Human evolution, solar flares, and the Big Bang all made headlines this week. But did you miss the news? Don't worry -- I was able to count down th...

Imagine you could go back 13.8 billion years to the dawn of time. What do you think you would hear during the Big Bang? We may not have time machines ...

PARIS -- A new examination of what is essentially the universe's birth certificate allows astronomers to tweak the age, girth and speed of the cosmos,...

Unlike scientific claims, beliefs cannot be arbitrated to determine which is valid because there is no objective basis on which to compare one set of beliefs to another. Those two world views are not closer than we think; they are as far apart as could possibly be imagined.

Given that the different members of the multiverse are not causally connected, the question that emerges is whether there is a way to verify whether such a multiverse truly exists. As it turns out, there are at least two possible paths that could (at least in principle) test the multiverse scenario.

Cosmologists have used the Big Bang theory to examine how the large-scale structure of the universe emerged from tiny fluctuations in the density of cosmic matter -- but the original model left some perplexing cosmic properties to chance.

I'm convinced that most readers have at least heard that we believe our universe started with a "Big Bang" -- a very hot and dense state. Why do we think that?

It's enough to make you alternately laugh and cry. But this daffy performance speaks to a problem even larger than Broun's dreadful ignorance. Why is this gentleman in Congress at all?

While the "why" part may elude us, perhaps forever, the Large Hadron Collider has over the last six weeks already supplied us with two important pieces of information about the "where" and the "how." Physicists tell us that this is just the beginning.

Imagine looking back in time--no, not flipping through old high school yearbooks--but really, studying the history of our universe as it was 13.7 bill...

There are at least two crucial circumstances in which we absolutely need a theory in which general relativity and quantum mechanics are compatible. One is the case of the objects we call black holes, and the second is the Big Bang.

Have you ever wondered what happens at the center of a black hole? Is it simply a dense, hot core filled with crushed matter? Is there such a place as...
