A second characteristic of our time is the prevalence of nationalism. This is still spreading, affecting new communities, more peripheral regions and so-called backward peoples.
Nothing can create something all the time due to the laws of quantum mechanics, and it's - it's fascinatingly interesting.
General relativity predicts that time ends inside black holes because the gravitational collapse squeezes matter to infinite density.

Nuclear energy is a baseload - meaning it's power that you can run any time you want, day or night - and carbon-free.
I don't want to be the embarrassment of the galaxy to have had the power to deflect an asteroid, and then not and end up going extinct. We'd be the laughingstock of the aliens of the cosmos if that were the case.
As long as the wrong people hold power, how can the right political climate even arise?
