Einstein’s most famous equation wasn’t first introduced by Einstein, and Einstein didn’t derive it.
A Light Change
Was the speed of light much faster in the early universe?
Echoes From The Abyss
Observations of gravitational waves might allow us to test the quantum properties of black holes.
The Stars Uncounted
The relativistic effect of gravitational lensing allows astronomers to see the faintest galaxies.
Are You A Black Hole?
You aren’t a black hole, and that means a particle moving at nearly the speed of light isn’t one either.
Black Holes With A Twist
If you were to spin a ball, for example, the texture of the ball’s surface would make it easy to see the ball is rotating. But what if the ball were perfectly smooth?
The Man Behind The Curtain
Black Holes are where God divided by zero, so the saying goes.
Why Does Gravity Wave, And Why Does It Matter?
What are gravitational waves, and why is their detection such a big deal?
Testing Relativity With Fast Radio Bursts
Fast radio bursts are strange bursts of energy originating from outside our galaxy. Their short duration means they could be used to test the limits of general relativity.
