It hasn’t happened yet in the entire Universe, not even once. “End? No, the journey doesn’t end here. Death is just another path, one that we all must take. The grey […]

The Earth is round, Kyrie Irving. But not every world needs to be. “‘I’ll follow him to the ends of the earth,’ she sobbed. Yes, darling. But the earth doesn’t have […]
The red planet once wasn’t so different from Earth. Here’s what happened. “Mars’ atmosphere is so thin, you do not need a lot of streamlining. By the time the ship […]
There’s a lot to learn about other worlds, but you can’t learn it all without looking up. “One should not need a teleportation device to decide whether a newly discovered object […]
Colonizing Mars is a romantic notion but if it was possible, how would our bodies hold up and how would future generations evolve on a lower-gravity planet?

They move at the speed of light, but not even light can escape. So how do gravitational waves? “I think there are a number of experiments that are thinking about […]
Few see how strongly science’s preferred languages shape and limit the thinking of many experts.
One of inflation’s co-founders lashes out against the community. But is there a scientific leg to stand on? “…an understanding of the infinite tree of universes seems to be needed in […]
One of the fathers of string theory proposes a new equation that may reconcile general relativity and quantum mechanics.
Before the Big Bang… after the Big Freeze… will everything look the same? “What is wild cannot be bought or sold, borrowed or copied. It is. Unmistakeable, unforgettable, unshamable, elemental as […]
Images credit: New York Times, 10 November 1919 (L); Illustrated London News, 22 November 1919 (R). If the cloud situation had played out differently, the United States might have confirmed […]
Albert Einstein was the first to discuss the fabric of space, and according to his theorems, the curvature of it. We have been discussing the possibility of gravitational waves ever since.

If the Big Bang happened and everything is moving away from us, where’s the center? “I want to stand as close to the edge as I can without going over. Out […]
Will this EU power be the first to prove that a modern, industrialized nation can make major shifts towards cleaner, greener energy without catastrophe?
With gift ideas from as little as $11, there might be something to tickle anyone’s fancy. “It is worthy of notice that in Table VI the brighter variables have the longer […]
And succeeds! “Faced with the choice between changing one’s mind and proving that there is no need to do so, almost everybody gets busy on the proof.” –J. K. Galbraith One […]
Sorry to all you ‘Flash’ fans out there; it’s not reality yet. This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and high energy […]
But that’s okay; the most likely world for life may not be like Earth, after all. “You can spend too much time wondering which of identical twins is the more alike.” […]
Newton thought it was instantaneous, but the story is much richer than that! “The fact that gravitational damping is measured at all is a strong indication that the propagation speed of […]
How far are you willing to trust technology? Make a call, share a photo, find a good restaurant, pay a bill, vacuum the floor? But, will you trust autonomous systems with your life and the life others? Autonomous vehicles will be making decisions for us at 60mph and more — the question facing us may no longer be technological but social. How much do you trust a robot?
And, in the process, surpasses every supernova ever seen in terms of brightness. “Even with all the collected data we cannot say with 100% certainty that the ASASSN-15lh event was […]
Each might be as heavy as an asteroid and as tiny as a decimal point.
How a telescope 100 times the size of Hubble is going to change everything. “For my confirmation, I didn’t get a watch and my first pair of long pants, like […]
In Netflix’s “Stranger Things” characters enter a parallel dimension. Could this actually happen?
That’s not how probability works. Or asteroids, for that matter. “Bringing an asteroid back to Earth? What’s that have to do with space exploration? If we were moving outward from there, […]
With James Webb and WFIRST launching soon, the Universe can expect a revolution. But what will it look like? “For the first time we can learn about individual stars from near […]
The Perseid meteor shower is coming, which may put you in the mindset to wonder “What causes a meteor shower?”
It’s the most mysterious “stuff” our Universe has. So why are we so sure it’s real? “The Universe is made mostly of dark matter and dark energy, and we don’t know […]
We have every reason to believe gravity is an inherently quantum theory. Here’s how we’ll prove it once and for all! The following article was written by Dr. Sabine Hossenfelder. Sabine […]
