Is It Time to Accept That We're Alone in the Universe?

We have yet to discover any signs of aliens, a troubling observation that has led to much speculation. One possible solution to the Great Silence is that nobody's out there.

It's Looking More and More Likely That We Live in a Multiverse

Could our massive universe be just one of many, like a bubble in a frothy stream of cosmos-spawning stuff? It sounds like something out of a 1970s British scifi novel, but it's become a popular explanation for the origin of our universe. But how can we test this hypothesis, when we're stuck in just one universe? » 11/03/14 3:20pm 11/03/14 3:20pm

​What If Dark Matter Were Actually A Vast Electric Field?

There isn't enough visible matter in the universe to account for the gravitational force that holds galaxies together. That's why scientists are searching for evidence of the missing "dark matter" that makes it possible. Now, one researcher has advanced an odd theory: dark matter is actually a galactic-scale electric… » 11/03/14 1:40pm 11/03/14 1:40pm

Curious Signal Could Be Dark Matter Pouring From The Sun's Core

This could be historic: Astronomers from Leicester University have detected a strange signal in the X-ray spectrum that appears to be a signature of 'axions' — a hypothetical dark matter particle. It could take years to confirm, but this may be the first direct detection and identification of dark matter. » 10/17/14 8:00am 10/17/14 8:00am

A 19th Century Math Genius Taught Us The Best Way To Hold Pizza

We've all been there. You pick up a slice of pizza and you're about to take a bite, but it flops over and dangles limply from your fingers instead. The crust isn't stiff enough to support the weight of the slice. Maybe you should have gone for fewer toppings? No. There's no need to despair. » 10/10/14 9:30am 10/10/14 9:30am

What Lit Up The Universe? Astronomers May Be On The Brink Of An Answer

Most scientists can see, hear, smell, touch or even taste their research. But astronomers can only study light — photons traveling billions of light-years across the cosmos before getting scooped up by an array of radio dishes or a single parabolic mirror orbiting the Earth. » 8/28/14 9:20am 8/28/14 9:20am

How Would Christianity Deal with Extraterrestrial Life?

How would the world's religions react to the discovery of extraterrestrial intelligence? There is, of course, no single answer. But for Christians who believe in the redemption of humanity through a singular event—the Incarnation of God through Christ—the question poses an especially complex dilemma. » 7/24/14 10:07am 7/24/14 10:07am
