Considering General Relativity, how would earth appear to a space traveler accelerating to near light speed? - digital travel clock
According to relativity theory seem that should be able to return to the Andromeda Galaxy Travel (2 million light years away from us) and then to the ground, for a period of time may be a few years for me. But after my return to earth, I find that the earth at the age of more than 4 billion years ago. Now let's assume I have a very, very powerful telescope, and I still see the large digital clock on the surface of the earth that was created for my viewing pleasure. My plan is to spend my whole trip to watch this space-based global clock. If this is not accelerating, the clock seems to be very slowly - at speeds close to light, seems to land next to the clock will be stopped. According to the special theory of relativity, the earth seems to fly at almost the speed of light compared to me, I see the clock on the ground slowly. But when I am accelerating, the need and the general theory of relativity. So my question is ...

The answer to your question lies in the search, on the edge of the universe. As seen on the edge of the universe that we see as millions of years. If we are able to rack we would not be all that we see through our Earth with a telescope.
So to answer your question would seem like a journey into the clock of the Earth to Bearly have moved. However, if he returns to earth, everything would be what you have changed the world, but as a relic of the past few years, Bearly's.
You use a variant of the twin paradox.
The fact is that someone can say during their opinion is valid, if you slow down and change direction, go back to earth, he renounced his views relativist. The earth can boast that they are still used, but can not.
In addition, take the opportunity for you in the course of time on this earth - are changing as we move extended far away, the waiting time for you to slow - Transmission of light perception.
But the return trip is the opposite - the company, reducing their perception of passing time on Earth.
On the go, time seems to pass "or" back half that on Earth, but on the road seems to spend twice as fast - if he returns to the mathematics that describes everything that is right, then you're back in the sync.
The Clock of the Earth seems to be slow, but the feeling that you are here for slowing and acceleration, which would be experienced by the expansion of real time. So the earth at the age of four million years would be for a few years. Although I do not know how he could endure G-forces
just think that if you leave the universe, no time. I know it's hard to understand my answers, but we think
It is really an example of time dilation, at speeds near C in the second postulate of the Ernestina. because time is not absolute, as compared to C, which is experiencing a period of time shorter. while the age of the earth on its regular rhythm. If, therefore, at a clock of the Earth, which is slower than real time (time), so that the general theory of relativity, the clock will appear to the earth faster than yours. Area expansion depends on a number C, the ling in Travel
You do not need general relativity to the problem. Relavity special because you always Euclidean framework for all stakeholders. GR deals with gravity.
And the answer is that the clock is always faster than him to cut quicker.
You could see the clock move very quickly.
This was verified experimentally using particle accelerators. There is no ambiguity in the acceleration is included in the price.
