The most incomprehensible thing about the universe is that it is comprehensible,” Albert Einstein once pondered. But even as ...

We found that 99.5% of them would experience a larger dark energy density than observed in our universe. In other words, it ...

Our Universe appears perfectly spatially flat, with the initial total energy density and the initial expansion rate balancing one another to at least some 20+ significant digits. Ned Wright's ...

The Fate of the Universe. What kind of universe we live in matters a great deal, and not just when it comes to beams of light. The density and shape of the universe could determine how it will ...

But, considering a multiverse wherein each universe contains a different dark energy density—observed by one intelligent observer—the team found that 99.5 percent of these universes boasted a ...

The chances of intelligent life emerging in our universe—and in any hypothetical ones beyond it—can be estimated by a new theoretical model which has echoes of the famous Drake Equation.

Open and Closed Universes ... The blue rings illustrate motion in a universe with high density. In this case, the expansion began later but was initially much more rapid.

So here is where we are: a flat, critical-density universe comprising ordinary matter at about 5 percent, particle dark matter at about 25 percent, and dark energy at about 70 percent.

Clockwise from the upper-left panel: no dark energy, same dark energy density as in our universe, 30 and 10 times the dark energy density in our universe. Credit: Courtesy of Oscar Veenema, former ...

Parallel universes with additional dark energy could have more stars than our universe, which increases the chance of alien life developing. (This image shows a stellar nursery in the Large ...

We found that 99.5% of them would experience a larger dark energy density than observed in our universe. In other words, it looks like we inhabit a rare and unusual universe within the multiverse.
