Gravitational Waves from the Big Bang

Thursday, March 20, 2014

This week, scientists announced that they've found evidence of gravitational waves, a long-predicted twist in light from the Big Bang. The finding offers proof of the theory that the universe expanded extremely quickly in the first fraction of a second after it was born. Clara Moskowitz, an associate editor at Scientific American, explains what this discovery means and what it tells us about the creation of the universe.

Why so complex people? The answers are much easier to find in the fourth Dimension with a few simple steps to get back on track.

My TXC aren't we impressed with ourself? And apparently it's important to impress everyomne else by dropping your Sutton Place address. Don't you wnat to tell us about your Mercedes too?

No one who graduated from high school should be in any way confused or baffled by these findings.

Very amusing program. The more I listen to science types explain the universe, the more I realize theirs is just a much more complicated creation myth, compared with earlier, less sophisticated tribal ones. So, to each his own.

Does this tell us anything about the nature of time, whether it is accelerating, etc.?

How did the first, pre-grapefruit-sized speck of matter - that would become the universe - come to exist?

With the first evidence of cosmic inflation, what I want to know is if the universe was still an equation at the time it had no terms! ;-)

Is the less than trillionth of a second at the big bang much different than that of our time scale with the intense gravity due to general relativity?

Could we say that at infinite density time actually stopped?

In the beginning [of our universe], God created the heavens and the earth. God said, "Let there be light" and there was light.

Why the South Pole for a vantage point?

This conversation is fascinating. It feels like neither participant really knows the subject but have been well prompted, well tutored to discuss it. And I certainly don't have a clue what they are talking about.

As they say in Massachusetts, this is wicked cool!
