Using the Lorentz transformation, at what speed relative to speed of light c must you travel so that your length along the direction of motion is seen to decrease by a factor of 2? For this speed, hwo much would your mass be increased? Please show steps, I'm confused with this question!

Which of the common cosmological models do you prefer and why? Assume we don't know which if any of the models is the actual one that matches the universe.

How much more of less would you weigh (same as force) at the surface of the sun than on earth?

If your entire mass were to be converted to pure energy, how long could you provide a MegaW (10^6 W) of energy to help in solving our energy crises?

help! how much more or less would you weigh (same as force) at the surface of the sun than on earth?
