Water In Our Universe -- Until comparatively recently, astronomers believed that the abundance of Water in our Universe arose relatively late in the Universe’s evolution, but recent research suggests that the first water molecules formed as early as one billion years after the Big Bang.
Should the Higgs boson have caused our Universe to collapse? Our Universe lies in a ‘valley’, which sets the behaviour of the Higgs boson. A deeper valley also exists, but our Universe is prevented from entering it by a large ‘hill’. During the early period of cosmic inflation, the BICEP2 results imply that the Universe would have received a ‘kick’ into the other valley, causing it to collapse in less than a second.
Is there more than one universe? In this visually rich, action-packed talk, Brian Greene shows how the unanswered questions of physics (starting with a big one: What caused the Big Bang?) have led to the theory that our own universe is just one of many in the "multiverse."
A visualization of an Einstein-Rosen bridge. In the article that this comes from, it is suggested that our universe is in one. That is, our universe could be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe.
