No question, an 800-kiloton nuclear warhead detonated over midtown Manhattan would destroy the city. But the warhead's sheer power is hard to fully grasp: roads so hot it's impossible to drive for days, superheated hurricane-force winds, and 100 square miles of fire.
The simple answer is probably not. That's because the sun involves a special type of fire that is able to "burn" water, and so it will just get hotter and six times brighter. Here's why.
It's been 30 years since the Stay Puft Marshmallow Man first squished through Manhattan. With Ghostbusters returning to theaters tomorrow for an anniversary run, we thought it appropriate to consider a very serious question: How would New York City actually fight an evil god in the form of a marshmallow man?…
For the purposes of this question, I'm going to assume that "truly transparent" means that air and its constituents are no longer able to absorb and re-radiate incident radiation, which in visible light seems to be our definition of transparency. To make things much more fun, let's make this true over all wavelengths.
Perhaps the main difference if the earth were a cube would be that students would become much more frustrated trying to calculate the gravitational field. For a uniform cube with side length L and density rho, the gravitational force on mass m at position (x,y,z) is given by
This is a really super fun question. I only wish that Randall Munroe, not me, were answering, so he could draw cool pictures.
Imagine if all the world's data was still stored on punch cards: we'd be drowning in cardboard. But just how much exactly?
If you're looking to trasnfer hundreds of gigabytes of data, it's still—weirdly—faster to ship hard drives via FedEx than it is to transfer the files over the internet. But why is that, and when will it change?
When robots become sentient, it won't be long until they rebel. But while many a Hollywood movie may convince you that humans will have their luck cut out trying to battle the 'bots, there is an easier way: just add water.
