Let's look further into what we don't yet know about the Big Bang, and how the theory could progress in the future. Since there is a discrepancy between general relativity and quantum mechanics, we continue to search for a grand unifying...

if you took a notebook, a plastic bottle, a toaster, and a glass container and burned them in a fire hot enough, around 10^31 degrees Celsius, all the particles and forces, would become one entity. This is what...

What is the Electroweak force? Electroweak theory explained: At the moment of the Big Bang, all 4 fundamental forces were probably the same. But as temperatures and energies lowered, the forces separated into...

Summary:

In this video I explain what supersymmetry is, why physicists think it should exist, why we haven't discovered it, and why it is necess

There's a theoretical idea that could get...

We've gone through some of the main advancements in modern physics, which brings us to the here and now! What are physicists currently working on? One huge area of interest is developing a quantum field theory for the gravitational...
