A warp in the TimeSpace continuum!

Einstein also theorized that really big objects, like planets, warp the TimeSpace continuum around them. The example often used to illustrate this idea is a bowling ball on a trampoline. The bowling ball is so heavy that it makes a big downward bulge in the surface. Then you roll a marble around the edge of the trampoline. The marble feels a pull toward the bowling ball as it circles around the trampoline. A huge object like the Sun is so enormous that it bends TimeSpace around it. Like the marble, planets are pulled toward the Sun as they circle around. Don’t worry—the planets don’t go crashing into the Sun! Why not? Because they’re set in their orbits around it. There’s a balance between the Sun’s gravity (pulling Earth closer) and the Earth’s centrifugal energy (pulling Earth away) as she orbits. This situation has existed for billions of years.

Here are some cartoons.

It’s time for Einstein’s General Theory of Relativity!

It seems Time and Space aren’t two separate things after all. They’re 2 parts of one thing: TimeSpace. They’re what’s called a continuum.
1 : a coherent whole characterized as a collection, sequence, or progression of values or elements varying by minute degrees

The Sweet-Salty continuum

I suppose a piano keyboard could be considered a continuum: lowest note on one end and highest note on the other, with the keys in between playing both low and high. You could draw up a continuum of food—from, say, the sweetest food you ever ate to the saltiest food you ever ate. Where is barbecue—both sweet and salty—on your continuum?

The continuum of TimeSpace has extreme ends, too—one end nothing but time and the other end nothing but space. This is really hard to think about. Time passes on one end but nothing physical is there. There’s physical stuff on the other end but nothing moves because it’s outside the medium of time. We live in the middle. We’re physical beings in a physical world who walk around and grow older and have kids and live our lives while plants sprout, bloom and die and the planets and stars whirl around in space.

(Does any of this remind you of Sunday-school? I mean how the Bible starts: “In the beginning…” and then God creates the universe, the Earth and the heavens, separates day from night. It’s how the Bible explains time and space. Which means God exists outside the TimeSpace continuum, which is too much for my brain to handle.)
