Examine life’s biggest questions, from ethics to existence, with curiosity and critical thinking.
There are plenty of questions we don’t know the answer to. With quantum gravity, they might be solved! This article is written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized […]
For the first time, I genuinely enjoyed the new series. There’s been one question that’s bothered me in every episode since Star Trek: Discovery began: why would anyone want to be […]
Do we need quantum gravity? We sure do… and here’s how we’re trying to get there! Our current best theories describing the Universe, general relativity for gravity, quantum field theory for […]
Either possibility offers a tremendous existence, but philosophically, there’s so much more to think about. “If the doors of perception were cleansed every thing would appear to man as it is, […]
Finding a warm-hot intergalactic plasma is amazing! But we still need dark matter just as much as ever. “There are stars leaving the Milky Way, and immense gas clouds falling […]
If your favorite theory made the list, you might want to consider a new favorite to bet on. “Some people believe holding on and hanging in there are signs of great […]
It’s a fascinating idea, but how does it fare as a scientific theory? “Something is happening here and this is going to have an impact.” –Robert Dijkgraaf, on Verlinde’s work The […]
Want to be hotter? Add more mass. Want to go even hotter than that? Lose almost all of it. “A candidate is not going to suddenly change once they get into […]
When matter falls in, black holes grow. But Hawking radiation says that black holes decay. Who wins? “Maybe that is our mistake: maybe there are no particle positions and velocities, but […]
More than 90% of the eclipses to ever happen on Earth have already occurred. Don’t miss the next one! “We live in a moment of history where change is so speeded […]
It’s a great show in total darkness. Here’s how to not ruin it for yourself. “Yes, I am well aware that nature — or what we call nature: that totality of objects […]
It isn’t about saving us from aliens at all. “To be on my very first spacewalk, to be outside, and to have contamination in my suit to the point that I […]
The speed of light is a universal constant, but that doesn’t necessarily mean that light always travels at that speed, does it? “There was a young lady named Bright,Whose speed was […]
With quantum teleportation now occurring from Earth to satellites, how long is it before we can teleport a human being? “There would be no Star Trek unless there were transporter malfunctions.” –LeVar […]
Falling into a black hole is forever… but could a tether to the outside pull you back out? “Nobody ever did, or ever will, escape the consequences of his choices.” –Alfred A. […]
Why does the Universe have the properties it has? There may be no natural reason at all. “When you listen to a lecture, you should not have any idea of yourself. […]
Someday, the Sun will heat up enough to boil our planet’s oceans. Could moving the entire Earth away save us? “I would argue that in any habitable zone that doesn’t boil […]
How to stay safe and prepare yourself for the show of a lifetime! “Nations, like stars, are entitled to eclipse. All is well, provided the light returns and the eclipse […]
Brown dwarfs are the ultimate failed stars, but they might not remain as failed forever. “[Brown dwarfs] appear to live a more exciting life than we presumed. They are too big […]
A new podcast, to cover an incredible story of why we can exist at all. “Already in my original paper I stressed the circumstance that I was unable to give a […]
