Wanna see the speed of Voyager 1 at ground level (60,000+ km/h) ? Then check out my latest video! : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-130_TH5dJ94.html
What’s even crazier is that even with how fast light is, the sun is so far away that it still takes 8 minutes and 20 seconds for sunlight to reach earth.
I learned about the difference between speed of light and speed of sound when I was maybe 5 years old at a park. I was looking at someone off in the distance. They were hammering tie-downs into the ground around a soccer goal. I could see them hit the metal with a hammer, and hear the sound of the hammer striking metal maybe a quarter-second later. I asked my parent to explain it to me, and they told me about how sound travels slower than the light we see by. I will never forget that visual.
The fact that it takes 8 minutes for Light to travel from the sun to the earth shows how vast our solar system is if it takes less than a second to circle the earth. Amazing.
If we could build roads to the Moon and Sun, and you drove in a car along them at 60 miles per hour continuously without ever having to stop for fuel or rest, it would take you 6 months to reach the moon and 126 YEARS to reach the Sun.
@Pink G.A.L Femm Phoenix A black hole is the most massive with an estimated 100 billion times that of the sun. TON618 would fit inside it with quite a large amount of room to spare.
You won't experience billions of years, on other side, and won't see anything around you [because time doesn't progress at that speed]. Just instant teleport to infinity
Octillions of years Thousands of septillions of years Millions of Sextillions of years Billions of Quintillions of years Trillions of Quadrillions of years Quadrillions of trillions of years Quintillions of Billions of years Sextillions of millions of years Septillions of Thousands of years
You actually would get there instantly but never since it's expanding. If there was an edge. Time itself would be a few billion years later but it didn't take you anytime to get there. At least that's how I remembered it worked. Light is pretty weird but fascinating.
My attention is gripped whenever that music is used! I love it. Great video. I know light and sound are way different in speeds but still amazing to see this
It is impossible to break the laws of physics.. its like your are going twice the speed you run in minecraft in a normal game.. which is impossible.. they haven't coded that..
When you take this into consideration. It really is crazy to think it takes approx 8 minutes for the light from the sun to reach Earth. Space truly is uncomprehendingly massive.
Yeah, but that's not what baffles me personally on that regard, like imagine how hot the sun is! To be able for it to be so incredibly far away, and still heats up our entire planet! That's crazy!
definitely. But personally what blows my mind is hearing that a star is like 50 million light years away. The fact that it will take light 50 million years to reach us considering its incredible speed gives me something like a headache and a falling-into-the-void feeling at the same time lol The universe is beyond mind-blowing, it frustrates me to know that I'll die and will never know its secrets.
Traveling at the speed of light would look exactly like "your life flashing before your eyes". To you a lifetime would've been lived, but to someone looking on, it would just look like you had blinked.
Exactly the opposite. As you speed up your perception of time does too. So for the photon, no time passes. Travelling 90% the speed of light, you would experience half as much time as everyone else.
One thing that always impresses me is the surprisingly large amount of water on the earth. We often don't realize it since we only see maps, where the pacific ocean is usually split anyways. But the entirety of the pacific is actually massive.
It’s also interesting that the earth is barely water. It’s 99.9% not water. Theres just a tiny bit on the surface. 8 miles is the deepest part of the ocean. It’s 4000 miles to get to the core. Wild!
Crazy to think about but if you stood at the end of a long street and you made a very loud noise you could theoretically travel backwards all the way round the globe at light speed to the other side of the street and hear the noise you made
It wouldn't even have to be a long street! In the time you took to circle the world at light speed, the sound would have travelled less than 50 meters.
Really puts into perspective how massive the universe is. Traveling at this speed it can take thousands to millions of light years to reach other stars.
It really does take long lol the closest exoplanet promixa centuri b is over 4* lightyears away. you have to go this fast for over 4* years, crazy. the closest earth like planet is 30x that distance. that's not even 1% of the milky way either, let alone traversing it or going to to other galaxies. not possible with speed. would explain our lack of visitors.
The colors would change. Traveling in that speed (edit: close to the speed of light, because AT the speed of light you wouldn't experience time or space from outside) would cause the light coming from the front to hit you with a lot more energy and cause a strong blueshift, and colors like violet and blue would become invisible, the'd hit you like ultraviolet. And if you look back, you would barely see anything, because the wavelenght of the light that's coming for you from behind is now way bigger and would have a deep redshift. It's just like the doppler effect, but with light.
Well, assuming you have no mass and are moving at the speed of light you wouldn’t be able to see anything and the entire universe would be located at a single point from your perspective.
