Revised Cosmological Constant Predicts a Collapsing Universe

The going theory among cosmologists is that the universe will eventually rip itself to shreds owing to its ever-accelerating rate of expansion. Not so, say a pair of physicists who have just taken it upon themselves to reformulate an integral facet of general relativity: the cosmological constant. » 3/07/14 2:46pm 3/07/14 2:46pm

We might be destroying the universe just by looking at it

It's not often that astronomy goes well with the book of Genesis. But this is a theory that evokes the line, "But of the tree of the knowledge, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die." In this theory, knowledge doesn't just kill you — it kills the entire universe. Indeed,… » 2/03/14 11:19am 2/03/14 11:19am

The Objects in Space That We Really, Really Can't Explain

Forget UFOs — there are a lot of objects and events in space that are identified, but still completely incomprehensible. From planets in our solar system, to inexplicable energy bursts from across the universe, here are some of the enduring mysteries of the space and time we call home. » 1/02/14 1:40pm 1/02/14 1:40pm

How red light revealed that the Universe is expanding

We have known for some time that the universe is expanding, and that its expansion is accelerating. But how do we know that? We'll show you how Edwin Hubble revealed that the universe is getting away from us. » 9/11/13 1:44pm 9/11/13 1:44pm

Is there a link between the Higgs boson and dark energy?

The Universe is expanding at an accelerating rate and we’re not entirely sure why. To deal with the problem, scientists have conjured up dark energy, a mysterious force that permeates all of space. Now, a pair of physicists say the newly discovered Higgs boson could help explain where it all comes from. » 8/12/13 12:30pm 8/12/13 12:30pm

Einstein may have discovered dark energy without even realizing it

An historian of science from New York University has re-interpreted a correspondence between Albert Einstein and Erwin Schrodinger in which the two scientists argued about the nature of the cosmological constant — a kluge that Einstein embedded in his general theory of relativity to explain why the Universe was… » 12/04/12 12:00pm 12/04/12 12:00pm

Dark Energy Confirmed: How ancient sound waves shaped the entire…

Just 30,000 years after the Big Bang, the universe started singing. Vast soundwaves rang out and expanded through the primordial cosmos, their ripples determining the universe's large-scale structure. And this all fits perfectly with one particularly theory of dark energy. » 4/03/12 3:09pm 4/03/12 3:09pm

Why is the universe pointing in one direction?

While the faster-than-light neutrinos are grabbing all the physics-shattering attention, there's another strange, unexplained anomaly that might be about to rewrite our understanding of the cosmos. It's all because the universe isn't as monotonous as it should be. » 12/11/11 2:25pm 12/11/11 2:25pm

Gigantic gravitational waves could explain the universe's biggest…

Modern physics assumes the universe is the same all over... but that might not be the case. Until recently, physics held that the universe was contracting... now we're stuck with dark energy. But one moderately insane new theory could explain it all. » 9/27/11 4:00pm 9/27/11 4:00pm
