A mind-blowing scientific piece on the number of galaxies and stars

[BackAgain]

First, the link: There are more galaxies in the Universe than even Carl Sagan ever imagined

Second, the commentary: Not much. I'm not a scientist. But I do find this material fascinating.

The mere notion that there may be as many as 20 TRILLION galaxies "out there" and that so many of them have so many billions of stars, each, is astounding. The fact that human scientists now aided by computers and amazing telescopes of different kinds can make calculations about such things is impressive as hell. Although the enormous distances involved make it appear to be very unlikely that we are going to be visited by any alien life or that we will ever be able to visit them, I think the numbers do suggest that there has to be other life in our cosmos aside from life being exclusively on just this one blue-green little planet.

The Universe is constantly expanding and as Stars die, new Stars are being formed.
I agree that there is life in many other Galaxies, has to be.

Over the eons Billions of civilizations have probably come and gone

I don't know about that estimate, but it seems possible (maybe even likely) that civilizations have arisen at some point in parts of the universe. On this one planet alone we've had numerous civilizations rise and fall.

I dunno. I wonder what the comparative rates are for stellar creation vs stellar death.

We here on Earth are nothing my friends

Less than a speck of sand in the scheme of life.... oh well....

 

[johngaltshrugged]

I highly doubt there is other life in the universe, at least not as it may be portrayed by sci-fi.
The specific parameters that make life possible here on Earth are just too rare for it to be statistically likely.

I think there are other, non-human beings but these are extra-dimensional & would not qualify as true aliens from our time & space perspective.
These beings are the angels & fallen angels of the Bible & are most likely responsible for at least some of the UFO activity our govt now admits is out there & documented with no explanation.

I believe that ^^^^ would (or is) impossible to calculate.

Exactly. Even many secular researchers (including some well-known and respected ones) after decades of research concluded that so-called "aliens" are not extra-terrestrial, but extra-dimensional beings. And I'm glad that at least some of us know what they actually are.

Yes, and the Universe is Infinite.....it never ends.....which is totally beyond our understanding!

Awsome!

We may not be everything. But we're all we've got.

 

[skye]

We may not be everything. But were all we've got.

That's true too.

Maybe. I don't know. It seems to me that it can be observed to some extent. From there, it might be feasible to extrapolate the answer.

Maybe not precisely, but we can do this:

"The new study suggests that half of all stars that have ever existed were born in a boom between 11 billion and nine billion years ago, researchers said. Further, if the measured star-formation decline continues, then a maximum of 5 percent more stars will ever be produced — even if we wait forever."

Star Formation Sputtering Out Across the Universe

The rate of star formation in the universe has dropped to just 3 percent of its long-ago peak, and there's no end in sight to the decline, a new study finds.

Very cool link. The eternal question remains, who can create a vast universe from "nothing"?

A few "factoids" to consider:
1. The "big bang" spewed all of the energy in the universe thru an aperture about the size of an atom in an instant. All the galaxies cane from a spec of energy as it cooled.
2. "Time" didn't exist until the big bang
3. The universe is missing a lot of "anti-matter" where is it?
4. Was the universe formed by a reverse "matter/anti-matter" explosion so there is an "anti-matter universe" parallel with ours?
5. In about 100 trillion years the universe will be a cold empty space, which tends to agree with the "stars sputtering out" scenario.
