Understanding Spacetime

  1. Apr 25, 2010 #1
    I answer many questions thanklessly in IT forums so thank you in advance.

    I am trying to understand spacetime. My question is:

    Is it right to think of spacetime like whales in an ocean. The way they displace water is the way matter and energy displace spacetime? Or am I thinking in the wrong direction?

    thanks :)

    Can you be a little more descriptive and specific?

    I guess one example would be an orbit. Do I think of the earth displacing spacetime to cause the moons orbit?

    I guess another would be approaching the speed of light. Is it that space time is being displaced & therefore the object is slowed?

    I recognize displaced it not the correct term, but I'm trying to wrap my brain around the concept & it is the best word I have at the moment.

    Maybe you should try to explain your thoughts in other words. I have no idea what you mean by "displacing spacetime."
