The Big Bang...

"Which" Big Bang are scientist looking for?

The "Big Bang" theory assumes that TIME exists. That is a fallacy. We experience time, yes, but that does not mean that it exists. We say it exists because we experience movement. And we see movement because we experience time. The one depends on the other.

Einstein "proved" that time is relative. A step in the right direction...

One way to understand what I mean is this: Draw a line.
Now ask anyone: If you were to draw a never-ending line from one point, where will you eventually land up? The chances are that you will get this answer:"Where I started".
True. That is because you never left that point. In fact each point on the line is the same as the previous/next one. So your position on the line has no significance to the existence or not of the previous or next one. Had you not drawn the line, there would be no point.

Back to the Big Bang! Live the moment (if you can) and you will experience no time, no movement, no Big Bang.
Believe that time and movement exists, and you will find that the universe is full of Big Bangs... so which one are they looking for?
