bubbled» out from the black hole of another
universe or be the result of two or more larger dimensions colliding
with each other — we just don't know)
Inflation does not result in a
universe with uniform properties, but a multiverse
with an infinite number of «
bubbles» in which the cosmic and physical properties vary from
bubble to
bubble.
These
bubbles are «baby
universes,» and the holes are wormholes connecting our
universe with another parallel
universe.
Something like this could occur inside a black hole,
with a baby
universe forming as a tiny
bubble at the inner horizon.
Part three, «The Quest for Our Universal Destiny», delves into interesting but often speculative subjects, and ends
with discussions on topics such as everlasting life,
bubble universes and the meaning of it all.
It is certainly in principle possible for
bubble universes to collide
with each other.
A Type III civilization would be able to manipulate the Planck energy (1019 billion electron volts), the energy at which space - time becomes foamy and unstable, frothing
with tiny wormholes and
bubble - size
universes.
In more recent studies the
universe appears as a collection of giant
bubble - like voids separated by sheets and filaments of galaxies,
with the superclusters appearing as occasional relatively dense nodes.
a) A tangled ball of cosmic string b) A being that appears to be made out of pure energy, captain c) A
bubble of space that inflated out of sync
with the rest of the
universe d) A giant black hole whose gravity red - shifts light from that direction
NOMURA REPLIES: Regarding Kell's question: Because of the eternally inflating nature of the space in which our
bubble resides, the probability of our
universe colliding
with other
universes is almost certain.
If the constants vary from one
bubble universe to another, their local values can not be predicted
with certainty, but we can still make statistical predictions.
A detection of such a spot
with the predicted intensity profile would provide direct evidence for the existence of other
bubble universes.
No matter how fast we travel, we can not catch up
with the expanding boundaries of our
bubble, so for all practical purposes we live in a self - contained
bubble universe.
However, other research was starting to show that our
universe could actually survive a run - in
with an alien
bubble — and in fact, there was a good chance that such a nonlethal collision had already occurred.
He is quick to admit that a collision
with another
bubble universe is not the only possible explanation for the strange patterns seen by WMAP.
But he adds that even if
bubble universes exist, they might not form at a rate that would guarantee one would have collided
with our
universe.
In practice, normal and dark matter appear to fill the
universe with a foam - like structure, where galaxies are located on the thin walls between
bubbles, and are grouped into superclusters.
«If we wait long enough, our
bubble universe will eventually undergo an infinite number of collisions
with other
bubble universes,» Vilenkin says.
If our
bubble had collided
with another in the distant past, the smashup would have injected a huge amount of energy into a portion of our
universe.
is difficult to reconcile
with the obvious clumping of matter into galaxies, clusters of galaxies, and even larger features extending across vast regions of the
universe, such as «walls» and «
bubbles».»
For example, in
Bubble universe theory, there are an infinite variety of «
universes», each
with different physical constants.
