Did you know black holes aren't black? Learn more about space with an episode from a larger series exploring physics. We know more about black holes now than ever before in history, yet we aren't sure we really know anything at all.

What do Russian nesting dolls have to do with physics? They make a great demonstration tool for explaining Dr. Sylvester James Gates, Jr.'s string theory to young scientists. A two-part lesson plan first introduces learners to Dr. Gates'...

Do you see what I see? Individuals view eight images from the Hubble Space Telescope and then determine exactly what is being shown in the images. The pictures range from the rings of Saturn to views of billions of galaxies that take up...

Carve out some time to learn about space-time. Young scientists use a remote learning resource to read up on the relationship between space and time. They consider the idea of relativity, see how objects with a large mass can bend space...

Scientists view every paradox as an opportunity for investigations that lead to discoveries. A short video looks at Stephen Hawking's Black Hole paradox and its implications for general relativity and quantum mechanics. 

Why is the spin of a black hole important? Scholars explore spinning black holes and how they relate to momentum, matter, and mass. They investigate the different parameters that are used to measure black holes by understanding how they...

When did scientists first view a black hole? Believe it or not, it was 2019! It took a century for the theoretical to become a reality, and a lesson from the larger It's Okay to be Smart series discusses the structure of the black hole...

Even light cannot leave the force of a black hole! Learners use a model to explore the gravitational force of a black hole. An elastic bandage and heavy ball serve to create the hole, while marbles become the victims of its strong force.

Have scholars ever wondered what a black hole looks like? See the first image of a massive black hole and learn about what a black hole is, how it forms, and how telescopes took images from around the world. The video then relates the...

What is a black hole? Individuals hear a detailed explanation about what a black hole is, how it forms, and how it effects light and matter. The characteristics of a black hole determine the image it produces in telescopes, and...

The destructive power of black holes is enough to give any astrophysicist nightmares. No wonder the question arises as to whether a black hole can be destroyed. The narrator of a theoretical video explores the possibilities.

Scientists use a telescope larger than Earth to study distant galaxies. Learn how they build and operate such a large telescope as well as some of the cool discoveries with a short video from the SciShow Space series. It also explains...

Time capsules offer a glimpse into the past, and red nugget galaxies are the time capsules of the universe. Using an installment from the SciShow Space series, viewers explore the discovery of new red nugget galaxies. The video also...

With better technology comes better information. An interesting video presentation discusses the evidence that makes scientists believe black holes exist in our galaxy. The narrator explains what a black hole is and how one forms.

Do you ever feel like scientists have more fun naming new discoveries than actually finding them? Discover the fun they had while learning about the extremely scientific concepts of nuclear pasta, gnocchi, spaghetti, waffles,...

Star light, star bright ... just how long can you wish on that star? Well, it depends on its mass. The presentation explains the life cycle of stars based on their sizes. Scholars learn about the life expectancy of a star based on the...

A black hole exists only a couple of thousand light years away from Earth. Should we be scared, or does that mean we are safe? Learn about the perspective of black holes and their relationship with Earth and the larger universe. After...

All stars start with the fusion of hydrogen, but their life cycles vary greatly. The PBS 9-12 Space series introduces star life cycles and explains why they vary so much. Clear animations illustrate the pressure, fusion, collapsing, and...

Once, scientists believed black holes to be rare, but modern technology is proving otherwise. Using data from the Hubble telescope, scientists create computer models of distant galaxies. They discover super massive black holes in the...

The prediction of gravitational waves rocked the scientific world, but it was many years before researchers tested the theory. See how Rainer Weiss applied his knowledge of sound waves to solve this impressive physics problem in an...

Scientists know about a super massive black hole, more than four million times the mass of the sun, at the center of the galaxy. As one part of a video series, astronomers explain this discovery and the many tools used to confirm it....

Astronauts on the ISS continuously fall in a curve thanks to gravity. A video describes the idea of falling along a curved path. Using computer animations, an apple demonstrates the warping of spacetime while the narrator explains the...
