And either way, is energy or information conserved? When two things in the Universe that “always” occur meet one another, how do you know which one will win? Gravitational waves, […]
In 2006, Pluto was demoted in a very controversial decision. Unless you ignore nearly all of planetary science, it'll never be one again.
New research on ankle exoskeletons show promising results.
Life arose on Earth very early on. After a few billion years, here we are: intelligent and technologically advanced. Where's everyone else?
Is the “big freeze” our inevitable fate, or can dark energy save us? When we look out at the Universe today, we see sources of light practically everywhere we look. In […]
We’ve argued over ideology for far too long. It’s time to pick a better route to prosperity. In every civilized society around the world, there’s a trade-off that must be […]
Yet, if they only obey the rules that we know, there’s no way to explain why. One of the greatest puzzles in all of physics is that the laws of nature — as […]
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. […]
It happened more than once, and needed to. Here’s why. If there’s one thing you can be certain about when it comes to outer space, it’s that it’s transparent, not opaque, […]
Despite all the challenges, Hubble has vindicated this discovery. Practically everywhere we look in the Universe, the large-scale objects that we see — small galaxies, large galaxies, groups and clusters of galaxies, […]
Astrophysics has probed a test of a fundamental law, ‘Lorentz invariance,’ well beyond the LHC’s limits. Einstein is still right. The greatest scientific legacy that Albert Einstein left us is this: […]
We still don’t know how the information encoded onto it gets out. No matter what you do in the Universe, its overall entropy always increases. Even when we put things in […]
While Mars is known as a frozen, red planet today, it has all the evidence we could ask for of a watery past, lasting for approximately the first 1.5 billion […]
It doesn’t have to be a science-fiction dream. For as long as human beings have been watching the night sky, we’ve dreamed of visiting other worlds and truly seeing what’s […]
If there’s no phosphine, there’s no indirect evidence for biological activity there. In one of the biggest surprises in the history of planetary science, a September 2020 study announced the presence […]
Two stellar mass black holes, if they merge in the vicinity of a supermassive black hole, could have their gravitational wave signal affected by the strongly curved space around them. […]
Is that required for detectors like LIGO and Virgo to work? Whenever any two things in the Universe interact at the same location in spacetime, one thing always remains true about […]
As we embrace green solutions, nuclear should absolutely be part of the equation. For thousands upon thousands of years, humans have been harnessing the power of nature to provide energy […]
California’s Bobcat Fire has reached Mount Wilson Observatory’s doorstep. 100 years ago, our understanding of the Universe was very different from what it is today. Einstein’s General Relativity, our theory […]
It’s been called the biggest conundrum in all of cosmology, and recent measurements just add to the confusion. One of the most puzzling facts about the Universe is that different […]
It likely isn’t the rare occurrence we once thought it was. In our Solar System, there’s one overwhelming source of mass that all the planets orbit around: our Sun. Each planet […]
The neuralnanorobotics are coming.