@@tomaszmagruk4845 it's because when you travel at the speed of light, you will not experience time at all. So you could travel forever through the universe without any time passing. From your point of view, there is no "distance" because your travel time to anywhere in the universe is zero.
It's surreal to imagine that it would take over 105,000 years going at that speed to span just the Milky Way Galaxy, and it would take 2.5 million years of going that speed to even reach the next galaxy.
Huh. I've always heard it was 200,000. Just looked it up and it's not. Maybe I misremembered or something. It's actually 105,000 light years. Still a ridiculous distance either way.
It’s insane to imagine that even if we could travel at light speed, it would not be fast enough to explore much. In fact, it would still take over 2.5 million years to get to the closest galaxy outside of the Milky Way.
@@Spyciality Im not quite smart enough to explain it myself but I think it has something to do with the theory of relativity There are videos on it on youtube, I may be wrong about something tho Im not sure....
@@coopermuccio4409 superman is faster than flash..He even Beat Him In race But He don't run Cause superman Running Speed is so fast That It Can Harm Any grounded place Extremely Bad
@@debetrolence1991 And had since 1940s. Most handgun rounds travel slower than the sound of speed though and can still do a lot of damage so it's not that slow.
Speed of light = 186,000 mi/sec or 669,600,000 miles an hour. In comparison sound (though varies a bit due to temp, humidity, etc) travels around 750 mph. Things man has created has traveled faster than the speed of sound; however nothing can exceed light speed.
I’m always reminded how slow sound is when seeing videos like the explosion in Beruit. Or even the videos of the plane hitting the towers on 9/11 You see it happen and a couple moments goes by before actually hearing it. It’s wild Actually I remember the first time personally experiencing how slow sound travels when I was a kid. I saw someone shut their door from down the street and noticed I heard it like half a second later and I was like wait…
@@fbisecretagent6910 Do yourself a favor and get educated. You wear your ignorance on your sleeve. In fact, you proudly wallow in your ignorance. You are a laughing stock to **everyone** , including me, but yourself.
Some? We are only looking at the past, and only the past, im not sure, but there are plenty of stars we see that didnt exist any more.. And we wouldnt even know it, because that light still arrives
@@alexanderjanke1538 So what you're trying to say is we could be looking in the night sky at stars from years ago and some might not even exists anymore?? Great Insight
No, visually it would just be extremily bright in front to the point where you couldn't see anything due to you running into a large number of any photons not moving directly away from you in such short time, and then you'd see nothing behind you because light can't catch up to light. Of course this is ignoring many laws of physics. Pretending you are somehow a conscious photon (as mass cannot move the speed of light), time would stop for you so in your perspective you'd just seem to teliport instantly even if you go somewhere billions of light-years away.
Fun fact about relativity: from light's perspective it gets everywhere instantly. Let's take a photon being emitted from the sun. From the photon's perspective, it would instantly arrive at Earth. From a non-realativistic perspective, that photon takes 8 mins. The reason that photons travel instantly from point to point is a fun property of math. Distances appear shorter the closer to the speed of light you get. This is to say it would be really boring as in your perspective you have not moved, but everyone else is 0.13 seconds older.
For anyone else who was confused by the 8 frames, the trajectory shown is not the same line the frames are from. Also, frame 6 and 7 should be swapped, assuming they meant some part of the Sahara desert instead of Saudi Arabia
if he did he also misplaced zimbabwe as 7th frame@@brunogonzalezprado1306 edit: ok that had to be the case, i didn't notice he shows trajectory later in the vid cuz i paused and checked it myself
I am amazed so many people believe the speed of light and the speed of sound are even close. As Carl Sagan once said, "We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology."
@@romansenger2322 as obvious it might seem there's a lot of people who have no idea where the sun goes when it sets. There's a show in my country where they ask people such fundamental things and they don't know.
As a kid, speed and time fascinated me so much. The speed of light, the speed of sound, terminal velocity, seconds becoming minutes becoming hours becoming days were, for whatever reason, such marvelous concepts. One of my favorite things to do was to guess how long it would take for events to happen and then time them. Examples included: Pulling the trigger on the nozzle -> water coming out of the hose, flipping a light switch -> light bulb lighting up. Everything always happened so much quicker than I thought. To this day I am trash at estimating literally anything (weight, size, speed, time, number of jelly beans in a jar.) Awesome video.
