No.You don't actually see particles. What happens is the particles leave tracks in detectors and that data is changed into something that can be illustrated with a computer.TeCNoYoTTa said:Sorry if this question is stupid, but how particles are simulated (seen) in the LHC like this

does not that contradict with uncertainty principle ?
Can we actually see particles ?

Seeing is a biologgical process of photons entering the eye and being processed by the brain. In reallity we only really "see" light. When it is said that we "see" something what we mean is that what we are observing is interacting with light and its the light coming from the object that we see.
Consider a tunneling electron microscope. Current is established through the tip of a needle, the strength of the current being a function of the distance between needle and the sea of electrons which comprise the outer conduction electrons in matter. That current is recorded and then the data displayed on a computer screen the like. What is illustrated by the computer is a representation of the surface of matter. In this way we can "see" the atoms that comprise the surface of the material we are analyzing. But what we're really looking at is an averaged out representation of what is being analyzed.
Make sense?
TeCNoYoTTa said:Thanks, It makes sense now.
but what if there are particles out there that does not interact with electric current, is not that possible ? won't these particles be left unrecognized although they are actually there ?
The LHC, or Large Hadron Collider, is a particle accelerator located at the European Organization for Nuclear Research (CERN) in Switzerland. It uses powerful magnets to accelerate particles to nearly the speed of light and then smashes them together, simulating the conditions of the early universe. This allows scientists to study the behavior of particles and search for new ones.
Simulating particles at the LHC allows scientists to test and validate theories about the fundamental nature of matter and the universe. It also helps us understand how particles interact and how they came to form the structures we see in the universe today.
The LHC can simulate a wide range of particles, including protons, neutrons, electrons, and various types of subatomic particles such as quarks and gluons. These particles are the building blocks of matter and by studying their behavior, we can gain a deeper understanding of the universe.
When particles collide at the LHC, they create a shower of other particles that can be detected by specialized instruments. These instruments, such as the Large Hadron Collider beauty (LHCb) detector, can track the paths of particles and measure their properties, such as mass and energy. This data is then analyzed by scientists to make observations and draw conclusions about the particles being simulated.
The LHC has helped confirm the existence of the Higgs boson, a subatomic particle responsible for giving mass to other particles. It has also provided evidence for the existence of dark matter, a mysterious substance that makes up a significant portion of the universe. Additionally, the LHC has allowed scientists to study the properties of particles at extremely high energies, providing insights into the behavior of matter in extreme conditions.
