Scientists have learned more about the expanding universe, thanks to many things, including Hubble. They have come to the conclusion that the universe is indeed expanding, as Einstein has proved, and at an ever increasing speed. In fact, the galaxies out at the edges of the universe have now passed the speed of light. We will never see them, we just know they are there. And what's so wonderfully magnificent, is that it is only the space between galaxies that is expanding. Any object that is interacting with another object through gravity is completely excused from the very principal of an expanding universe. Our planets are not expanding from the sun, our stars in our galaxy are not expanding away from each other in anyway other then the normal centrifugal or gravitation forces which are called for in the normal realm of science. If galaxies are being attracted to or repelled from each other in clusters, as many are, those normal laws of physics still apply. But as the universe expands, in galaxies that are no longer interacting with each other, the space between them expands. And at an ever increasing speed.
So here on earth we know that if a spaceship is racing ever faster towards another star, time slows as it approaches the speed of light, and Einstein has concluded that at the speed of light, time stops, and the craft will cease to exist; therefore faster then light travel is impossible. But on the galaxies at the fringes of the universe that travel faster than the speed of light, as if in a wave, were an astronaut to have hopped on a planet before it were across the light speed barrier, he would find on that planet that everything was normal. Time would be normal, apples would still fall to ground, the sun would still rise and set, there would be no notice that one was speeding through the universe beyond the speed of light, an unfathomable speed. Total and complete empty space moving it along, pushing it, pulling it, safely guiding it along through the fabrics of space, at a speed we can't even comprehend. It's happening right now out there in the universe, and it's the "still accelerating" that blows my mind.
I've no doubt scientists will zero in on the physics and mathematical formulas that make this possible, and try to replicate faster than light travel. They are trying now, even as we speak, and don't seemed to notice the enormity of what is happening. I'm sure the formula will read something like: G=O=D. The big bang theory brought them closer, but "the God" notion in that theory really irked Einstein. Maybe this next new equation will make it obvious even to a scientific thinker.