I've always been the same way. I always wanted to measure how fast the light came on after flipping the switch. How long does the sound last after a single hand clap or finger snap. I reasoned that it couldn't be infinitely short, but it didn't seem to be long enough for me to time it with a stop watch. I tried to see how fast the light from a flashlight would travel from the device to the moon. Obviously I didn't have the means to do measure these things as a 5 year old, but the concepts have always fascinated me.
Kudos for managing to go round the world so fast that the camera man even had a chance to take a pic at Saudi Arabia despite not being on the trajectory.
@@GreenBlueWalkthrough The Milky Way Galaxy is about 100,000 light years wide. So if you wanted to do it in only a year, you would have to go 100,000 times the speed of light. If you wanted to get to Andromeda (the next closest galaxy) at this speed, it would take still 25 years.
The fact that is STILL takes 0.13 seconds for light to go around the earth is still crazy. Like imagine a phone call from Perth, Australia to NYC, that's a >0.1 second delay built in that can't be avoided.
Actually Zimbabwe was South and the other frame was around Mauritania. So I really wonder how the hell would it go from Zimbabwe to Arabia when it's like 80 degree difference
And it's even crazier to think that, despite how significantly, mind-bogglingly slower sound moves than light, the vast majority of humans alive in our modern world have never even gone that fast since commercial airplanes cruise comfortably under Mach 1.
@@timonsolus Concord would have swiftly been retired anyway do to exorbitant cost for insufficient gain. Supersonic atmospheric flight is just too expensive for transport.
It boggles the mind knowing that even at this immense speed it would literally take 10’s of billions of years traveling at the speed of light to reach the edge of our observable universe!!
The thing is...light doesn't feel time. So if you are travelling at the speed of light, you are everywhere on the trajectory at the same time. The time when you start the trip is the same as the time when you end the trip. Relativity tells us that when an object gets closer to the speed of light, time slows down - so at exactly the speed of light, time doesn't tick at all.
@@chainenationqc No. The thing is, teleportation doesn't really mean much when time doesn't tick. When you teleport, you are at point A, and then go to point B "instantly". But when time doesn't tick, even the word "instantly" doesn't make sense. At time t=0 you are at point A, and at t=0 you get teleported to point B, meaning that at t=0 you are at both points A and B and all the points on the trajectory between them. In teleportation, you are at one location at any single point in time. At the speed of light, you are at every possible location on your trajectory simultaneously. An observer travelling at the speed of light can't tell "now I am at point A" and "now I got to point B" because he would have to say those 2 sentences at the same time.
I remember once I stopped at a red light. The lights changed to yellow and the guy behind me honked at me to move. Anyway, the speed at which he did it was faster than the speed of light that reached my eye socket from that yellow bulb.
In my mind, I always imagined a light-year is how sitting at a traffic light feels like a year even though it was only a few minutes. That's why they call it relativity.
The light/sound speed difference definitely gives you the clear idea why you see a lightning flash before hearing thunder when you're miles away from the bolt in a storm.
@@lostinamattison23 lightning may not be light at the source of the strike, but unless you're being hit by it, it is processed as light from a distance.
An object that would move that quickly would have to be indestructible because it would heat up and explode the moment it moves at that speed. If it were indestructible, it would probably send a pressure wave that would melt a ring around the Earth.
@@TheRedRaven_ it would absolutely. The energy would be equivalent to millions of nukes, been a long time since I did the math but even coming straight down through the atmosphere (100 miles rather than tens of thousands) would likely cause enough of a temperature shift to melt the ice caps and ultimately end all life, besides leaving a huge crater (it would release more energy than chixculub, the dinosaur killer asteroid)
It's not back in time but rather a flight sim mod that flattens 1WTC and puts the Twins inside of the modern NYC skyline. To the left of the twins, you can still see 4WTC (built 2013) and to the right you can see the Goldman Sachs tower (built 2010)
It's a poor representation though. It doesn't take relativistic effects into account at all. At close to the speed of light, your perception would change drastically.
I have an uncle who's a mathematician try explaining the speed of light in a very easy and amusing way (I was twelve at the time): "If I could throw a baseball at the speed of light, and curve it perfectly around the earth, it would hit me eight times in the back of the head in one second." Pretty wild thought, even today.
he calculated each point of earth 1/8 times. then took a screenshot and made them into a 8 frame clip. it would be physically impossible for msfs to do that.
@@JustJory I think he meant slow it down, but as you said it would be much more efficient to calculate where it would be at those points and just capture those 8 points
pretty cool . now do one at the speed of thought. one could travel across the street or to the ends of the university in the same amount of time , like no time .
