Re: The science of riding gravity waves
Well maybe there will be someone along soon who could explain it to us.

Re: The science of riding gravity waves
i'll try...:
movement of all matter distorts space-time. when something moves it creates gravitational ripples, that squish everthing in their path along one axis (and strech about the mutually orthogonal axis)
unless you're looking at an incredibly large mass (i.e. a black hole), these distortions are unbeleivably small, and so rather difficult to spot.
i think the idea is we'll get to learn more about massive objects, if these waves can be 'seen'.
(feel free to correct this, anyone!)

The car is already moving, it's just your perception that says it's still.

...and this will end world poverty how?
Astounds me that they have time to do this sort of stuff. Let's face it, our movements in space time, the ripples of black holes etc doesn't really make much difference.
They need to watch a bit less Star Trek and get a life.

seriously though, you do have to wonder sometimes if the quest for knowledge is the highest priority...

I'd like to withdraw this post because I just found the following:
Quote:
Page 1439 question 37.19
A pursuit spacecraft from the planet Tatooine is attempting to catch up with a Trade Federation cruiser. As measured by an observer on Tatooine, the cruiser is traveling away from the planet with a speed of 0.6c. The pursuit ship is traveling at a speed 0.8c relative to Tatooine, in the same direction as the criser. What is the speed of the cruiser relative to the pursuit ship?

A rep point for whoever posts the correct answer.

You need to account for time dilation.
No I did not make that up.
