Anonymous users2024-02-06Xinhua***: According to the Associated Press, the Large Hadron Collider (LHC) was built to help scientists gain a deeper understanding of the nature of the universe and the origin of matter. Q:
What is LHC? A: It is the most powerful particle accelerator in the world, buried in a 27-kilometer-long underground tunnel surrounded by large detectors.
Q: What is a "hadron"? A:
Refers to particles found inside the nucleus——— such as protons or neutrons. Q: Who built the collider and how much did it cost?
A: Scientists from the European Organization for Nuclear Research (CERN) came up with the idea for this project in 1984. The organization's 20 member countries, as well as observer countries such as the United States and Japan, have contributed about $10 billion to the project.
Q: How does the collider work? A:
The collider emits protons around the tunnel at nearly the speed of light. Ultra-cold magnets guide protons in opposite directions and collide. Q:
What does a detector do? A: When protons collide, the probe will look for dimensions other than what we know to be the three dimensions of space and the one dimension of time.
They will also look for "dark matter" (scientists believe that most of the universe is made up of dark matter), antimatter (mirror matter of known matter), and the hitherto unseen Higgs boson (which explains how various other particles have mass). The existence of all these substances before was theoretical and never proven. Q:
What about the "cosmic big" part of this experiment? A: A probe will observe the collision of lead ions, simulating what happens after the cosmic mega-instant.
Scientists hope to understand how matter is formed. Q: What else do scientists want to know?
A: If the collider proves the existence of new particles, it may test the well-known physics hypothesis "string theory". The theory attempts to describe quantum mechanics and gravity with a unified formula.

Anonymous users2024-02-05The Large Hadron Collider (LHC) is currently the world's largest particle accelerator under construction, with a tunnel length of 27 km. After the completion of the collider, two beams of protons or heavy ion streams like lead can run along the annular tunnel in opposite directions, and each time the particles run will gain more energy, and finally accelerate the protons to a fraction of the speed of light, so that the two beams collide head-on with an energy of up to 14 trillion EV, which is used to simulate the cosmic situation after the occurrence of the "big **", and obtain a huge energy equivalent to the explosion of a billion seconds after the "big **" of the universe to smash elementary particles.
It's not started yet.
However, the LHC (Large Hadron Collider), a $6 billion project involving 33 countries (including China), which began in the 80s of the last century, really has nothing to worry about. >>>More
Today, high-energy accelerators are huge, such as Fermillab's 1,000 billion electron volt proton synchrotron, which has a circular orbit of more than 6,000 meters. If the energy is to continue to increase, the footprint of the accelerator will inevitably increase significantly. For example, an accelerator with an energy of 100 billion electron volts will be made as big as the Earth. >>>More

There is a lot of harm, almost every Western medicine has ***, hormones are especially obvious, it will obviously gain weight, and it will have an impact on all aspects of the body. In particular, it will affect the growth and development of children, but hormone drugs are very useful for controlling the disease as soon as possible.
