comment Does spinning actually decrease the time experienced by the spinner?
But the decrease in momentum to the Earth is also utterly insignificant. Which of the two effect is more utterly insignificant?

comment What happens when two high-speed objects going opposite directions crash into a black hole?
Hmm. So since kinetic/whatever energy is not separable from the mass energy from the outside of the black hole, thus all that energy would by definition be part of the "mass" of the black hole?

comment Why doesn't everything expand when the universe expands?
I am tired of all these handwavy analogies. I want an actual explanation; I just gave a handwavy analogy that "shows" that everything expands together in my post.

comment Being in a solid state, why is ice slippery?
@dvnrrs Water is an exception: you can put a heavy dumbbell on a huge block of ice and watch as it slowly melts the water underneath it and embeds itself into the ice.

comment Why does a star collapse under its own gravity when the gravity at its centre is zero?
But the fact is that the higher the pressure, the less likely the star collapses. The reason why the balloon collapses when you break it is because when you break it, the pressure goes away. The lack of pressure causes gravity (in the star) or the springiness of the balloon to take over and make the thing collapse.

This is laughably false. Pressure pushes outwards.

comment Why can movies get away with 24 frames per second, but games can't?
This is totally the wrong answer. I'm not asking about flicker on CRTs etc. I'm asking about frame rates on flickerless media such as LCDs and modern projectors. Data update rate is what I'm interested in; on modern screens the flicker is infinity Hz but with a too low data update rate you get a jerky feeling. My question is about why this minimum rate is so much lower for movies than for games.

comment Apparent paradox in special relativity: transmitting a message and setting off after it
What if Mikako waits 2 years before departing? In that case, Mikako would be 2 ly away from Earth when Noboru gets the e-mail. But in that case, if Noboru gets on a spaceship and heads to space, he will still meet Mikako in a very short time.
