The laws of physics aren’t changing. The Earth is. When it comes to any physical science, we know that the fundamental rules governing how the Universe works remain constant with time. […]

The Crab Nebula goes back to 1054, opening a window into our cosmic past. On July 4, 1054, Chinese astronomers recorded a “guest star” in the Taurus constellation. A ‘guest star’ […]
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
A single lifetime is more than enough to take you to the limits of the Universe. Right now, there are only three things limiting how far our spacecrafts can take […]
Enough mass in one location will always create a black hole. But not all masses are possible. If you take enough mass and compress it into a small enough volume […]
Deniers will never stop misleading others. Here’s the truth. Every so often, advocates of a fringe theory — one that doesn’t fit the evidence as well as the mainstream theory — do what they can […]
Even 13.8 billion years after the Big Bang, we can reconstruct the first 3 minutes. About 100 years ago, we began to truly understand the nature of the Universe for the […]
It’s how successful our current theories are. Some 500 years ago, there was one scientific phenomenon that was, without controversy, extremely well-understood: the motion of the celestial objects in the sky. […]
The definitive answer requires better, unbiased data. Despite all the advances that have occurred in human history, one extraordinary puzzle still remains right in our own backyard: we aren’t sure how […]
It’s not a gambit. It’s not fraud. It’s not an opinion. And it’s not biased like you think it is. Most of us, when we think about what science is, default […]
If we want our conclusions to be meaningful, our data had better be robust. When it comes to the Universe, there’s a whole lot that doesn’t add up. All the matter […]
What we’ve seen isn’t necessarily what we get, but the most common world doesn’t look like ours. There’s a very common myth out there in astronomy: the idea that the Sun […]
The Big Bang is our accepted origin of the Universe. But is there another possibility? Since the mid-1960s and the discovery of the Cosmic Microwave Background, the Big Bang has […]
Demanding appropriate levels of skepticism and scrutiny isn’t cruelty, but rather demonstrates scientific integrity and intellectual honesty. Every few months, a novel headline will fly across the world, claiming to […]
And what might we learn as we collect new, never-before-seen data? If you took one of history’s top scientists from 100 years ago and dropped them into today’s world, what […]
If Scotty beams you up for a trip around the Sun, here’s how to handle it. “I really didn’t have to work, shall we say, with Star Trek. It was a […]
Forwards? Absolutely. Backwards? Perhaps. Becoming your own grandpa? Only if you’re Philip J. Fry… “One of the great things about music is that it has the capability of time travel — you smell […]
With current technology, things might take generations. But that could be greatly reduced with a little help. “Oh, yes — I know you. There was a time you looked at the stars and […]
The fastest way to make interstellar travel a reality might not be only science fiction for long! It is humanity’s longstanding dream to venture to the stars. We long to […]
