Hello everybody,
I am sorry, but I need your help with my physics homework. I will be very happy if somebody could help me.
1. Homework Statement
Task: The ship passed through the wormhole. The “new” temperature of cosmic microwave background is T = 0,3 K. The curvature of the universe is...
Homework Statement
It's not a piece of homework, I'm doing a project and I've been wondering how I may be able to show it mathematically. I've covered the material before but it was a long long time ago...

Suppose I'm an observer out in space and 30 km from me there's another observer, who is static with respect to me. Let's say my name is A and the other is B. We're both far far away from all the cosmical objects that might have a gravitational influence on us.
We both notice a spaceship flying...
If I'm travelling on a spaceship at a constant velocity (say 10000 m/s) towards Mars will I feel weightless, or will I feel nearly weightless because I will still be slightly affected by gravity?
I know that when astronauts are in the ISS they feel weightless because they are in a constant...
Homework Statement
A spaceship leaves Earth at time ##t=0## with constant speed ##u##. Its clock is synchronized with the terrestrial one. At time T an earthling reads with an optical telescope the clock inside the spaceship. What value does he read?
Homework Equations
Lorentz equations.

I believe length contraction always makes more sense when integrated with reminders of relativity of Simultaneity.
Let's say the engines are at the back end of each rocket. For the viewer "A" in the initial frame, they begin moving and continue accelerating simultaneously, and clocks next to...
Let's imagine say, a spaceship is going through space at 99% the speed of light. Relativity says (to my understanding) that as the spaceship increases in speed it's mass will increase and it shall also get slightly shorter. Let's assume that energy isn't a problem, should the spaceship continue...
