if you travel 2x the speed of light for one hour, and turn around and look through a telescope, what u see?

Answer 1

You would see the far mouth of the wormhole you just went through.

The only way to travel at what seems like a velocity of 2c is to leave the universe. One way to do this is though a wormhole that punches through a spacetime warp in a higher dimension. If the other end of the wormhole opened back into this universe 2 light-hours away, you would have seemed to have travelled for an hour at 2c.

Your subluminal velocity through the wormhole wouldn't matter as long as there was enough spacetime warped around it.

Answer 2

First of all it is not possible to travel at light speed and double the speed of it is just out of the question. Now, suppose if you travel 2x the speed of light and look back, you wont see anything by naked eye or through a telescope. Because telescope will also be traveling with you at that speed and when you try to watch through it, your vision will be limited to only light falling on your retina and that will not match with your double speed. Light coming from the other object will remain limited to speed of light and you are rushing ahead at 2x the speed of light....so you will see nothing.

Answer 3

If you could travel at twice the speed of light for one hour I guess you would leave the light way behind you.
Now I suppose you will ask what is the speed of dark so that you will know how fast to travel to get back to the light.
Best if you just sit tight and travel in and out of the light as the
Earth rotates.
Contrary to scientific opinion Light does not travel, there is no visible movement so the movement cannot be measured over time to determine how fast it moves.
Time is used to measure the movements of the Earth as it moves in and out of its own shadow.
In the course of a year every place on Earth is exposed to 50% light and 50% dark. The light is always there and so is the Earth's shadow, even if you are blind and cannot see it.

Without light you are blind, the lens of the eye interacts with light instantaneously when it is exposed to it. If there is a delay in the interaction it is a fault in the lens not a delay in the arrival of the light.

Answer 4

If you could travel 2xc, then you would run into the light. I think you'd only see a dark mass from before since the light cannot keep up with you.

But if you looked at your travel at an angle, I would guess that you would see a white streak.

But I have no idea how to build a warp drive to test that theory.

Answer 5

I will not go so far as to say it is impossible - nothing is; but, as of now we cannot conceive of a means or mechanism that would allow anything near light speed travel, and certainly nothing beyond it.

To anyswer your question, if you turn around you will see what you wold have seen if you had been standing at that point the whole time. Your ship, the only relevant item in motion, would have receeded to an unresolvably tiny point at twice the speed of light.

Answer 6

While I can appreciate your question in theory, it is important to realize that travel "faster" than, or anywhere close to the speed of light, is impossible.

Apparently you seek to look at yourself approaching "you".

Let me suggest that you recall any films or documentaries which showed seated astronauts belted into their cockpit seats and undergoing the tremendous "G" forces at liftoff.
While I don't have the exact figures at my finger tips, I think that those guys were experiencing 10 to 15 "G"s. And, what is more important, they were going from Zero to about 25,000 MILES PER HOUR in that liftoff.

You suggest travel at 2X the speed of light which is:

2 times 186,000 MILES PER SECOND...notice the last word, second. There are 3,600 seconds in one hour. So
if we examine the speeds on an equal basis, both in miles per hour, that would be:

25,000 Miles per Hour
and
2 x 186,000 x 3,600 Miles per Hour = 1,339,200,000
MILES PER HOUR

That is well over a Billion Miles Per Hour.
The "G" forces you would experience would squish you into
a mass of goo in nothing flat.

and, if you really think about it, you would see very little due to the problem of eye focus. It takes a lot of time, in reality, to fucus your eyes on a given object that is moving. It would not be possible to focus your eyes on something / anything moving at speeds such as the speed of light. By the time your eyes reach "focus" the object or view is long gone...

Answer 7

actually, the formulae that say traveling at the speed of light is impossible... and the ones that make is really really tough to even get close, don't say you can't go 2x. 2x is probably a lot easier than .9c, but there is that tiny problem of getting past c.

Answer 8

In a strictly hypothetical because of the fact that, you would be superb on your assumption. whether, no variety of rely could be speeded as much as the cost of sunshine no longer to point exceed it. If rely ought to attain the cost of sunshine, it does no longer be rely anymore (spaceship and passengers) does no longer exist. on the cost of sunshine, all atoms would implode upon themselves and stop to exist. for occasion, in Einstein's particular relativity concerning time dilation: t' = t x sq.(a million - v^2) in case you return and forth at say, 0.8 c, then: t' = a million x sq.(a million - 0.8^2) t' = a million x sq.(a million - 0.sixty 4) = 0.6 c on your reference physique. Now, in case you return and forth on the cost of sunshine: t' = a million x sq.(a million - a million.0) = sq.(0) = 0 there is not any time, and rely collapses upon itself and implodes starting to be organic ability. in case you go a million mile and hour swifter than mild speed: t' = a million x sq.(a million - a million.00000001) approximately. Equals t' = a million x sq.( - 0.00000001) it is a complicated variety suggesting a line of return and forth (time-line) at correct perspective to common area and time at under the cost of sunshine. The above is purely attempt at toying with the numbers. the element is, there is particularly in all probability a fact previous the cost of sunshine, yet we will on no account see it.

Answer 9

For that one hour, you see black. As soon as you stop, you see the past 1/2 hour history.

Answer 10

You cannot travel faster than light. So the question does not arise
