Web$\begingroup$ This is all merely definitional. Yes, you can define a "speed" through time simply as the proper time registered by the object per coordinate time. This allows you to define a "speed through spacetime" if you like (as Greene seems to). WebEnergy can be found in many things and takes many forms. There is potential energy in objects at rest that will make them move if resistance is removed. There is kinetic energy in objects that are moving. The molecules making up all matter contains a huge amount of energy, as Einstein's E = mc ^2 pointed out to us. Energy can also travel in the ...

WebNov 19, 2014 · 2 Answers Sorted by: 19 Because in the frame of reference that is co-rotating, the object doesn't move, and therefore it has no kinetic energy in that frame, which is the frame in which most problems involving objects on earth are looked at. Note that kinetic energy is evidently not a frame-invariant quantity, but it is not required to be.
