John Dalton, an English scientist, proposed that atoms were the smallest indivisible particles in the universe in the early 19th century. His atomic theory laid the foundation for modern chemistry.
The second smallest thing in the world is thought to be a quark, which is a subatomic particle that is a building block of protons and neutrons. Quarks are fundamental particles that are not thought to have any substructure.
The particle thought to carry the electromagnetic force is called the photon.
"WIMP" stands for Weakly Interacting Massive Particle. It is a hypothetical type of dark matter particle that is thought to make up a large portion of the universe's mass. WIMPs are predicted by some theories in particle physics, such as supersymmetry.
graviton.
In the theory of general relativity, the gravity particle, also known as the graviton, is a hypothetical particle that is thought to mediate the force of gravity. It is believed to be responsible for transmitting gravitational interactions between objects in the universe. However, the existence of the graviton has not been confirmed experimentally, and its role in general relativity is still a topic of ongoing research and debate.
Democritus, the ancient Greek philosopher, was the first scientist to propose the concept of atoms as the smallest particle in the universe. He believed that all matter was made up of indivisible and indestructible particles called atoms.

When you consider the composition of living and non living things, both can be broken down into what comprises them. If one considers non-living matter, then "particle" may be used to describe the smallest unit. As knowledge advances, a "particle" by definition has evolved i.e., quarks being the smallest "particle" of an atom whereas for years it was thought that the atom was the smallest unit of matter. Conversely, the cell is considered the smallest unit of organic (living) matter The only major difference between them is that a cell is the smallest particle of a living object and a molecule (made up of atoms) is the smallest unit of a nonliving object.
Personally, i love that question. Well, since man kind does not quite know the size of the universe, no answer is quite accurate. however, think of this. the universe might be so unimaginably large that a single particle and Earth, as far as science is concerned might not even be thought of as different sizes at all. Compared to the immense universe, all masses we know of are so insignificant that they are not even thought of.

he thought that the earth was the center of the universe
The Higgs particle, also known as the "God particle", is a missing piece of the puzzle in helping us to understand how the universe works. Scientists believe that milliseconds after the Big Bang, an invisible field of energy was formed. As particles from the Big Bang passed through this field, they acquired mass and shape, and eventually formed into atoms, which now make up everything in the universe. Without this proposed field, particles would simply whizz around space as light would. In July of 2012, an unknown boson particle was discovered. Its properties are still being studied, but many physicists are confident that the God particle has been found. If the Higgs particle has indeed been discovered, incredible advancements could be made in the field of medicine, computing and electronics, and in the quest of learning how the universe came to be.
graviton.
The Greek astronomer Claudius Ptolemy believed that Earth was at the center of the universe in his geocentric model, which was widely accepted in the ancient world. This view held sway until the heliocentric model proposed by Copernicus in the 16th century challenged it.
infinitive: think past: thought past participle: thought
The idea that thought created the universe is purely speculative and not supported by scientific evidence. The current understanding is that the universe was formed through natural processes such as the Big Bang.
