Attention Out-of-the-Box Thinkers...

... Roy Lewallen, W7EL Roy: You remind me of a physics instructor of mine from 1970. He brought in a very thick piece of foam rubber, a bowling ball and a tennis ball. He placed the heavy bowling ball in the center of the foam rubber; it sank, very pronouncedly, deep into the foam rubber. Next, he placed the tennis ball some distance away, on the foam, from the bowling ball; immediately the tennis ball rolled towards the bowling ball and rested against it. He then stated, "Gentlemen, that is an Einstein gravity well! Now we will have a real look as to why." chuckle Regards, JS |
