The Times When Einstein Blundered
1. Mistake in proving E = mc² equation. Actually, in all 7 proofs he provided.
Einstein produced 7 proofs for the famous E = mc² equation, in 1905, 1906, two in 1907, unpublished paper in 1912, and two more papers much later, in 1935 and 1946
Incredibly as it sounds, all these proofs had a mistake, in one way or the other.
From making unjustified assumptions or restrictive approximations to making logical mistakes, Einstein actually never succeeded in proving the famous equation without an error
2. He didn’t believe gravitational waves exist, even though he proposed them first
Soon after developing the theory of General Relativity, Einstein began to wonder if there might be waves associated with the field of gravity in analogy to electromagnetic waves
He moved on to other problems, but when he returned to the question of gravitational waves two decades later, he concluded that gravitational waves couldn’t exist because they would create singularities in space.
The gravitational waves were observed in 2016, exactly 100 years after they were first predicted by Einstein.
3.He thought light bending by gravitational lenses will never be observed
In General Relativity, the light follows the curvature of spacetime, and when it passes around a massive object, it bends. This phenomenon is known today as gravitational lensing.
For gravitational lensing to be observed, the source, the lens, and the observer have to be in almost perfect alignment. Since the initial discussion was centered only around the stars, it was unanimously believed that the necessary alignment would be highly improbable, and thus the effect would be nearly impossible to observe.
Only a year later, astronomer Fritz Zwicky was the first who considered gravitational lensing from galaxies.

There is a ton of evidence for Israel's exodus from Egypt, but it is sadly missed by many scholars because most are convinced the Exodus must have taken place in another time period. In this documentary, we explore the mountain of evidence for the Exodus and argue the Bible is recording a historical event.
