What happens if the density of dark energy page 85
increases the universe grows? Or, we could
ask: What happens if the quantity of dark energy in the
universe grows more quickly than the expansion of
the universe itself? Even the bonds in atoms
blink (v.):
would break in just the blink of an eye before parpadeo
the universe tears itself apart.
Of course, there is no good reason for us, individually, to
worry about the universe ending. The Big Change scenario
might be an exception, but all of these possibilities occur
trillions of years in the future, so they shouldn’t keep you
up at night. Also, there’s no reason to fear for humanity. But
could any kind of intelligent, aware creatures survive?
A solution has been proposed by some physicists, it really
sounds like a mad scientist’s theory. To survive the end of
the universe, their solution is to build our own universe in a
laboratory, and hop on in. Alan Guth of MIT in Cambridge,
Massachusetts is one of the physicists working on this idea.
“I can't say that the laws of physics absolutely imply that
it's possible,” says Guth. “If it is possible, it would require
technology vastly beyond anything that we can foresee. It
would require huge amounts of energy that one would need
to be able to obtain and control.”
Guth also points out the end of the universe is not the only
possible outcome. He believes that there is a multiverse in
which there are more “pocket universes” like ours. So the
universe we inhabit is just one little piece of a multiverse.
“If that's the case, even if we’re convinced that an individual
pocket universe will ultimately die, the multiverse as a whole
will go on living forever, with new life being created in each
pocket universe as it's created,” says Guth. “In this picture,
the multiverse as a whole is genuinely eternal.
