Re: Science-based what-if questions

I presume that there will be a frame-dragging effect as it passes as well, that ought to have some impact on Earth's fabric as well, yes? Given that the total gravitational binding energy of the Earth is 1 ten-thousand-billionth of the energy of this electron, I would wager that if there is any inte...

Re: Science-based what-if questions

But from the Earths perspective, the electron take about a twentieth of a second to pass through, and while it does, it is under the influence of a solar mass worth of gravity at very close proximity.

So there is some scope for interaction, no?

Re: Explosives As A Reflective Wall

Originally it was a thrown satchel that did damage in a circle but it was hard to throw or plant the satchel far enough away without getting hurt. That's when we started asking about how to make the bomb deal more damage in one direction, like a claymores. Then I made the guess that a smart enough ...

You can take measures to change this, but eventually you start constructing a gun. This whole post was awesome.

Do Chameleons suffer much from predation? Perhaps they have little need for camoflage.

I have also heard that the way that the degree to which they can become motionless camoflages them from their prey (insects).

A railgun is called a railgun exactly because the "barrel" consists of two "rails" between which a large voltage is applied. Electromagnetic effects cause a large force to appear when this is allowed to discharge through the projectile. Or something. Ergo, there is no calculation...
