Why does the sea rise and fall at high tide?
People who live by the sea know that seawater always goes in and out, and the sea surface has a rise and fall. At low tide, the seawater will gradually recede, the sea gradually backs down to reveal a large beach; at high tide, the seawater from the depths of the ocean will continue to surge up the coast, the waves roll, and the water level rises.

How to save yourself from the "man-eating" offshore currents?
On the afternoon of July 31, two young tourists were swept away by a wave and disappeared into the sea in Qingdao, Shandong Province. The video released by citizens shows two young guys watching the sea and taking photos on the dike outside the guardrail, when a wave kept coming over, then a huge wave knocked them both down and swept them into the sea.

The Earth is carrying mankind through the universe, where is the destination?
There are many counter-intuitive phenomena in the universe, for example, according to our human intuition, the earth under our feet should be stationary, but in fact, the earth is carrying human beings flying through the universe, only because all the objects on earth are moving together with the earth, we can't feel it.
Dinosaurs are not all extinct and still on earth
I believe that everyone is no stranger to dinosaurs. After all, they were once the overlords of the earth. Usually, we all think that dinosaurs are ancient creatures that have long been extinct, and there are no dinosaurs alive on modern earth.
Why have no advanced civilizations visited Earth?
The Earth was born about 4.55 billion years ago, and over a long period, life on Earth has gone through a process from nothing to something, from simple to complex, and eventually evolved into humans with higher intelligence.
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?
Uranium keeps decaying, so why is there still uranium on Earth after 4.55 billion years?
Why does uranium decay? Uranium keeps decaying, so why is there still uranium on Earth after 4.55 billion years? Uranium is an important raw material for the use of nuclear energy, but it is also a radioactive element that decays. Why does uranium decay? It starts with the microscopic structure of the atom.
Where do all the planets swallowed by black holes end up?
The gravitational force of black holes is so strong that they can swallow any matter known in the universe, even if they are huge planets, as long as they enter the "sphere of influence" of black holes, they also cannot escape the fate of being swallowed. Here we will talk about this topic.
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.
