>avoid time dilation

You cannot avoid time dilation in space. This is fucking laughable. If you knew any physics at all you would realize this basic fact.

Even with Warp Drive time dilation is unavoidable. Just about every region of space is moving and rotating. No matter where you go, your clock will be skewed from that of earths. This happens even at high altitude on earth. It is impossible for any space craft to keep the same "tick rate" with that of earth, no matter what the speed.

Sleep is akin to "brain defragmentation".
This is a ongoing area of scientific study.

questions?

\thread?

So im trying to get a head start on a chemistry class im taking for the fall, and i was wondering if someone could guide me through the steps of this question:

An astronaut finds chlorine abundances of 13.85% for ^{35}Cl and 86.15% for ^{37}Cl. What is the atomic mass of chlorine for this location?
