Einstein’s Biggest Blunder

In 1917, Albert Einstein inserted a term called the cosmological constant into his theory of general relativity to force the equations to predict a stationary universe in keeping with physicists' thinking at the time. 

Today on Far Future Horizons we present two video features that explore Einstein's "biggest blunder". 

“Einstein’s Greatest Blunder” was REALLY a blunder!

When it became clear that the universe wasn't actually static, but was expanding instead, Einstein abandoned the cosmological constant, calling it the '"biggest blunder" of his life. 

Was it the earliest prediction of Dark Energy?

At the dawn of the twenty-first century, a new theory is being born. It threatens to demolish the foundations of 20th century physics. Its authors are two of the world’s leading cosmologists. If they’re right, Einstein was wrong.

If there is one thing “every schoolgirl knows” about Einstein and his theory of relativity, it’s that the speed of light is constant. Yet today a small group of brilliant physicists and astronomers have risked their scientific reputations to question the validity of this idea. Could the speed of light of change?
