If a person is accelerated to, say, 50% of the speed of light, he or she will be subject to actual time dilation, e.g. twin paradox. Is the accelerated person also subject to actual length contraction?

Relativity time dilation applies to photons. Do they experience time at all? We see photons created, travel at the speed of light and end, but they see no time, so they don't distinguish their lifetime, they simply exist in a universe with no time.

If, as has been explained, time goes slower in a gravitational field, why is it common to say that someone moving at a speed close to that of light ages at a slower rate than an observer?

On a revolving disk two different points at different distances from the center will be rotating at different speeds, so if I have two people at those points and rotate the disk at speeds close to light speed, will I have one younger and the other older after some time?

Two ships are in an extremely time dilated field. Ship A sends a probe to Ship B through a less time dilated field so it arrives before light through the time dilated space can do the same. Will causality be violated? Why? Why not?

If time dilation is true, does that mean the universe is a different age from different perspectives or does it mean the laws of nature are different?
