Scientists find evidence of a 'former universe'

Physicists have found what could be evidence of 'ghost' black holes from a universe that existed before our own.
The remarkable claim centers around the detection of traces of long-dead black holes in the cosmic microwave background radiation - a remnant of the birth of our universe.

According to a group of high-profile theoretical physicists including Oxford's Roger Penrose, these traces represent evidence of a cyclical universe - one in which the universe has no inherent end or beginning but is formed, expands, dies, then repeats over and over for all eternity.

"If the universe goes on and on and the black holes gobble up everything, at a certain point, we're only going to have black holes," Penrose told Live Science. "Then what's going to happen is that these black holes will gradually, gradually shrink."

When the black holes finally disintegrate, they will leave behind a universe filled with massless photons and gravitons which do not experience time and space.

Some physicists believe that this empty, post-black hole universe will resemble the ultra-compressed universe that preceded the Big Bang - thus the entire cycle will begin anew.

If the cyclical universe theory is true, it means that the universe may have already existed a potentially infinite number of times and will continue to cycle around and around forever.

Who knows - perhaps each of us has also lived countless former existences as well.

Thinking about this is scary, lol !The value of space and time are so big that our puny human mind have difficulties to cope with it !

I feel a sad truth that these things out there and beyond are not for me or you. But we will put forth all our earthly understanding and application to stake providence.

I'm probably wrong, but I keep thinking of there being an infinite, void container and also a content that is attempting to fill that container by continuously expanding.   Seems to me that if a black hole sweeps all the rest of the contents into itself the container is capable of continuing to exist as infinite, and the next big bag attempts to fill the container once again. In essence, the container is Nothing (empty space) and never joins anything to become an additional part of anything.

Maybe what you're saying is that a nothing must exist for something to exist within it?  I think "nothing" can exist, is a possible state of existence. I consider this because we can also postulate "not-nothing".  Whether "nothing" must exist for "something" to exist is umm... Does the existence of "something" require its opposite, "nothing" to exist? Like the various infinities, nothings can make the head spin. (The set of odd numbers is infinite, but also is the set of all natural numbers. If both sets are infinite, how can one set have twice as many numbers in it? Twice the infinite number ... [More]

More than 1 universe, more than 1 big bang?

It's so devastated that its last season is coming up.  I'm so happy!

What if black holes act like vacuum cleaners.  Once they gobble everything up, their "Bag" breaks and lets everything out with a "Big Bang"!  Of course all the black holes would have to pop at once unless there is a chain reaction started.  MAybe all the black holes connect to the same "Bag", like the houses that have in-wall vacuums in each room.  Guess I'm showing my age again as I haven't heard that one in a long, long time.

I am pleased I am not the only one to wondered that ....   Though my idea was that eventually one very massive black hole absorbed everything in the "local" part of the infinite universe until it burst, creating a "local" big bang ......   What we observe today is just the result of the most recent "local" big bang but there maybe be another one taking place this very minute.  A few trillion light years away.

Seems more likely that the 'evidence' points to proof of former black holes rather than proof of a former universe.

Futurama already posited this theory.
