A frisby is flat, but if spun and flung it will fly. The space is still curving.
Inside the frisby are molecules. They don`t care if the inconcievably large frisby is flat or not. The molecule`s timespace is curved.
I am/we are residing in mass bodies living on a massive planet surrounded by the orbit of a massive moon, all of us orbiting a massive sun, all rolled up in a massive solar system, in a massive galaxy, in this massive universe (with all sorts of low mass space in between).
The latest discovery that the universe is flat, like many solar systems and galaxies and all frisbies, does not prove Einstein wrong: timespace is still curved.
What is cool about the new theory is that it showed that the compressing photons released sound waves in the beginning of the universe! In the beginning was the Word and it was the fundamental tone of the harmonic universe.
The problem I have with a description of a flat universe or of any shape is that what do they propose for the outer universal boundry? Without mass there is no spacetime. We can`t have a brick wall at the outer limit. But to approach the language of no-spacetime is to begin discussion of the void, and that is sure to evade a boundry description.
So it goes. |
