All particles belong to two large groups: fermions like protons and electrons make everything we consider "matter", while bosons like photons and gluons transmit the fundamental forces. And that about covers the universe: matter moving...

In this captivating video narrated by astrophysicist Neil deGrasse Tyson, viewers are taken on a journey through the history of the universe, from its explosive beginnings to the evolution of life on Earth. Through a mix of science and...

Computer Color is Broken

What was the 2012 Nobel Prize in physics given for? Capturing a single photon of light!

We can get to Mars in 3 days, . . .sort of, maybe. In this episode of SciShow Space Reid Reimers explains the possibilities of photonic propulsion in use with space travel.

If you could survive a trip to the very first moments of reality as we know it, what color would you see?

Dark matter's most famous trait is its inability to interact with light, the particle version of which we call "photons". But in their attempts to figure out exactly what dark matter is, some scientists have proposed "dark photons".

As much as we like to talk about vibes, actual vibrations underlie pretty much everything about the universe. From the patterns of galaxies created by the Big Bang to the existence of subatomic particles, here's how the universe runs on...

Pin-pricks in the celestial sphere, through which shines the light of heaven? Or gods and heroes looking down from their constellations? Or lights kindled above middle earth by Varda Elbereth and brightened with the dew of the trees of...

Why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale? Many physicists believe that the answer lies in a process known as quantum decoherence.

If a photon leaves the train station shortly after the Big Bang ...

Invisible to the naked eye, our night sky is scattered with the 100s of billions of galaxies the fill the known universe. Like the stars, these galaxies form constellations – hidden patterns that echo the reverberations of matter and...

Causality is meant to move in one direction: forward. But the Quantum Eraser experiment seems to reverse causality. How and why can this happen and what are the implications of this experiment on how we understand Quantum Mechanics and...

Fast Radio Bursts were puzzling physicist for quite some time. They were thought to be the result of large cataclysmic events such as supernovae, but this theory was proven wrong when it was discovered that they could repeat themselves....

The double slit experiment radically changed the way we understand reality. Find out what the ramifications of this experiment were and how we can use it to better comprehend our universe.

Mercury, Venus, and Mars are all super low on water – so where did ours come from and why do we have so much of it? We think our water came from a few unlikely sources: meteorites, space dust, and even the sun.

Quantum computing is cool, but you know what would be extra awesome - a quantum internet. In fact if we want the first we’ll need the latter. And the first step to the quantum internet is quantum cryptography.

If the sun instantly switched off like a light bulb–which can’t happen, by the way–then we wouldn’t know for almost 8 and a half minutes. Light travels at the fastest speed there is, but it still takes almost 500 seconds to get to Earth....

Glass is made of sand, which is a kind of rock. But glass is transparent, and rocks aren’t transparent. What’s up with that? Why is glass clear? And why can I sit on a chair? And why can we touch anything? Today we zoom down to the weird...

If you're lucky enough to find a glowing rock, it likely doesn't mean you're the chosen one. In fact, it could have to do with one of these five phenomena! Learn about the quantum mechanics of glowing rocks in this new SciShow Episode...

The chemistry behind film photography is pretty fascinating. How do film cameras help us turn light into a physical image?

Scientific discovery often dabbles in the extreme, challenging and exceeding what we think of as "possible." And this year's discoveries were no different! We present to you three scientific discoveries made this year that set out to...

Taking photos used to require technical knowledge and time in a lab, but now we have electronic devices in our pockets that do all of the work for us. How do these miracle devices do it? Hosted by: Olivia Gordon

In the 1800s, Wilhelm Kühne created an image of a window from the eyes of a rabbit. Was this technology applicable to humans? Hosted by: Michael Aranda
