TED-Ed: How far would you have to go to escape gravity? - Rene Laufer
Every star, black hole, human being, smartphone and atom are all constantly pulling on each other due to one force: gravity. So why don’t we feel pulled in billions of different directions? And is there anywhere in the universe where...

Why Do Neutrinos Have Mass? A Small Question with Huge Consequences
Neutrinos are weird. But all the big unsolved problems in physics are somehow connected to one unsolved mystery: Why do neutrinos have mass?

The Mysterious Cosmic Explosion Called “The Cow” | SciShow News
The exploding “cow” around 200 million light-years away is running astronomers for a loop, but if it is what some hypothesize, we are witnessing a first for astronomy! Meanwhile, we got photographic evidence of a planet orbiting a binary...

Black Holes, Neutron Stars, and White Dwarfs (Collab. w/ MinuteEarth)
This video is about the differences between the corpses or final degenerate dense star forms that dead stars take: black holes, neutron stars, and white dwarfs. The main distinguishing features between them are the mass cutoffs...

When Quasars When Quasars Collide STJC
In this video, we discuss the reports about the detection of a pair of supermassive black holes orbiting only one light year apart from each other. Studying the dance of these giants should tell us a ton about how black holes grow.

Danger! Falling Objects
So, what would happen if you dropped a hammer and a feather at the same time, from the same height? Well, the hammer would hit the ground first, right? But why? You might think it's because the hammer is heavier, or has more mass than...

Equivalence Principle
In this video Paul Andersen explains how inertial mass and gravitational mass are equivalent. He shows you too simple methods for calculated individual inertial mass and gravitational mass. Albert Einstein used this principle to build...

Why Do the Planets Orbit in the Same Plane?
While there is a little wiggle room, the planets in our solar system really are orbiting on mostly the same level. Why do they do that?

Linear Momentum
In this video Paul Andersen explains how the linear momentum is equal to the product of the mass of an object and the velocity of the center of mass. He uses video analysis software to calculate the velocity of an object and therefore...

That Galaxy With No Dark Matter It's Probably Not Real - SciShow News
A little over a year ago, we covered a mind-blowing discovery on SciShow Space News. Some researchers even suggested that, if this was confirmed, it would be one of the biggest astronomy findings in years. Except, as it turns out… that...

Mass Spectrometry
In this video Paul Andersen explains how a spectrometer was used to identify the presence of isotopes. This modified Dalton's original atomic theory because atoms of the same element had different masses. The functional parts of a mass...

So, Negative Gravity Is a Thing
In nature, most of our basic forces both attract and repel. In fact, gravity is the only exception. But, according to theorists, sound waves actually have negative gravity.

TED-ED: Why are fish fish-shaped? - Lauren Sallan
In tropical seas, flying fish leap out of the water, gliding for up to 200 meters, before dipping back into the sea. In the Indo-Pacific, a hunting sailfish swims up to 110 kilometers per hour. These feats are made possible by a fish's...

Binary and Multiple Stars
Double stars are stars that appear to be near each other in the sky, but if they’re gravitationally bound together we call them binary stars. Many stars are actually part of binary or multiple systems. If they are close enough together...
