The most classic "miracle of strength" in the history of science
You will be surprised to find that you are so sensitive to changes of a few degrees when arguing with people about whether the air conditioner is set at 26 degrees or 27 degrees, whether the drink you bought from the kiosk is cold enough after exercise, and whether your palms are "fried" when enjoying the view of Lizuna Port in a hand game.

Astronomers: Senkaku IV was pierced by a mysterious force before it became dark
Every shining star in the universe will be extinguished one day, and its "lifespan" is closely related to its mass. For example, Proximal is about 12.2% of the Sun's mass, and its "lifetime" can be as high as trillions of years, while the Sun's "lifetime" is only about 10 billion years, and those stars are much larger than the Sun, its "lifetime" is even shorter.

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?
