CFC concentration in the atmosphere has only gone down since the Montreal treaty so it's still a success so far. (edit: I should have said "since 2000", the treaty was a phase-out to zero emissions by 1996) What happened was

Note that I said "exchange with fiat/crypto currency pairs". An exchange can certainly be crypto-only, but that's not what Kraken does.

Kraken is an exchange with fiat/crypto currency pairs, they have to interface with both worlds by definition.

Note that we're already moving around the sun at 30km/s. Or at 230km/s around the galactic center. Or at 368 km/s relative to the CMB rest frame...

Kinetic energy is relative to some inertial reference frame. You can pick any reference frame you want and each will give you different numbers, but conservation laws should still hold in each. Addition of kinetic energy is pretty unintuiti

I thought that was implied by the description of the EM drive of "X kilowatt for Y newton". But I guess the effect could indeed depend on your speed relative to some special reference frame, like that of the microwave background.

If you could produce a constant force (and therefore constant acceleration) for a constant power use, then both speed and the total energy spent would rise linearly with time. This is in conflict with the fact that kinetic energy goes up wi

A dump of coal ash will contain high levels of lead, mercury, cadmium, chromium, arsenic, and selenium. Which will either slowly leach into ground water and water ways (sometimes abruptly by dam failures) or must be kept contained forever.

I think the concerns around nuclear waste storage are a little overblown. A lot of nuclear waste is stored on site, which is an indication of how incredibly little of it is produced. Compare that to the hundreds of millions of tons (!) of t

OK, I'll bite. What do the facts say would happen when a brown dwarf passes through the inner solar system? Is the ejection of planets implausible?
