There is a theroy that universes "reporduce" through black holes, and that part of the criteria that requires this also by coinsidence produces conditions that make life possable. Discussion questions: What happens if two black holes merge? If intellegent life creats many tiny black holes...

If you look at a phase diagram, at high temperatures and pressures, the line between liquid and gas ends.

About force laws: inverse square produces ellipses, but it is not the only one. Harmonic spring law is where the force = the distance, so the farther you get the more force you feel, like pulling on a spring. This law produces ellipses where the sun is at the center, not at a focus. Another...

Given 3- bodies of non-negleble mass, are there stable configurations or not. for example, Will a planet (with non-zero mass) orbiting 1000 au away from two stars 0.1 au apart eventually leave the system if you give it 10^9999999... years; or is the system stable for a truly infinete time...

The simple reason: firing your rockets will add the same amount of velocity no matter where. But, kinetic energy is velocity^2, so the faster your starting velocity is the more energy you gain. example: going 3km/s your energy is 9 units. add 1 km/s and energy is 16. You get 7...

Supernovas were more common during the early universe because of faster star formation. Now they are rarer.
