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

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...

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....

HAS SPACE ALWAYS BEEN BLACK? As long as we've been around, YES. But the universe gets much more exciting, AND much BRIGHTER, as we start winding our clocks back to the early days of the universe. Near the beginning of the universe, when...

Models of the universe’s early days have only been possible with dark matter as a variable, but we still don’t have proof that dark matter exists. But recently, scientists may have found a way to replicate the results without the...

Almost all matter in the universe should have been annihilated shortly after the Big Bang, but looking around, we see galaxies, stars, planets, and, you know... us. So obviously that didn't happen, and the why of it may have something to...

The name “The Big Bang” makes it sound like there was a big explosion in one particular spot, but if that’s the case, where did it happen?

If we look as far out as possible, we would see a uniform glow of low level radiation in all directions. This is called the cosmic microwave background, or CMB. It is the oldest light in the universe. And it...

Summary:

The information that we know about the universe comes almost exclusively from the analysis of electromagnetic radiation. But there is only so much this light can reveal because there is an inherent...

Dark Flow. We investigate why hundreds of galaxy clusters are rapidly drifting towards a specific point just outside the known universe.

From ancient civilizations to modern breakthroughs, learn about the nine most important cosmic discoveries that changed the way we look at our Sun, Moon and beyond. Learn how Copernicus challenged the status quo, Kepler unveiled the...

The fastest particles ever detected in the universe are still a mystery to science. Cosmic rays are particles from space. The most energetic and fastest particles we’ve ever detected come from a mystery place. In this video inspired by...

When light passes through the universe and is redshifted by the expansion of space itself, how is energy conserved? The stretched light has a longer wavelength and therefore a lower energy. Is energy conserved? If so, where does it go?

The universe is microwaving itself. A mystery signal discovered in the 1960s led to a Nobel prize. In this video, Dianna explores one of the most mysterious discoveries in physics - a constant microwave signal that seemed to be coming...

The ill-fated "discovery" of primordial gravitational waves in the cosmic microwave background, explained in a cosmology rendition of Disney's "The Circle of Life" from the movie "The Lion King"
