Neil is still avoiding the latest evidence UFOs released by the DoD Pentagon and US Navy with scores of military professionals testimonies of " Out of this world " performance that defies the laws of Physics. Time to address his comment of No evidence of Alien contact. REPLY
@@spookyninja4098 UFO means UNIDENTIFIED flying objects. Unidentified doesn't mean alien, it means something that has yet to be identified. Therefore there's still not proof of aliens, there's eyewitness statements of something that didn't make sense to them. That's... Not proof.
@@EvolveOutdoors It's never been something from nothing. Everything was always there, matter can neither be created nor destroyed, only change form...it was just all contained within the size of a pea and then rapidly and exponentially expanded.
I love how the talk about bending the universe never comes up in these talks. Folding a sheet is one thing, folding an entire universe feels like it’s a whole other story. Would love to hear you talk more about that @StarTalk
@@megalodon1726 yes but it seems that it would create massive gravity waves in the space time fabric. That could potentially create far reaching consequences but that's another story.
As human beings we always want to venture into the new frontier but basically we have to accept that interstellar travel is an impossibility unless there is a breakthrough in Astro physics understanding and engineering at the same time
Speaking of Space Obama, Star Trek: Deep Space 9, which was probably the best part of the entire Star Trek franchise, had a story that hinged on the discovery of a stable wormhole. (Space Obama is a silly recent nickname for the show's lead, played by Avery Brooks.)
Love wormhole talk! I bought “astrophysics for people in a hurry” (his book), and he touches on that, and it’s so dang interesting. If you haven’t read his book you definitely should. You have to reread it to even capture everything he’s saying in it. There’s so much information. It’s great. I highly recommend it if you’re a space nerd. 😂👌🏼
even better than reading it, is listening to neil read it! i know he has released an audiobook version because it keeps popping up on me as i am trying to get to sleep and autoplay turns it on
Tyson: I want to walk through a wormhole and appear on the other side. Lists Back to the Future, Contact, Bill and Ted.. Star Gate: Am I a joke to you.
@Link of Hyrule NO HE'S TALKING ABOUT A THEORETICAL CONCEPT AND IMAGINARY CONCEPT A THEATRICAL CONCEPT NOTHING MORE......YOU THINK THERE'S MORE BUT THERE'S NOTHING MORE IT'S LITERALLY DUNGEONS AND DRAGONS
@@astrophiledevansh898 Have you had that profile pic for years? I've seen someone with that profile picture (I think. It looks VERY familiar) a year or 2 ago... maybe it's someone else with the same profile pic or similar one, or it was you. 🤔
I have to say this educational format of people just chatting is so much more entertaining and engaging to watch than a person reading a script on their own with some fancy animations along with it.
On my way home tonight I was listening ti an older Cosmic Query and one of the questions was about black holes possibly being connected to each other via worm holes...I thought to myself "later this evening I need to remember to look up what wormholes really are." Was just about to look it up now when this episode popped up in my notifications. Neil has finally perfected mind reading!!
I don’t understand where all the dislikes come from. These guys are just as great of entertainments as they are educators of their desired topics. I personally think they are great for the younger generation.
Love from India. I love these talks,i also want to become just like neil sir,side by side him.He is the man.My man You are also the reason why i am headed towards making a future in cosmology.People dont get this in India,they are like get an engg. degree and a job thats it but im like then whats the diff. in me and others.I want to be different not abnormal.
There's an easier way to explain the relationship between the fabric of space and gravity. I always describe it like this: "Gravity tells space how to curve and space tells gravity how to move."
I’ve recently been listening to Neil Degrasse Tyson, and I must say he is absolutely fascinating to listen to, and it allows me to develop a further interest in science!❤
Chuck, you are such a great guy, a big and important part of the show. Wish you nothing but the best. By the way, that wormhole you created looks nice.
Loved Neil name-dropping Time Bandits! One of my favourite films of all time, which doesn't get nearly enough love. I mean, it has Sean Connery as Agamemnon, John Cleese as Robin Hood, and Sir Ian Holm as Napoleon; what's not to love? 😄
Actually, in "Back to the Future," not only did they fail to factor in the orbit of the Earth, but they also failed to factor in the Sun's movement through the galaxy and the galaxy's movement through the Universe
Or Doc Brown programmed the calculations into the electronics and he just made the default behavior that you want to end up in the same place relative to the Earth.
MIND TWIST: Imagine this video was uploaded 145 years ago, and people at that time are able to look back and marvel at the mindset of people back in 2020, same as we do for people back in 1820, or 1920. Assuming RU-vid is not only a video upload service, but a veritable treasure trove of history and comments from people in the future. Case in point: Not long ago, the speed of sound was considered unbreakable and could perhaps make a person's blood boil.
In a way, kinda. The theory is that when you cross the event horizon, they invert into each other, so time becomes space and space becomes time. That's why once you enter it, you inevitably end up going to the singularity, because the center of the black hole has now literally become the future. How wacky is that?
