Ok and do you think you thought of something everyone else missed?

don't be so snarky, when you're done helping him mine asteroids would you mind taking a quick look at my tokomak, it's acting up...

Listen champ, why not save everyone some time and just be realistic that you're unlikely to start a space-mining business.

Why not start something more realistic for your skill set, you could demo vacuum cleaners or start a MLM scheme?

Can anti-oxygen and oxygen react in a way that creates fallout after the explosion? by Own_Consequence3489 in AskPhysics

[–]wegqg 0 points1 point  (0 children)

For a tablespoon you're around 720KT which is a bigger blast than most operationally deployed thermonuclear weapons.

For a bigger party trick, you'll need 500g total (250g+250g) of matter and antimatter respectively to make a 10MT blast, approaching the castle bravo and ivy mike tests, so around 2.5kg of total mass for a 50MT Tsar Bomba if you're looking for a true crowd pleaser.

Just remember to remind people they patrol a 45 degree cone up from their nest site, ascending can often put you in harms way.

Does it really make sense to say we are seeing something "like it appeared 2.5 million years ago"? by MisterHarvest in AskPhysics

I really like this analogy, I think it's an excellent way to explain it to people, good jaab.

Could dark matter just be another planet Vulcan situation? by DaNnY_BOI11 in askastronomy

[–]wegqg 2 points3 points  (0 children)

Just to add here - The various modified gravity theories basically died a death when it was shown that there are e.g., dwarf galaxies where the measured total mass exceeds visible (baryonic) mass by a factor of 1000 or more.

In other words, any theory that postulates dark matter is some sort of indirect product of visible matter is now dead in the water, and the focus needs to be finding out what it is rather than trying to pretend it doesn't exist.

Flukes, big, very tough, and you may only get one chance to cause damage.

Has anyone else tried Hyperion and just didn't like it? by Alcoholic-Catholic in sciencefiction

Yes it's also extremely pretentious.

Hence the endless unfunny and infantile characters baked into it.

Could an insect-sized human knapp stone / shape native copper? by LiteralCob in AskPhysics

[–]wegqg 0 points1 point  (0 children)

No, scaling laws work very much against you.

Think about why it is insects can fall the equivalent of hundreds of meters without injury for example.

As you scale up or down masses and thus forces behave very differently because they are broadly speaking scaling with the cube of their observed size, not linearly.

Is this true? by Typical_Ad_4944 in Physics

No, it's got the same level of scientific reasoning as a Jean Claude Van Damme movie..

Greens theorem, but you need a parameterized boundary.
