If you remember way back to Episode 9, we covered Einstein’s Theory of Special Relativity. Well, that’s only half of the relativity picture. The great scientist made an even more profound impact on physics with his theory of general relativity, replacing Newton with a better model for gravity.

Astronomers continue to find more and more evidence of black holes, but there’s an alternative theory that could explain the observations: gravastars. First proposed in 2001, these objects are one possible solution to Einstein’s field equations, having the same impact on the Universe. But they won’t have an event horizon or singularity. Instead, they’d contain thin shells of matter surrounding an exotic dark energy that pushes back against the star’s gravitational force.
More than a century after he first proposed it, Einstein’s Theory of Relativity is still foundational to our understanding of the Universe.
Could it be that the reason we haven’t met any aliens is because interstellar colonization simply isn’t practical? Not exactly good news for us!
A new study by a team of theoretical astrophysicists shows that stable wormholes could exist, but don’t expect them to be a practical means of space travel.
A team of European researchers observed a pulsar with two orbiting white dwarfs to confirm Einstein’s “most fortunate thought.”
When it deploys in 2025, NASA’s WFIRST mission will rely on the gravitational microlensing technique to locate exoplanets near the center of our galaxy.
For the first time in history, Einstein’s theory of General Relativity was confirmed by observing a star orbiting the supermassive black hole at the center of our galaxy
Dark matter? Who needs it?! Gravity may be something else altogether.
The Big Bang Theory explains how the Universe has evolved over last 13.8 billion years, starting from a singularity to its current size.
