Question

Simplest particle in universe?​

Answer 1

Answer:

Quarks

Quarks are among the smallest particles in the universe, and they carry only fractional electric charges. Scientists have a good idea of how quarks make up hadrons, but the properties of individual quarks have been difficult to tease out because they can't be observed outside of their respective hadrons.Actually, quarks as well as electrons. When physicists first collided electrons with protons, they observed that electrons bounced off three small hard nuclei inside the proton. The cores were then called quarks. Quarks are the smallest particles we have come across in our scientific endeavor.

Answer 2

Answer:

Scientists have long wanted to find the most basic building blocks of the universe. They asked, “what are the fundamental particles of matter that cannot be subdivided into smaller, simpler particles,” and “what holds these particles together?” Scientists thought they had finally found them when John discovered the atom in 1803 (see the timeline in Table below). The word atom means “indivisible,”
