It really is the ‘glue’ that holds the Universe together, enabling structures like our own galaxy to form in the first place. One of the most puzzling and counterintuitive facts about […]

To find the optimal route between many different locations, we need the power of quantum computers.
The darkness of the night sky was a mystery for generations of humans. Here’s the reason why. From our perspective here in the Solar System, it makes absolute intuitive sense why […]
As time goes on, every galaxy beyond our local group will speed away from us faster and faster. And yet, more will keep appearing. The farther away a galaxy is […]
If this discovery came in a pre-LIGO era, maybe it would have been a surprise. But in 2019, there’s no mystery at all. Did you hear that astronomers had recently […]
It would be the ultimate method for solving our pollution or hazardous/radioactive waste problems, but we’ll never do it. Here’s why. Imagine our planet as it was for the first 4.55 […]
The quest for the ultimate vacuum just got taken to the next level thanks to a new technique: the quantum squeezer. One of the most understated frontiers in all of […]
Black hole mergers are some of the most energetic events in the Universe. Could the gravitational waves they produce ever harm us? The Universe is not a static, stable place. Out […]
Duke University psychiatrist Harold Koenig describes how.
The post Faith Benefits Health appeared first on ORBITER.
The week-long global protest, which is calling for an end to the age of fossil fuels, is taking place in more than 160 countries today.
Black holes are regions of extreme gravity, but dark matter barely interacts at all. Do they play well together? Black holes are some of the most extreme objects in the […]
There are a lot of unsolved mysteries in the Universe, but dark energy is the most confusing. Here’s why. The majority of the energy in our Universe went completely undiscovered until […]
As soon as you start thinking about energy and gravity, you’ll realize the need to go beyond it. When it comes to a science like physics, theoretical expectations must always be […]
It doesn’t help that Hollywood has cast the ‘coder’ as a socially challenged, type-first-think-later hacker, inevitably white and male.
We cannot give in to fear, but we cannot be reckless when the lives and health of so many are at stake. There is a novel infectious disease that is currently […]
Somehow, the Universe began with just the right mix of cosmic ingredients to make life possible. It sure doesn’t seem likely. When you take stock of what’s in the Universe on […]
What can the beauty of autumn’s colors teach us about mortality?
Here’s what scientists know about how the virus spreads, and how to avoid contracting it.
Maybe, but that probably doesn’t mean what you think it does. Of all the unsolved puzzles in the Universe, perhaps the most confounding is the dark matter problem. If we look […]
In science, breakthroughs don’t always begin with a ‘eureka’ moment. Sometimes, the true story is absolutely unbelievable. When it comes to our Universe’s origin story, many competing ideas once thrived. […]
Small sample size? No underlying theory? Conflicts with all other results? It checks all the boxes. There’s nothing that’s special, on a cosmic scale, about our place in the Universe. Not […]
Within the next billion years, the Magellanic Clouds might merge with our galaxy. But the new stars are already here. Within the Milky Way, there are only a few instances of […]
Over 800 prisoners in Texas relate their experiences.
Over the past 30 years, we’ve revolutionized what we know about the Universe. But we couldn’t have done it without these lessons. On April 24, 1990, the Hubble Space Telescope rocketed […]
Or, quite possibly, is it more complex than either one of those scenarios? If there’s one lesson that humanity should have learned from the 20th century, it’s this: the Universe […]
The Leonid meteor shower peaks today. Its parent comet taught us where meteor showers come from. Every year, as Earth regularly orbits the Sun, meteor showers repeatedly recur. While August’s Perseids […]
And if the data is good enough, we can determine that it’s accelerating directly, too, silencing the last remaining doubters. If you want to understand what the Universe is made […]
We found 10 video games that kids will love (and they’ll secretly be learning, too).
Sure, cosmic inflation has its detractors. But it also has something no alternative possesses: predictions and tests. Perhaps the most compelling part of any remarkable story is its origin: how it […]
