There are 359 comments on this video with people trying to explain it. This is too big for anyone on youtube to wrap there head around. Steven Hawking has ONLY 12 students in his class, in his book he stated that only 4 people in the world know what he’s talking about when he speaks.

So when you travel at close to the speed of light, the distance don’t matter as the time stands still. So whether the planet is 20 light years or 200 light years away, I will be there in an instant since like I said, time stands still.

Comment #2:
Now if you travel at 10 m/s (A FAST SPEED), then:
Relative to time, you are moving at 299,792,468 m/s and that makes the statement that relative to you, time is moving at 299,792,448 m/s ! Congratulations! Time has been slowed by 10 m/s ! And if you are fast enough, like you are traveling at 299,000,000 m/s, time, for you, will be traveling at only 792,458 m/s.
Now if you travel at exactly the speed of light. . . or the speed of time (that’s the same), relative to you, time has stopped

Comment #1:
The Best way of explaining time slowing down is not by this stupid photon clock phenomena but there is a better way of doing it if you know the basics of General Relativity. . .
Lets just say:
When you are standing still:
Relative To Time, you are moving at 299792458 m/s
and relative to you, time is moving at 299792458 m/s.

Travel at the speed of light (in vacuum) is possible. . . exceeding it is impossible, according to the STR. In the appropriate special Lorentz transformation, be sure to let the numerator go to zero along with the denominator. . . otherwise the transformed time will blow-up as v->c-.

well no, time keeps slowing down as you approach the speed of light, so if you were going the speed of light (which is impossible unless your mass is 0) then time would stop

Time would go so slow that it would start to creep backwards, and he would be traveling back through time. . .
I think

You can’t beleive its 1:42am and I’m still reading about this stuff. I’ll figure it out!

What do you suggest?

maybe they need a better clock on the rocket ship? Or a better way to measure time?

@drone,
the video already answered you on your question. If Bertrand is travelling near speed of light, he will see albert’s light travelling in speed of light. It’s one of the basec laws of relativity – that light travels always same speed.
If you travel 0,9999999_c and you send a light pulse ahead of you = you will see that light pulse travelling 1c from you. It’s caused by the time dilation itself.

right I meant at the speed of light. Which also is not possible, how about almost the speed of light?

Objects which doesn’t carry information can travel faster then light. in vaccum

Would it be correct to say that a space ship traveling at 90% the speed of light would need about 3 times the amount of energy to see the same acceleration that a space ship needs that is standing still?
The idea being that the rate of time behind the traveling space ship runs 35% times slower.
Imagine a triangle with sides 1 and . 9 -> 35% give or take.

So what happens if bertrand is moving faster than the speed of light? How would the light from albert’s head lights appear to him?

you can SEE the past but you can’t BE in the past. you can BE in the future but you cant SEE into the future

however, i just looked into it: It would seem that the most distant object in the sky visible without a scope is the andromeda galaxy, 2. 5 million light years away.

well yes, if you are looking through a powerful telescope, but most of the stars you can see with your naked eye at night, is not further away than just a 1000 light years.

Not only that.
If you look at moon, you see also the past – cca two second past.
But basicly everything you see is history. Humans are not able to see the present, only past. More fascinating it is if you imagine yet that everyday you look into past, and travel to the future – all of this we do daily. (and yet some people doubt the time travel is not possible lol
)

That’s just a theory Rimdeker. At least to my knowledge.
The relativity doesn’t apply to the light, or speed of it.
To use relativity correcty I would say that if you travel infinitely close to the speed of light, then you are everywhere instantly, with (almost) no time delay.

canzt2 , yes that’s it but travelling with the speed of light is impossible and would mean that you do not move in “time” , at all. Means , you could be on a planet that is twenty lightyears away in an instant, no delay, at all. And then you could fly back to earth. Even though the trip took you NO TIME AT ALL on earth fourty years would’ve passed.
You do not need to move at the speed of light for this effect, it happens with every movement but the faster the greater the effect.
