THE curtain at the edge of the universe may be rippling, hinting that theres more backstage. Data from the European Space Agencys Planck telescope could be giving us our first glimpse of another universe, with different physics, bumping up against our own.
Thats the tentative conclusion of an analysis by Ranga-Ram Chary, a researcher at Plancks US data centre in California. Armed with Plancks painstaking map of the cosmic microwave background (CMB) light lingering from the hot, soupy state of the early universe Chary revealed an eerie glow that could be due to matter from a neighbouring universe leaking into ours.
This sort of collision should be possible, according to modern cosmological theories that suggest the universe we see is just one bubble among many. Such a multiverse may be a consequence of cosmic inflation, the widely accepted idea that the early universe expanded exponentially in the slimmest fraction of a second after the big bang.
Once it starts, inflation never quite stops, so a multitude of universes becomes nearly inevitable. I would say most versions of inflation in fact lead to eternal inflation, producing a number of pocket universes, says Alan Guth of the Massachusetts Institute of Technology, an architect of the theory.
Energy hidden in empty space drives inflation, and the amount thats around could vary from place to place, so some regions would eventually settle down and stop expanding at such a manic pace. But the spots where inflation is going gangbusters would spawn inflating universes. And even areas within these new bubbles could balloon into pocket universes themselves.
Like compositions on the same theme, each universe produced this way would be likely to have its own spin on physics. The matter in some bubbles the boring ones would fly apart within 10-40 seconds of their creation. Others would be full of particles and rules similar to ours, or even exactly like ours. In the multiverse of eternal inflation, everything that can happen has happened and will probably happen again.

I know that is our universe because Dick Cheney is allowed to roam free.
I thought I had seen every Star Trek episode back when we only had three channels. But don't remember this one.

(7,865 posts)Which probably means I should question it.
Still, the occurence of other "big bangs" makes the event a repeating, non-singular event, which was my biggest problem with the big bang in the first place.

(3,829 posts)but you are right about it not being a singular event. It would be impossible for the big bang to come from of nothing, since nothing can't producing anything. Plus nature doesn't produce things in ones. A single big bang would be impossible.
Nature has order and is predictable. If things only happen in ones, that would destroy science. But science does work.

From the speech
The Importance of Human Beings
Every model of the universe has a hard swallow. What I mean by a hard swallow is a place where the argument cannot hide the fact that theres something slightly fishy about it. The hard swallow built into science is this business about the Big Bang. Now, lets give this a little attention here. This is the notion that the universe, for no reason, sprang from nothing in a single instant. Well, now before we dissect this, notice that this is the limit test for credulity. Whether you believe this or not, notice that it is not possible to conceive of something more unlikely or less likely to be believed! I mean, I defy anyone its just the limit case for unlikelihood, that the universe would spring from nothing in a single instant, for no reason?! I mean, if you believe that, my family has a bridge across the Hudson River that well give you a lease option for five dollars! It makes no sense. It is in fact no different than saying, And God said, let there be light. And what these philosophers of science are saying is, give us one free miracle, and we will roll from that point forward from the birth of time to the crack of doom! just one free miracle, and then it will all unravel according to natural law, and these bizarre equations which nobody can understand but which are so holy in this enterprise.

"What" happened isn't really much in doubt. "Why" it happened and what was going on "before" (a meaningless term since time wasn't the same); lots of room for conjecture there, since the Big Bang is the origin of what we can observe.
Looking at ripples at the edge of the universe is cool because it has the potential to let us see evidence of "before".

So long as the nothing gets paid back so to speak no biggie.
The universe will eventually go back to nothingness as the last particles decay...it's just going to take a really long time, but eventually it will pay back that debt.

which inevitably leads to the conclusion that all of our conscious-selves will be repeated an infinite number of times, and will always exist, in a multiverse in infinite size and time. So reincarnation must happen, except there is no soul and memories are destroyed each time you die.
It would be impossible to only exist in a single finite period of time in an infinite (in time) multiverse, since a finite number divided by an infinite number equals zero (finite #/infinite # = 0), which would be the chances of living at a particular period of time in an infinite universe (or multiverse). In an infinite multiverse (in size) each conscious-self must always exist, since everything that is possible must always exist.
