Tachyons

In a new paper that has yet to be peer-reviewed, the physicists propose that our universe is dominated by tachyons — a hypothetical kind of particle that always moves faster than light. Tachyons almost certainly don't exist; going faster than light violates everything we know about the causal flow of time from past to future.

What are Tachyons?

1. Tachyons are theoretical particles that physicists believe could travel faster than the speed of light.
2. Unlike familiar particles like protons, electrons, and neutrons (called "bradyons"), tachyons have never been directly observed.
3. Special relativity suggests that normal matter can't reach the speed of light, but tachyons might be different. They are thought to have "imaginary mass," which could allow them to break the light-speed barrier.
4. If tachyons exist, they would behave strangely: they'd slow down when they gain energy and speed up when they lose energy.
5. Scientists use specialized detectors called Cerenkov detectors to search for tachyons. These detectors look for signs (like a light-based equivalent of a sonic boom) that would occur if a particle traveled faster than light within a specific material.

FAQs:

Q1: What are protons?

1. Protons are tiny particles found inside the nucleus (center) of every atom.
2. They have a positive electrical charge.
3. Protons are usually found together with neutrons (which have no charge) inside an atom's nucleus.
4. The simplest element, hydrogen, is an exception – its nucleus only contains a single proton.
