The holy grail of physics is to connect our understanding of the tiny scales of atoms and subatomic particles with that of the vast scales of planets, galaxies, and the entire universe. To connect quantum physics with Einstein’s general...

Reality has cracks in it. Universe-spanning filaments of ancient Big Bang energy, formed from topological defects in the quantum fields, aka cosmic strings. They have subatomic thickness but prodigious mass and they lash through space at...

Our universe started with the big bang. But only for the right definition of “our universe”. And of “started” for that matter. In fact, probably the Big Bang is nothing like what you were taught.

A hundred years ago we discovered...

Now that we have a primer on the aspects of the Big Bang Theory that we know definitely happened, let’s look further into what we don’t yet know, and how the theory could progress in the future. Since there is a discrepancy between...

Throughout history, there has been much speculation about what the fate of the universe would be. Many theorized that the universe would eventually succumb to the pull of gravity, and reverse its expansion in what was being called ‘The...

When pterosaurs first took flight, you could say that it marked the beginning of the end for the winged reptiles. Because, strangely enough, the power of flight -- and the changes that it led to -- may have ultimately led to their downfall.

More people have food allergies than ever before. Peanuts, tree nuts, shellfish, eggs, and even milk… the list of possibly dangerous foods seems to get longer every day. But why do some people’s bodies have deadly reactions food? And why...

Pseudoscience is a set of theories, methods, and assumptions that appear scientific, but aren't. In the worst cases, pseudoscience practitioners encourage this confusion to exploit people. But even when it's well-intentioned,...

We tend to think of evolution as a slow, gradual process playing out over millions of years. But evolutionary biologist Shane Campbell-Staton says nature is now changing at breakneck speed to keep up with the world humanity has built....

Deep in a Sardinian mine, researchers are constructing an experiment that hopes to solve what's known as The Worst Prediction In The History of Physics, and pin down the true identity of dark energy.

In 2023, a whole bunch of orcas started attacking boats off the coast of Spain. Was this the first battle in an all-out interspecies war? Well, probably not. But it's a pretty neat look into how trends come and go in orca pods - like...

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

Hank profiles this year's Nobel laureates in science, whose achievements have helped us understand questions as small as how our cells transport materials, and as big as why matter exists at all.

For the last hundred and fifty years or so, geologists have been trying to wrap their heads around the mystery: in some places, the geologic record just seems to jump by over billion years. And last week, a paper was published that may...

Do you ever think of what could cause the next big extinction? How about a super massive tropical storm that sweeps over continents? Hey, it could happen! Check out this SciShow Dose to see how a hypercane would be possible.

There are still some great mysteries of our universe that physicists can't explain. How is that possible? Join us as we break down the 4 greatest mysteries of physics in this episode of SciShow hosted by Michael Aranda!

Ovens are great for baking, cooking, and.... discovering quantum mechanics? In this fascinating episode of SciShow, Hank takes you through the science of quantum mechanics, and how ovens played a big part in their discovery.

What exactly is hypnosis? Some people think it's just a fun trick for magic shows, but can it actually make you do things against your will? Learn all this and more with Michael Aranda in a new episode of SciShow!

You know how moths like to fly into lamps or crawl all over your tv screen at night? Why do they do this?! The answer is more complicated than you might think...

Hank talks about how warp drives could potentially work.

Researchers have made some unexpected readings of mysterious particles called muons, which may make us reexamine the Standard Model in physics.

The toughest, most dominant canine gets the resources and respect - or at least that's the idea that caught on culturally. Turns out, that's not necessarily how it works.

While you might not think about quantum mechanics being part of your everyday life, it turns out that it might play a role in some of the most familiar things, from the sunlight in the trees to the nose on your face!
