Kinda makes you go hmmmm.
One of the biggest mysteries in cosmology could be explained by a controversial theory in which the universe explodes into existence not just once, but repeatedly in endless cycles of death and rebirth.
Called the cyclic universe theory, it could potentially explain why a mysterious repulsive form of energy known as the “cosmological constant,” which is accelerating the expansion of the universe, is several orders of magnitude smaller than predicted by the standard Big Bang model.
Now, I’ve never been a fan of the traditional Big Bang Theory. It just has too many practical holes. The one that bothers me most is the question of what was there before the big bang? Something had to be. You just don’t normally get something from nothing. So, a LONG time ago, I came up with the cyclic theory. Now, apparently it’s catching on.
But, that still doesn’t explain what was there before the first one.
The blast originated about 50,000 light-years away and was detected Dec. 27. A light-year is the distance light travels in a year, about 6 trillion miles (10 trillion kilometers).
“Had this happened within 10 light-years of us, it would have severely damaged our atmosphere and possibly have triggered a mass extinction,” said Bryan Gaensler of the Harvard-Smithsonian Center for Astrophysics (CfA).
Dang, as usual. I totally missed it. Definitely click on the link and read the whole story. It’s an interesting read in its entirety. What’s cool to think about IMO, is that something so far away could have an impact on Earth. The universe just gets smaller every day.
That sand is a close-up from Hubble of Spiral Galaxy NGC 300. Every single one of those grains of sand is a star. Every single one of those stars likely has some planets orbiting it. Still think we’re alone?
