When you cross over the edge of a black hole, space and time interchange their roles. You are drawn toward the black hole's center with the same inevitability as you are drawn to the next moment in time.

A common misunderstanding: In quantum teleportation, matter is NOT teleported. Instead, quantum information describing matter is teleported. Which raises the question: Are you the sum of your information?

Tomorrow morning: Event Horizon Telescope reveals the first direct image of the edge of a black hole. Most exciting possibility: The image does not fully agree with the prediction from Einstein's general relativity, perhaps forcing us to modify Einstein's equations.

Grasp a glass and you don't actually touch it. Electrons in your hand push against those in the glass creating a tiny but unbridgeable gap. Sit in a chair and you actually hover slightly above its surface. You've never had direct physical contact with anything.

"I much prefer the sharpest criticism of a single intelligent man to the thoughtless approval of the masses."--Johannes Kepler, born OTD 1571.

We thought all galaxies contain a substantial amount of dark matter. The new surprise: some don't. https://t.co/zTPas6ZSsr

Here's what still puzzles many of us regarding quantum mechanics: How does the theory bridge the fuzzy, probabilistic, mathematical description with the single, definite reality of common experience?

"We don't know a millionth of one percent about anything." --Thomas Edison, died OTD 1931.

It's Official: Gravitational waves from colliding neutron stars detected--first ever events both heard with gravity and seen with light.

"Men are born ignorant, not stupid; they are made stupid by education." -- Bertrand Russell, born on this date, 1872.
