It Seems More and More Certain That We Live in a Multiverse

  1. Last week, physicists announced that they'd discovered evidence of gravitational waves in the early universe, which makes it more likely that our universe began with a bangand inflated from there. But that also means a whole host of other things, including possible multiverses.

    Physicist Sean Carroll has a deft article in the New York Times that explains the greater significance of last week's announcement. Carroll notes that work done by physicist Alan Guth suggests that the early universe was full of a type of energy dubbed "the inflaton," which pushed space apart. But eventually this inflaton converted into matter, which tends to coalesce under gravity. Still, we have to wonder — if all the inflaton settled down into matter, why is the universe still expanding? Could something else have happened to the inflaton?

    Writes Carroll:

    Soon after Guth proposed inflation, the physicists Alexander Vilenkin and Andrei Linde pointed out that the process of inflation can go on forever. Instead of the inflaton energy converting into ordinary particles all throughout the universe, it can convert in some places but not others, creating localized "Big Bangs." Elsewhere inflation continues, eventually producing other separate "universes," eventually an infinite number. From an attempt to explain conditions in the single universe that we see, cosmologists end up predicting a "multiverse."

    This may sound like a very peculiar result. But in the news conference after last week's announcement, both Guth and Linde suggested that evidence for inflation boosts the case for the multiverse.

  2. 1st nice copy and paste and 2nd This has kinda been self-evident through out life i mean big gas clouds, massive balls of energy and other masses that's like saying fishes weren't born in water. Not surprised.
     
  3. Does this mean other universes where there may exist nothing except empty space (or planets, or stars, or even organic life that may have come to form on it's own by happenstance), or does it mean the more science fiction-like idea where for everything in the entire universe that could be different (even on the most miniscule level), there's a universe out there where things are that way? (For example, a universe where everything that's ever happened and ever will happen in this present one is the same, except my name happens to be Bob instead of Kevin.)
     
  4. You're supposed to copy and paste as long as you provide a source.
     
  5. Meh, science is too complicated and self contradictory. Within a couple months, we'll see something about us living in andromeda instead for all we know.
     
  6. Does that mean someone can actually be The One!? Cause I'll gladly murder my other selves for the powah! Bwahahahaha
