Scientists are scouring the universe for evidence of extraterrestrial life, but have you ever wondered how life began on Earth? Let physicist David Kaplan explain in the latest installment of Quanta’s “In Theory” video series. Hint: it’s all because of increasing entropy.
Here’s a question worthy of the ball boy at Wimbledon: if you have 128 tennis balls packed into a container, how many different ways can you arrange them? Answer: 10250 — more than the entire number of subatomic particles in the universe.
Now you can watch as well as listen as world-renowned physicist Stephen Hawking expounds upon his latest ideas about the knotty black hole information paradox, playfully illustrated by chalkboard artist Andrew Park.
If you want to hear something very quiet, you need to reduce the ambient volume of your surroundings. For quantum physicists, though, that meant creating the world’s quietest gas.
Black holes have a justifiably terrifying reputation. If you drop your keys in there, forget them, because they are gone. But are matters really so bad? Can a black hole "remember" what it's eaten? In this week's "Ask a Physicist" we'll find out.
A provocative new paper is proposing that complex intelligent behavior may emerge from a fundamentally simple physical process. The theory offers novel prescriptions for how to build an AI — but it also explains how a world-dominating superintelligence might come about. We spoke to the lead author to learn more.
You would think that shaking up a box with a couple of chains inside would end in sadness and a bunch of knotted chains, but as you can see in this video, it doesn't always work out like that. These two chains - both made of plain metal beads - coil and uncoil around each other until they are completely separated.…
The longer you use a computer, the hotter it will get. That seems like just an everyday fact of life, but it might actually be its own law of physics. And, like all phyiscal laws, quantum mechanics apparently violates it.
There's a theory that involves every cool buzzword in physics. This theory links the dark energy in the universe with the way photocopies degrade over time. Find out how a loss of information may drive energy creation.
In this week's Ask a Physicist, we're going to go old school and do some thermodynamics. I'll explore why disorder is such a big deal and whether it might explain the mysteries of how time works.
In Hyderabad this week, Anthony James Leggett delivered some unwelcome news: The earth is warming. Good science teachers are increasingly rare. Oh, and we can't manipulate the flow of time.
According to researchers at Australian National University, the end of the universe will happen earlier than anyone previously thought. The mother of all deadlines is coming up!
Supermassive blackholes, heat death, and entropy could be wonderful dinner conversation as you toast to the end of the universe. Not sure when it'll happen, but based on recent universal entropy re-calculations, it'll be sooner than we expected.
Are supermassive black holes bringing about the end of existence? It's a surprising claim, but one being made after scientists have discovered that the black holes are the largest contributors of entropy in the known universe.
