Well thank you, Quantum Quack. You have written very much in just a few sentences. Of course I will consider closely what you have said. I have to go back and read it again, and I will read it as many times as it takes me to understand. Thank you, again, for your invaluable information. Yes, of course - everything is relative. I understand Einstein perfectly. He, like Newton, was a very smart man. But he came up with his own Anti-Gravity - his 'Cosmological Constant,' and then all of a sudden he changed his mind on it. Actually, he didn't just change his mind on it, he denounced it in the strongest language possible, calling it 'the biggest blunder of his career.' I agree with Einstein, and knowing as I do (and I hope you do too) that AntiGravity doesn't exist, I can understand this perfectly. Einstein lived another 33 years or so after his denouncement, never saying anything about it except what a mistake it was. That's all Dark Energy is, Anti-Gravity renamed. The Universe isn't run by anti-gravity, but by gravity. It's a gravity operated Universe, and we're going in so Gravity is all we need. There was no Big-Bang - the Universe evolved slowly - from a huge cloud of Hydrogen, rather in the manner of our sun (Sol) just on a bigger scale. This is the truth, whether you like it or not. Our Universe is just one of trillions. We have to stretch our minds - people think the Universe is much too small.
