Two parts of our Universe that seem to be unavoidable are dark matter and dark energy. Could they really be two aspects of the same thing?
It is time to give the Russian cosmologist the credit he deserves.
This afternoon, the Supreme Court agreed to hear argument in two same-sex marriage cases: a challenge to the U.S. 9th Circuit Court of Appeals decision to overturn Proposition 8 and […]
In response to a growing number of visitors along with recent city ordinances restricting or eliminating on-street parking, some parking garage owners are turning to smartphone technology.
Why the best CEOs make their first year both a personal transition and a profound moment of institutional renewal — with this quartet of skills.
As we gain new knowledge, our scientific picture of how the Universe works must evolve. This is a feature of the Big Bang, not a bug.
In “On Liberalism," Cass Sunstein argues that liberalism can only endure if we reclaim its core commitments and revive its spirit of freedom and hope for the future.
It's the origin of our entire observable Universe, but it's still not the very beginning of everything.
Just 13.8 billion years after the hot Big Bang, we can see 46.1 billion light-years away in all directions. Doesn't that violate...something?
If you want to understand the Universe, cosmologically, you just can't do it without the Friedmann equation. With it, the cosmos is yours.
Here in our Universe, time passes at a fixed rate for all observers: one second-per-second. Before the Big Bang, things were very different.
The fact that our Universe's expansion is accelerating implies that dark energy exists. But could it be even weirder than we've imagined?
Since 1998, we've known our Universe isn't just expanding, but the expansion is accelerating. Could the Big Bang itself be the reason why?
Perhaps no existential question looms larger than that of our ultimate cosmic origins. At long last, science has provided the answers.
Einstein's general relativity has reigned supreme as our theory of gravity for over a century. Could we reduce it back down to Newton's law?
First discovered in the mid-1960s, no cosmic signal has taught us more about the Universe, or spurred more controversy, than the CMB.
An evidence-based policy movement is arming the fight with tools and programs that are more effective than ever before.
For nearly 60 years, the hot Big Bang has been accepted as the best story of our cosmic origin. Could the Steady-State theory be possible?
Since the mid-1960s, the CMB has been identified with the Big Bang's leftover glow. Could any alternative explanations still work?
Almost everyone asserts that the Big Bang was the beginning of everything, followed by inflation. Has everyone gotten the order wrong?
Today, the deepest depths of intergalactic space aren't at absolute zero, but at a chill 2.73 K. How does that temperature change over time?
In all directions, at great distances, the Universe looks younger, more uniform, and less evolved. Does that mean Earth must be the center?
The Universe isn't just expansion, but the expansion itself is accelerating. So why can't we feel it in any measurable way?
The Universe is 13.8 billion years old, going back to the hot Big Bang. But was that truly the beginning, and is that truly its age?
Many contrarians dispute that cosmic inflation occurred. The evidence says otherwise.
The big question isn't whether the Universe is expanding at 67 or 73 km/s/Mpc. It's why different methods yield such different answers.
While the concept stretches back centuries, it has garnered significant attention in recent decades.
Just 13.8 billion years after the hot Big Bang, we can see objects up to 46.1 billion light-years away. No, this doesn't violate relativity.
“Isn’t it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?”
The Universe is precisely dated at 13.8 billion years old, but astronomers claim the Methuselah star is 14.5 billion years old. What gives?
