Question

1)why is gravity so weird???
2)why does time seem to flow only in one direction???
3)where did all the antimatter go??
4)what happened in the gray zone between solid and liquid????​

Answer 1

1. 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.
2. 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
3. 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. explains why time moves forward only in our visible world.
4. Hence from liquid to solid or solid to liquid the transition has to cross the grey zone. This grey zone transition is is very crucial which includes the inter molecular forces acting on the molecules and each atoms which makes the change in state from hot to cold and cold to hot.

Answer 2

Answer:

1). 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 forgravity, describing it as a “warping” of space.

2). 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.

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

4). Solids and liquids are well understood. A grain ofsand is as solid as a rock, but a million grains can flow through a funnel almost like water. ... And highway traffic can behave in a similar way, flowing freely until it becomes blocked at some bottleneck.
