Title: Are we living in a metastable universe?
Post by: PopeyesPappy on February 19, 2013, 12:10:16 AM
Observations on the mass of the top quark and Higgs particle candidate are leaning that direction. If it is true, our universe could be relatively short lived.

well - in all fairness - this^ article did say "at some point, billions of years from now..."
which sounds feasible to me.  I mean........  "billions of years from now"  --- right?

Or should I pack a bag?

Interesting stuff.  I've always been a little worried that the vacuum might not be as stable as it looks.

The other worrying thing is that it might have happened already.

In the cosmic scheme of things this would probably be better than some of the alternatives like getting fried by a gamma ray burst.

I remember my brother was worrying about the whole 2012 shill, because that's all people in prison could do at the time apparently. I reassured him that according to some physicists the reality is kind of like a bubble, and could "pop" at any moment leading to total nonexistence.  Somehow that did not quell his fears.

Sun burns out in 4.5 billion years? Oh geez, so much to do, so little time.

I'm interested in this due to its possible implications to the cyclic universe hypothesis.

If it's expanding towards us at the speed of light, our sun might still burn out before it reaches us. Depending on how long ago it happened and where it started. I can't think of any theoretical way to get an early warning on an event headed toward you at the speed of light, but it would be nice if we can figure one out.

I wouldn't worry about it. We'll never know what happened. POOF!!

Don't worry Strom. In 10^10^10^10^10^1.1 years none of this will matter anyway.

Maybe it's already happening. Remember dark flow?
Or maybe that's just another universe we ran into. Our bubble is deflating.

Fun stuff.
