What would happen to the Earth if the sun suddenly disappeared?
What would happen to the Earth if the sun suddenly disappeared? The answer, of course, is that the Earth will undergo a dramatic change, but in the moment of the disappearance of the sun, the Earth will not immediately change, because the speed of propagation of solar light and gravity is the speed of light, about 300,000 kilometers per second, and the average distance between the Earth and the sun is about 150 million kilometers, so in about 500 seconds, the Earth's dramatic change will begin, and from then on to kick off a difficult human survival.

Put the compressed spring into strong acid
The spring itself is elastic, after being compressed, the spring will have the tendency to return to its initial state, and therefore has elastic potential energy, which we can see as the energy stored in the spring as a whole system, so the question arises: if the compressed spring is put into a strong acid, then after the spring dissolves, where does the energy of the spring go?

What is "vacuum decay"? Can "vacuum decay" really destroy the entire universe at the speed of light?
"Vacuum decay" is a hypothesis hypothesized by physicists based on quantum field theory, which is interpreted as follows: if there is a "vacuum decay" in a certain region of the universe, then The "vacuum decay" will spread from that region to all directions at the speed of light and eventually destroy the entire universe. What is this all about? Here we will talk about this topic.
