The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it valid? No matter who you are, where you are, or how quickly you’re moving, […]
And one of our planets has the orbiting moons to prove it. Despite the dangers posed to planet Earth by a comet or asteroid strike, our Solar System is actually an […]
An entire Universe of possibilities await stars like our own, even after they run out of fuel. One of the most profound rules in all the Universe is that nothing lasts […]
Imagine how different our understanding of the Universe would be if we saw nothing beyond the Milky Way. Our corner of the Universe was gifted with a plethora of bright, nearby […]
What’s more massive than the heaviest known neutron star but lighter than the lightest known black hole? LIGO may be about to solve that mystery. Whenever a star is born in […]
If the multiverse is real, where does all the energy for it come from? One of the biggest scientific puzzles, even given our knowledge of the Big Bang, is to understand […]
In order to reap the greatest rewards, we have to think big and invest big. One of these four missions will deliver like never before. When it comes to exploring the […]
50 years ago, Apollo 9 launched. Without it, we never would’ve landed on the Moon. The Apollo program is most famous for its greatest achievement: taking humanity to the Moon. It […]
The dream of multi-messenger astronomy is to seen an event with gravitational waves, neutrinos, and light all together. The newest candidate just might get us there. When it comes to cataclysmic […]
Have we always had quantum fields in the Universe? Or did they emerge at some finite time? No matter how we look at the Universe — at low temperatures or ultra-high energies, from […]
Galactic mergers should push gas and dust into the centers of galaxies. So why are these two so quiet? Scientists have studied the closest, largest, brightest galaxies to Earth for centuries. […]
Even in the most exotic scenario imaginable, they still can’t remain stable in the Earth’s interior. It’s well known among scientists that if you submit even the most nonsensical paper […]
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 […]
In all the Universe, there’s only one Earth. But can we find the other worlds that are like ours? Even though the ingredients for life have been confirmed to be practically […]
They’re not just a theoretical prediction of quantum gravity. They should be detectable, too. The Universe, if you look at it closely and carefully enough, is fundamentally quantum in nature. […]
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 […]
There are three answers depending on what you consider the “edge,” but only two of them are known. If you were to go as far out into space as you can […]
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 […]
