a planet is 20 light years away, i travel away from it at 20 light years an hour what do i see?

Question

i'm watching it constantly through a super telescope, do i see time reverse in super speed?

ok if its one light year away then and i travel the speed of light away from it? watching it continuously?

i'm speaking hypothetically? do you people not have imaginations?

Answer 1

you are traveling quite a bit faster than light, so i don't think you would see anything. i think that what you would see is an extremely bright universe in front of you and nothing behind you. from the observer, well they wouldn't be able to see you but if they could you would look like an extremely bright comet with a dark tail.

no, i don't think that you would see time go backwards. the light has to catch up to you to see that. all you would see is darkness because the light that you would see can't catch you.

Answer 2

It's okay to talk about imaginations, but ur imagination is running a bit too wild dear.
I guess, consider the fact that u r moving at a speed of 20 light years an hour, it is a fact that light won't reach u, n u will be seeing nothing after a fraction of a second that u start ur travel at such (an amazing and very stupid) speeds.

Answer 3

I don't know about 7232 KMH but I computed the distance using the Speed of our fastest space craft, the two Voyagers. I used Astronomical Units (AU) for my unit of measurement, just to keep the numbers small. 1 AU is the average distance between the Earth and the Sun. Light Travels 63,241 AU's in One Year. Voyager 2 Travels at a speed of 3.3 AU's per year. Simple division> It would take Voyager 19 THOUSAND years just to go one light year. Multiply that by 20.

Answer 4

You wouldn't have to stop to see it as a previous answer suggested. Einstein's thought experiment of keeping pace with a beam of light led him to the paradoxical conclusion that no matter what your frame of reference is, light appears to be travelling to you at the speed of light.

What you would notice, though, is that the light from the planet would shift far into the red end of the spectrum as its wavelengths were spread out over the increasing distance bewteen you by the Doppler effect. The light might even shift into an invisible frequency (the infrared range) and you could lose sight of the planet.

Answer 5

You could see the light which left the planet at some time in the past, and has just reached the position you are at. So you would be looking into the past. However, you would have to stop to see it, as it could not hit you if you are moving away from it and looking back at the planet. You could be looking forward, in the direction you are travelling, and collect the light as you move into it.

Answer 6

You can't travel faster than light, it would take a minimum of 20 years to reach a planet 20 light years away (if we had a ship that could travel at light speed)

Answer 7

Nope, and here is why. It is impossible to travel 20 light years per hour.

Space and time or connected to each other the faster you move through space the slower you will move through time. What is speed??? It is a ratio of distance traveled over a period of time. For example 50miles per hour (distance pre time or distance/time) If you could get yourself to half the speed of light 335,308,314.5 per hour then time would move by at half the the rate it does normally for you. But someone observing you from a a stationary position would see you moving at 335, 308,314.5 per 2 hours or 167,654,157.25 miles per hour. Traveling through space and time is like thinking of travailing north and west. Lets say time is west and space is north. So if you are stationary you are just traveling through time(west). But as soon as you start to move through space you move less through time. It's like if you take your care that's moving west and you have the cruise control on at 50, and turn slightly northward, your still moving east, but a little slower then you were before because you are now traveling north as well. In fact the more you turn northward (space) the less distance you travel to the east (time) or the faster you move through space, the slower you move through time.

Now lets put you back on the spaceship with the super telescope looking back at you home panet, if you were traveling at half the speed of light then everything back home would be moving along twice as fast.

Lets now say you are in a race with a particle of light. And you have a super fast car that can travel 3/4 the speed of light 502,962,571/hour. The green light flashed and the flags go up and you take off, get your car up to it's full speed, and you see the particle of light happy move away from you at the speed of light, even though you are moving at at 3/4 the speed of light. How can this be? you ask, I'm moving at 3/4ths the speed of light I should see this light particle move away from me at 1/4 the speed of light not the full speed of light. Well becuse you are moving through space at 3/4 the speed light, you are moving through time at 1/4 the rate you would if you standing still.

Answer 8

The posted speed limit in the universe is the speed of light. A really smart guy named Albert Einstein figured that one out.

Answer 9

You will not see the planet change at all , time will stand still at this point for you. but not around you

Answer 10

Not to mention the fact that your eyeball would be infinite in length (to an observer in another frame of reference) and mass.
