Dear student 
1. matter is made up of what atoms and molecules are made of, meaning anything made of positively charged protons, neutral neutrons, and negatively charged electrons.
2. 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.
3. Originally Answered: Why does time appear to move in only one direction? Time moves forward because a property of the universe called "entropy," roughly defined as the level of disorder, only increases, and so there is no way to reverse a rise in entropy after it has occurred.
4. But we exist, and therefore something must have happened to allow matter to survive and antimatter to all but disappear. Scientists suspect that a tiny portion of matter—about one particle per billion—survived from the early universe to create all the planets, stars and galaxies we see today.
5. In the grey zone between solid and liquid. Explanation: ... Hence from liquid to solid or solid to liquid the transition has to cross the grey zone
6. no we cant.....
7.If the universe did begin with a rapid expansion, per the Big Bang theory, then life as we know it sprung from nonliving matter. ... It proposes that in Earth's prebiotic history, simple organic matter was exposed to energy in the form of volcanoes and electrical storms
