Drakkith,
Thanks for the reply. I apologize. I didn't mean to offend anyone. I didn't even know it was offensive to conclude that mankind doesn't understand the universe. I would think that to believe so would be arrogant. I have a lot to learn. I'm not going back to inclined planes and...
OK, fair enough. But I am not talking crap. I admire all of you who are rigorously seeking the truth. But I think so many theories are so speculative that they stray into at best, metaphysics, and at worst fantasy. I am not a physicist. I am an engineer. I may have wandered too far into...
I am drawing a conclusion now. My conclusion is that there is nobody living on Earth today who has the slightest idea of what the universe is, much how it was created and where it is going. I think it is time for me to go back to inclined planes and pulleys.

The link you posted is saying that some distant galaxies are moving away from us faster than the speed of light... well here it is:
"perhaps more surprisingly, some of the galaxies we can see right now are currently moving away from us faster than the speed of light! As a...
Thanks mikmik, then I would want to know what is it about the condensation of (or to) matter that put the brakes on expansion or at least the incredible rate of expansion of the early universe?
And let's assume the diameter of the universe is 42 billion light years as you read. How does that...
Fair enough, the universe (space and time I guess) expanded, continues to expand, and in fact, accelerates faster than light. So if that is true, what is the rate of expansion? Can it be measured, or even calculated, from known facts?
I was watching a science program explain how once we discovered the Universe was expanding, it was a "simple" matter to imagine it rewound; and, to reach the "obvious" conclusion that it must have started from a single point. It went on to explain that the universe expanded to the size of an...
Well, since any attempt to imagine ourselves personally in the past appears to be totally conjecture, I wonder if anyone who has seen the move "Source Code" has any thoughts about how the screen writers attempted to make the story idea plausible. The head scientist (in the screenplay) in...
jiohdi, I think that is a good intuitive analysis of what moving back in time would require. I think you are saying that going back in time is the equivalent of rewinding the big bang itself. Since the energies are unspeakably massive, it does indeed appear that it is impossible.
I think...
jiohdi,
say what? Can you explain that in layman's terms. I just read Einstein's 70 page explanation of Special and General relativity last night and it was loaded with metaphor and easy to grasp visual models (train tracks and lanterns etc). He even apologized in advance for repeating...
I woke up this morning and tuned in CNN television. I caught the end of a story about how a scientist in Hong Kong proved that time travel is impossible. I searched recent news stories on line and came up with this posted July 24, 2011: "The Hong Kong University of Science and Technology...
