Sentences with phrase «of eternal inflation»

Weinberg isn't sure it would even be possible to tell the difference between these different possibilities, especially because many models of eternal inflation exist.

Rachel Courtland reports that a paradox exists in the theory of eternal inflation, which gives rise to the multiverse, because...

And if this idea of eternal inflation producing an infinite number of universes is right, those infinite number of universes could each have a different one of these 10500 vacua, so all of them would exist.

Instead, Guth suggests the paradox could just be an artefact of the measurement technique, since the exponential nature of eternal inflation means that newer universes will always be more common than older ones.

Should this minute realm contain just a smattering of repulsive - gravity material, that's enough to ensure it will ignite the unstoppable process of eternal inflation, leading to the universe we inhabit today.

A full theory of eternal inflation came together in Carroll's mind in 2004, while he was attending a five - month workshop on cosmology at the University of California at Santa Barbara's famous Kavli Institute of Theoretical Physics with his student Jennifer Chen.

Hertog told Cambridge that the physics that would account for infinite parallel universes break down when applied to the theory of eternal inflation.

«The usual theory of eternal inflation predicts that globally our universe is like an infinite fractal, with a mosaic of different pocket universes, separated by an inflating ocean,» Hawking said in an interview last fall, according to the University of Cambridge.

«When we trace the evolution of our universe backwards in time, at some point we arrive at the threshold of eternal inflation, where our familiar notion of time ceases to have any meaning,» Hertog told Cambridge.

Not exact matches

@Chad «the really fascinating aspect of Alexander Vilenkin Kinematic Incompleteness Theorem (the Borde Guth Vilenkin Theorem) is that not only demonstrates that OUR universe had a beginning, but it goes further to demonstrate that ANY universe (Multi-verse, Eternal Inflation, Cyclic Evolution, and Static Seed (Emergent Universe), etc.) that has a Hubble expansion greater than zero had a beginning.»

That inflation has now swayed the consensus before do not exclude that there is a high degree of dilution in LCDM, which is correct since 2004, whether or not you refer to ekpyrotic scenario (now in high stress) or chaotic / eternal inflation.

In the late 1980s Guth and other physicists, most notably Andrei Linde, now at Stanford, saw that inflation might happen over and over in a process of «eternal inflation.»

Some physicists have long embraced the notion that the extra dimensions of string theory play a key role in shaping the properties of new universes spawned during eternal chaotic inflation.

The same process will occur in each of those new universes in turn, a process Linde calls eternal chaotic inflation.

Those laws govern the something - from - nothing moment of creation that gives rise to our universe, and they also govern eternal inflation, which takes over in the first nanosecond of time.

If we assume inflation is eternal into the past — that it had no beginning — the space traveler will eventually reach and overtake the speed of light.

By 1982, a couple of years after Guth's breakthrough, Vilenkin had a realization of his own: The process of inflation had to be eternal, meaning that once it started, it never fully stopped.

As Vilenkin saw it, inflation's eternal nature stemmed from two competing properties of the cosmic fuel, the gravity - repulsive material that caused the universe to rapidly expand.

«If you don't like the cut - off, then you have no way of making predictions and deciding what's probable in eternal inflation.»

If the no - copy assumption is false, then there's no fundamental reason why there can't be copies of you elsewhere in the external reality — indeed, both eternal inflation and unitary quantum mechanics provide mechanisms for creating them.

It's quite common for mathematical equations to have multiple solutions, and as long as the fundamental equations describing our reality do, then eternal inflation generically creates huge regions of space that physically realize each of these solutions.

All of these universes are believed to come into existence through a process called eternal inflation, in which at least one universe continually expands at an incredible rate, while others form and grow within it like bubbles.

One model of inflation, called eternal inflation, suggests that new universes are continually popping into existence and expanding.

An interesting feature of inflation is that almost all versions of it lead to eternal inflation: once inflation starts, it goes on forever, producing a «multiverse» of «pocket universes,» one of which would be our universe.

A multiverse model tied to eternal inflation could have the same kind of explanatory power.
