byproducts are passing through his body, generating the visible blue wavelength photons, but as his body acts as the shielding [he effectively the swimming pool for the reactor] nobody is getting a dose of harmful radiation. After all, the human body is MOSTLY water...
so the teleporter that logs the position, momentum, and energy of every particle in your body is basically making a save file of your body and transferring it elsewhere. therefore if you saved this "file" you could theoretically reconstruct yourself in the past at any of the previous "saved" positions. if you scanned your brain than inserted that "code" into the younger body, you would be younger but still have your memories.
i notice how in fiction, characters with abilities using science to explain and adding real world logic they end up being way more powerful than it was before and that they might have more abilities to that than originally thought. But the person who created the character don't go too far in there powers so they can make a plot so it won't just end a show in seconds
Another idea about "teleportation"is something I read about in the Necroscope Series by Brian Lumely..Stepping out of this dimension, and simply stepping back in to this one in another location.
I SUGGESTED THE NEXT EPISODE! Man, that feels good. Speaking of Naruto, though, I have another question about something that happens in the franchise that could make another great episode: What would happen to the real world if our moon was split in half like it was in the show? How devastating for the planet would an event like that be, if at all? Keep up the good work, Kyle.
A tip from a dude growing out his hair: always brush your hair before you blow-dry it. Go ahead and towel dry your hair, but make sure to brush it before you blow it out. It reduces tangles by a shocking degree. Also, try to find a blow-out spray. It doesn't have to be particularly expensive, and you'll probably want one of the "light weight" ones, as they'll have less oils in them that can make your hair feel gross by the end of the day. But if you spray some on before you brush your hair, then it'll make the brushing easier and improve both the appearance and texture of your hair after blow-drying it. Also, pick a day each month where you're okay with your hair looking super gross and use a hair mask or oil treatment on it. These don't really rebuild the keratin like some companies claim. That isn't how hair works. Hair is all dead cells. What it can do for you, however, is help to hydrate the keratin and smooth out the sheath of the hair. Easy example, hold onto a strand of hair and pinch it between the fingers of your other hand. Try to run it up the shaft of the hair, then down the other direction. Hair has a distinct directionality because of how the keratin sheath forms. Keeping your hair properly hydrated can help this sheath to lay flatter to itself and feel more like a snake's scales rather than a shark's scales. Flat ironing your hair can have a similar, but very temporary effect, but it tends to make matters worse once you go to wash it again. TL;DR: wash your hair regularly with decent shampoo, use blow-out spray, brush your hair, blow dry, look fabulous.
Hi Kyle! Three things. First, PLEASE do an episode on the Demon Core. Fascinating subject I've casually studied for years. Second, regarding Dr. Manhatten's memory, it wouldn't matter if he retains his memory or not. Because of the way he experiences time, ie, every moment simultaneously, and if he doesn't remember his past, he would simply re-experience it post-accident. Memory is not neccessary for him. Last, I'd always thought that the blue came from Cherenkov radiation caused by particles passing through the water in his body. Watch ya Thursday!
Kirk was the one who got divided into good and evil selves by transporter accident. Riker just basically got unknowingly cloned and (again unknowingly) left the copy behind with all his memories, thinking he was the only Will Riker.
Hey Kyle! Long time watcher. Love you content! So check this out little peace of information out. Dr. Manhattan does actually state exactly how he teleports in the Before Watchmen comic. He tells Ozymandias that "I move space around me so that I don't move, space moves".
Think of the math involved with traveling ‘back’ in time like Marty McFly. The idea that the car is going to be in the EXACT spot, years and years after the earth has rotated and tilted thousands of times while traveling around the sun as well as through space. The idea that you could get that math so exact as to do that is so absurd it makes me enjoy the movies a lot more.
Dude, I think I love your videos more and more every time. Could you make a video where you explain more about the philosophy and science behind "you being you"? Like, when the doctor reassembles every piece of his body, or if you made an exact copy of yourself on an atomic or smaller scale, would that still be you? That subject fascinates me. Thanks for the mane-tain tips, tho.
