Answer:

Matter and antimatter annihilate each other on contact, and researchers believe such collisions destroyed almost all of the antimatter (and a large chunk of the matter) that initially existed in the cosmos.

This created a small surplus of matter, and as the universe cooled, all the antimatter was destroyed, or annihilated, by an equal amount of matter, leaving a tiny surplus of matter. And it is this surplus that makes up everything we see in the universe today.

Answer:

it's all about entropy. Though in microscopic physics, time is treated as directionally neutral--it doesn't matter which direction it's going--the Second Law of Thermodynamics explains why time moves forward only in our visible world.

Explanation:

Gravity is weird because it does not seem to exist in the way we perceive it to be. At the quantum level, empty space consists of a mixture of virtual particles and antiparticles. A virtual particle is not a permanent particle, but a particle that will disappear within an infinitesimal amount of time.

Answer:

No force is more familiar than gravity — it's what keeps our feet on the ground, after all. And Einstein's theory of general relativity gives a mathematical formulation for gravity, describing it as a “warping” of space
