The worlds in Charles Sheffield's Summertide. 2 earth like planets, one covered by water, the other rocky, orbiting each other and having periodically pretty dangerous alienations with their star and big planets in their system, causing big quakes and tsunamis. The scenario is great, but very dangerous. » 4/07/15 1:54pm 4/07/15 1:54pm

Will be focused solely in the bad (micro-)guys or all of them in general? We depend on them, trying to nuke the bad ones harm the good ones too, including the ones that do a better job controlling the bad ones population and the ones that make us live healthy.

The distance problem is also important. We detected exoplanets (where the star is very visible). Even if they are shining bright if they are far enough (as by very far most of the universe is) we won't be able to detect them. And in the other direction that happens too. We are in a 200 light year bubble where our… » 3/28/15 9:18pm 3/28/15 9:18pm

There is just no time to go to the future and stop the wave, so the… » 3/19/15 6:48pm 3/19/15 6:48pm

Destroying the moon was pretty easy for the old man in Dragon Ball against Goku in monkey form, and trivial for Piccoro at the start of DBZ, in fact Vegita tried to destroy earth a "little" later when decided that wouldn't be defeated. And by then they were at the deep bottom of the power level scale compared with… » 3/19/15 4:48pm 3/19/15 4:48pm

Science (and scientific units) are not about (sometimes subjective, and depending on culture) human feelings. Making temperature, and far more fundamental units, dependant on water make the whole system consistent. Mass and temperature metric units are combined in the calorie unit (that is amount of energy to raise… » 3/16/15 7:43pm 3/16/15 7:43pm
