For just a year’s worth of US Military budget, we could transform the world. The United States spends more on military spending than the next ten nations combined: an estimated $600 […]
What we think of as our average region of the Universe might not be average at all. “No matter what technique you use, you should get the same value for the […]
Dark matter, dark energy, and why there’s more matter than antimatter? There’s an experiment to explore if neutrinos could solve all three. When you take a look at the Universe in […]
With a journey of 130 million light years, both signals should move at the speed of light. So why did one get here first? On August 17, after a journey taking […]
Even if you have a problem with the messenger, you still need to heed the message. “Whether humans are responsible for the bulk of climate change is going to be left […]
No matter what the science says, there’s no excuse for cruel behavior to a colleague. Look out into the distant Universe as far as you possibly can, and you’ll come […]
Go back to school, Agora style. Philosophy can train us to respond to life’s problems rather than merely react. One such training camp is coming to Baltimore.
Get lost in a good book. Time and again, reading has been shown to make us healthier, smarter, and more empathic.
Should Jon Snow go to Dragonstone? Should Samwell “operate” on Ser Jorah? The line between intuition and foolishness can only be drawn in hindsight.
We’ve come so far since 2015; what do we know about dark matter now that we didn’t know then? Back in 2015, the dark matter situation was pretty straightforward: the large-scale […]
How looking at a single, distant galaxy cluster can show us the invisible mass filling our space like nothing else. “We find them smaller and fainter, in constantly increasing numbers, and […]
Before we go venturing off to another star to look for life, why not look here? “If I had to describe myself to an alien I’d say I was bigger than […]
If we see an atomic nucleus decay in a particular way, it means the Universe is fundamentally different from how we see it today. “There are several categories of scientists in […]
For those who still don’t believe in global warming, the science has had it right for half a century now. “Greenhouse gases are the second most important factor for climate, after […]
From 13.4 billion years ago, the current record-holder is unlikely to fall anytime soon. Why? A combination of science… and luck. “We’ve taken a major step back in time, beyond what […]
If you thought our galaxy was just the luminous matter within it, think again. “Things need not have happened to be true. Tales and adventures are the shadow truths that […]
When you’re confronted by some new information, how do you tell whether it’s valid or not? “I’m old enough to remember when the polio vaccine was still new. Also, it hadn’t […]
It’s durable, exponentially scalable, and it’ll last millennia, if not millions of years.
If you think we’ve seen all there is to see in the Universe, you’re about to have your imagination unlocked. “Hubble often takes images of distant gravitationally lensed galaxies to […]
There’s a smallest scale and a shortest time at which physics makes any sense. What sets that limit? “There is a limit on how much information you can keep bottled up.” –Dick […]
The event horizon is real, and we know it without even needing to see it directly. “Where we’re going, we won’t need eyes to see.” –Sam Neill, Event Horizon If […]
How gravitational magnification allows us to see what we’ve never seen before. “The problem is, you’re trying to find these really faint things, but you’re looking behind these really bright things. […]
When a phenomenon moves from “empirical correlation” to “theoretically explained,” that’s one of the biggest deals in science! “Space and time may have a structure as intricate as the fauna of […]
Astrobiologist Lewis Dartnell explains why we shouldn’t be afraid of alien visitors.
If even black holes won’t last forever, what will happen when the last one goes? “My discovery that black holes emit radiation raised serious problems of consistency with the rest of […]
Meet LISA, the Laser Interferometer Space Antenna. Yes, it’s giant LIGO, in space, and it’s happening! “Einstein’s gravitational theory, which is said to be the greatest single achievement of theoretical […]
When galaxy clusters merge together, they form the largest objects the Universe will ever create. “On a cosmic scale, our life is insignificant, yet this brief period when we appear in […]
You might think Jupiter is large, but you’ll be surprised at what happens if you try and make it larger! “A few centuries ago, the pioneer navigators learnt the size and […]
