Science of Dark Matter

 - We know that dark matter exists since scientists study dark matter by analyzing its effects on visible objects. Dark matter, according to scientists, could explain the unexplained motions of stars within galaxies. Observations also show the existence of dark energy in the universe. The universe's current expansion rate is faster than in the past, which cannot be explained by gravity.

• The best evidence for dark matter comes from measurements of what is known as the cosmic microwave background. All of the evidence points to dark matter, which accounts for a large portion of the matter in spiral galaxies.

The Greek word for the atom is atomic, which means "indivisible," because the scientists who named it thought it couldn't be split or divided into smaller pieces.

Democritus believed that our world emerged from a vortex of atoms. Many atoms formed a great vortex and collided with one another.

According to Democritus, the mind is composed of a unique class of atoms known as soul atoms, which are spherical and defused throughout the human body.

Yes, since you only separate the ingredients, you would still get the same amount. This example is related to the law of conservation of mass, which states that matter is neither created nor destroyed during a chemical change. The total mass of the reaction products is always equal to the mass of the reactants.

- Electrolysis is the exchange of atoms and ions through the external circuit by removing or adding electrons. It can also help us understand some laws related to atoms.
