The more you move, the easier it is to keep moving. Maintain the momentum.

The interior of an atom is 99.9999999999996% empty space, which means everything—literally everything and anything of physical substance in the universe—is, somehow, mostly nothing.

It would take 375,000 Lego bricks stacked one on top of another to destroy the bottom brick. The tower would be 12,000 feet tall, applying a force of 4,200N (equivalent to 950lbs). Everything has a breaking point.

Eventually the only objects remaining in the universe will be supermassive blackholes. Until then let's have some fun.

Great to see astronomers detect x-rays from behind a supermassive black hole, proving Einstein and general relativity right again. Physics works. The power of these supermassive black holes to warp spacetime is awe-inspiring. PS: We're lucky to be 100 million light-years away.

Quantum mechanics is a "lazy evaluation" physics engine that renders reality only when observed. The engineering question for the simulation is: How hard is it to efficiently render reality that fools humans by still appearing to be globally consistent with the laws of physics.
