Nobel is a world-renowned inventor. What did Nobel invent? Counting carefully, Nobel has a total of 355 patents in his lifetime, and has opened more than 100 company factories in 20 countries. What Nobel invented, in fact, is mainly about dynamite. After

We know that there are black holes, white holes and wormholes in the universe. So what are gray holes? In the past, Hawking was famous all over the world for proposing the theory of black holes, but later Hawking said that there are no real black holes in

We all know that there is a sonic boom, so is there a light boom? After a search, I found that the light boom does exist, and the principle is similar to the sonic boom. However, the phenomenon of light explosion is even more powerful, and even in the pro

Famous physicist Stephen Hawking, Hawking predicted that the earth will be destroyed within 200 years, Hawking said that if human beings want to continue forever, they have to immigrate to other planets, the earth will perish sooner or later, Hawking pred

Coronal mass ejection is a huge gas ejected by the sun. Because it is in a white gas state, its shape is called a bubble-like shape. The coronal object contains a strong magnetic field, and the magnetic field lines are attached to the magnetic field. arou

British research finds less than 1% of the 10 million tonnes of ocean plastic floating accumulation. Scientists at the University of Manchester in the United Kingdom found that among the 10 million tons of plastic floating in the global ocean every year,

For the first time, researchers have observed the precession effect of a star's orbit around a giant black hole, proving yet again that Einstein's theory of relativity is correct. An artist's impression of the precession of a star's orbit around the supe

"It bewitches our ears, just as it cunningly attacks our cells." Scientists at the Massachusetts Institute of Technology (MIT) wrote music according to the protein structure of the new coronavirus (New Coronary Pneumonia), author Buhler (Markus) Buehler)

Scientists did not understand before that how plants can ensure that the metabolic system does not perform too much photosynthesis and consume too much energy on days with sufficient light? Recent research has found a switch mechanism, which has breakthr

We all know that the gravity of a black hole swallows everything, including light. But that's for objects right near the black hole, for the accretion disk right next to the black hole, where light can escape. Scientists have found that this is actually

A study by the U.S. Department of Energy's SLAC National Accelerator Laboratory and Stanford University has found that putting a hollow laser beam around the electron group can produce stronger X-rays. Scientists compress and accelerate groups of electro

Most scholars believe that the movement of the earth's plates first began 2.8 billion years ago. A new study has found evidence that a plate was active 3.2 billion years ago, 400 million years earlier than scientists previously knew. "This is one piece o

The atmosphere of Venus is rich in sulfuric acid, and thick clouds surround Venus. Although Venus is not the closest to the sun, its surface temperature is the highest. Even more oddly, Venus spins very slowly, but its atmosphere spins pretty fast. One d

Australian and French researchers have found that "macrophages", the cells that form the immune system's first line of defense, become "paralyzed" after a severe infection. Macrophages in a mouse are pictured extending their pseudopodia, engulfing two pa

Salmon (commonly known as salmon) is a well-known anadromous fish. When they reach the breeding season, they can return to the upper reaches of the river to lay eggs and reproduce the next generation, as if they have a compass inside them to guide them.

University of Alberta, Canada Alberta biologists have developed a tool for sequencing circular DNA that will provide more accurate data for the study of viruses, crops and cancer. Schematic diagram of circular DNA sequencing. Devang Mehta/University of A

A new study analyzes the shock waves of multiple earthquakes at the same location and finds that the refraction of the shock waves has changed. It is believed that this is the most powerful proof that the earth's core has rotated relative to the crust, a

A survey of nearly 400 sun-like stars shows that our sun is a relatively calm celestial body, and the probability of a solar storm erupting is much smaller than other stars. Is this a coincidence? Or is there an unknown force keeping the sun stable? Scie

How does the interaction of particles in the universe make the universe evolve into the structure that people see now? By pooling data from vast numbers of galaxies, a team of researchers worked backwards to develop a theory that could explain the struct

New research has found that the ocean disperses microplastic particles into the air and blows them to the shore. The sea breeze that people go to the beach to breathe contains microplastic particles. Fragments of domestic waste such as plastic bottles an