@@animistchannel2983 that's more or less a roundabout way of explaining that the light arrow = the time arrow, and since all light must go towards the singularity, then all time goes towards the singularity in truth, a 'singularity' is simply a point in relativistic physics where the mathematics breaks down, and can no longer be used. It doesn't imply it is an absolute object or the effects of it; in fact, the event horizon is not actually that interesting. it's just the threshold of no return, much like how every gravitational object has such a horizon for a velocity = 0 object. to make any real predictions of the effects of a singularity requires a theory of quantum gravity, of which we do not have one.
@@felicityc Well, we pretty much know what the 2 options are for encountering the singularity, we just don't know which one will happen. Unfortunately, no one is ever coming back from there to tell us what it was, either way :)
lol i love how chuck breaks the thing in half part way through the episode and then swiftly gets it taped back together with scotch tape by the end. go glowforge!
Oh and Chuck, you do not give yourself enough credit. You're very intelligent and your close friends with Neil. Neil is like Gen knowledge random smart. That is hard to hang with and you do it wonderfully.
Neil, thanks for your explanation of how wormhole works. It is always a privilege for me to watch and listen to star talk. This time I want to point out that I am thoroughly fascinated by creativity and innovation skills of Chuck. He is a great motivator and Star talker you could ever imagine! Good on you guys! 👍
Wormholes are intriguing potential shortcuts through the cosmos, theoretically connecting distant regions of space and time. They hinge on the concept that gravity is the curvature of spacetime, as described by Einstein's theory of General Relativity. This curvature shapes how objects move and interact in the universe. Could our understanding of gravity and spacetime eventually allow us to harness wormholes for interstellar travel?
Wow. Just watched this video, and noted Mr. Tyson mention that with sci-fi time travel, people don't take into account the fact the earth has moved on, so they'd appear in empty space. So glad to hear this from Mr. Tyson, as I wrote a sci-fi screenplay in the 1990's that noted this as 'fact,' and the reason time travel hasn't been successful, until the time traveler in the story figured out a way around it to make it work. Thanks for reinforcing my time travel sci-fi screenplay with some actual 'fact!'
Chuck: “I invented a time machine!” Neil: “Great! Lets fire it up!” *chuck presses time travel button* Neil: “This thing travels through space too right?” Chuck: “What…?” *scene ends with our lovable duo floating in the dead of space*
I think wormholes would be more realistic than travelling at light speed or even teleportation.. and the whitehole thing got me thinking where does it’s matter and energy come from if in fact they do exist
Neil, you need to change that Back to the Future reference, because the Sun also goes around Sagittarius A* and Milky Way moves too, so we are never in the same location again. Love these explanations videos, thank you very much for making these!
Everything in the universe is moving, and at great speeds and in different directions. Between the earth's rotation, earth's orbit around the sun, the solar system's orbit around the center of the galaxy and its independent movement within the galaxy, and the galaxy's movement through space it's estimated that we are moving about 530 miles per second. And in ever changing directions. Wormholes, being transitory and unstable foldings of the space-time fabric would be pretty hard to find if they exist at all and even harder to re-find after even a split second. And considering that there is constant movement for both ends of the hole, I think the possibility of ever using wormholes to get where you want to go would be pretty slim. Humanity will be extinct long before we could ever get that technology. Even the concept of the existence of a precise point in space is pretty unsure and abstract. Any point has to be defined by its relative position to other points, but if all the reference points are also objects moving in different directions and at different speeds how can one ever define the location of a particular point. In a fraction of a second all reference points will have moved so far that they become useless. So not only is it impossible to define or fix a particular point in space, doing so would not serve any purpose. Nothing is attached to a point in space. Everything is composed of and is relative to matter or energy, and it is all moving continually. So a wormhole from one point to another in space would be useless unless somehow the portal (on each end) were attached to an object in motion and moved right along with it. Instead of looking for wormholes to crawl through it would be better to locate a good healthy worm and ride him through.
@StarTalk Hi Dr. Tyson, would the wormhole impose any negative effects on the space between the two openings that become bent after wormhole creation? For example, more gravity in that space due to increased curvature and thus changing planetary orbits if planets were present there? Thanks!
Love the series! And quick Q, Even if we are able to stabilize a wormhole, do you have any idea how we even go about controlling its destinations within space? AND, modeling space and time as 2 space ds and 1x time d, what's to stop the wormhole travelling through the time dimension? 👍
Glad you guys squeezed some science talk in that 17 minute glow forge ad. But for real I am glad a cutting edge 3d printer developer sponsored you. They know their market. Saving for one now. Thats a lie, I have no intention on buying one
This guy says it is almost impossible for beings from other star systems to visit because of the great distances but when he wants to, he talks about worm holes and how you can travel great distances in a short period if time. I wish he would be more consistent.
What if dark matter is just matter trapped in-transit between wormholes, in a 4th dimension outside of our observable spacetime but still has a detectable gravitational effect on what we currently consider to be our universe as we know it?
