Yes, I'm aware that it is not the exact same scenario. The exact scenario Rees described would not have worked for the point that I was trying to make. In Rees' example, you have to actually measure the distance more than once. The point of my example was that you could use relativity to...
Apparent superluminal motion of astronomical bodies is a well known phenomenon, and people have been talking about it for over a hundred years. My example was based on the work of Martin Rees. The crux of the problem in both my example and in Rees', is a mistaken assumption about one of the...
I've been playing around with the Minkowski diagrams in order to understand them better. But there is something that I'm finding fundamentally really confusing. Let's say that you set up two transceivers 4 light seconds apart. And maybe they use normal luminal signals, or maybe they use...
Wikipedia has this interesting article about a physics "paradox" that Einstein came up with:
https://en.wikipedia.org/wiki/Tachyonic_antitelephone
It shows that if you were able to send a signal faster than the speed of light, then you could send a message back in time leading to a causality...
It's easy to find references which explain that the photon is the force carrying particle for the electromagnetic force (ie https://en.wikipedia.org/wiki/Force_carrier). Similarly there are force carrying particles for other forces, like W and Z bosons carry the weak force.
This has always...
One of my good friends is really big into photosynthesis and "synthetic photosynthesis", so he's been keeping me up to date on the latest breakthroughs. You're pretty close, but a little mixed up (though I'm not an expert either by any means). Most of the latest researching had been focusing...
BTW, if stomach acid destroys your supplement, you just need to find a supplier that uses an enteric coating. From wikipedia:
"Most enteric coatings work by presenting a surface that is stable at the highly acidic pH found in the stomach, but breaks down rapidly at a less acidic (relatively...
Um... sorry to burst your bubble, but permanent magnet motors work. They're just not terribly useful b/c they don't work the way that you would think, and they don't end up providing very much useful work compared to the amount of energy it takes to create the stupid device to begin with...
