Recent 2 Problems

Were a part of the “scientific war”. Not so much a better known cultural war,  despite the fact one may see them as that, too!

Two corner stones for the Climate Change narrative are obviously shaky. Our planet was once warm, thanks to its faster rotation in the first place. And the locally rising sea is a bulshit as well.

These basic facts explains a lot!

And Another Physics Problem

The one I talked about before, but it is very obscure, even unknown on the whole World Wide Web.

We have two equal stars, A and B. Then we have a planet called X in the orbit around A, and a planet called Y around the star B.

Everything else equal, except for the rotation speed of both planets. Planet X rotates 20% faster than planet Y. The question is, which planet has a higher average surface temperature.

Physics Question

Fast receding galaxies, is their metabolism  apparently slowed down due to some relativistic effect, or not?

For example, supernovae (type I, for example) should be dimmer, right?

And any other type of stars or whatever object do shine at a slower rate.

Don’t they?

Another Intermezzo Intermezzo Problem

The first one was solved by Oscar Cunningham and the point of the solution is that every probable black hole lasts for at least a million years longer, if you add just one hydrogen atom into it. Of course, a supermassive black hole acquires even much longer additional time with every hydrogen atom acquisition, or shall we say — a merger with a single hydrogen atom.

It is reasonable to assume, that our domestic SMBH’s lifespan is prolonged by 10^60+ years per second, due the regular infall. Assuming also, that there will be no Big Rip or something equally unpleasant for black holes in the future.

While we still don’t know the definite answer to the Intermezzo problem, here is another inter-intermezzo.

Are there non synthesizable molecules, which would be stable if they somehow managed to pop up into existence by magic or by some weird quantum fluctuation? (Non-synthesizable-repeatedly from chemistry/physics/mathematics/logic reasons.)

Intermezzo Intermezzo Problem

This one is easy, every physicist should be able to answer it.

There are two black holes A and B.

A is heavier than B by one hydrogen atom. Assuming that nothing will fall inside any of those two black holes in the future, the heavier one will evaporate by Hawking radiation  one million years after the lighter one.

Question: What is the approximate mass of those two black holes?

Physics Problem

Two equal, rigid objects A and B are dropped from high altitudes toward the Earth at the same time. Felix Baumgartner style free fall without any initial relative velocity against the planet. Somewhere in the Central Atlantic, both will splash.

Object A starts higher than object B and reaches the Atlantic first.

How?
