Sei Italiano? Sono Canadese-Italiano.
And that's about all the Italian I can remember at the moment.
You're wondering if I make a distinction between Gravity and Gravitation - and no, I do not.
Perhaps translation does not work well for the standard idea of "warpage of space-time", so let me give you an example.
You have a sheet of rubber. Draw a line down one side of the sheet. Now, imagine poking (or pushing) on the center of the sheet of rubber. What
happens to the line? It bends. Not just 3-dimensionally (downwards), but also 2-dimensionally (to the center).
The rubber represents Space-Time. By warping the rubber 3-dimensionally, you produced a 2-dimensional change. When you warp Space-Time
4-dimensionally, you produce a 3-dimensional change. How do you warp the 4th dimension? Mass warps it. The more mass there is, the greater the
Also, since things don't "pre-exist" in a line, and since there is no "edge" to the universe (I can get more into that later, but it REQUIRES an
understanding that the universe is 4-dimensional in nature, not 3-dimensional), something travelling along this warped space will, although
3-dimensionally be travelling forwards, will have its path changed by the change in the 4-th dimension.
What does this mean? This means that when you throw a baseball forward, it's not being "Pulled" downwards, but rather its still going straight -
but straight-forward changes to become straight-down. It's direction is changed, not its energy.
So you can see now why gravity is really just an effect, and not a force. You also can see why greater masses have more gravity, and why things that
go into orbit aren't really in "Zero-G" but are rather just set on a course that changes into a circle.
