Seems to me that it would be quite common, depending on the time frame you're thinking of. Sure there's a lot of space there, but there are a lot of stars as well, and they all have plenty of gravity to pull them towards each other.
If you're thinking of the time frame of a human life, then...
Normal boolean logic works with two states; true and false, which works fine with today's computer systems, which work with 1's and 0's.
However, I'm working on a new type of computer (Just need to figure out one last part about the 'and' gate), which will have three states (--,|,+).
I'm...
The GIMP can do almost anything photoshop can (including edit .psd format images).
It also has the advantages of
1: You don't have to pay a lot of money for it.
2: You don't have to spend hours trying to get wine to work good enough to run photoshop. (The most complicated program I've been...
Ah, that's helpful! If nothing else, you've reminded me what book I read it in.
Also, you've reminded me that I've had the wrong particle in mind; I should be focusing on positrons, not photons.
This problem is an interesting one (at least for me), and I wonder if ya'll will have any insights into it...
Suppose two black holes were on a collision course with each other. As they get closer, their combined gravitational force causes them to accelerate. As they accelerate, due to...
If I were able to get a particle with mass to tunnel through a superconductor (for the sake of having a point, a long, thin, cylindrical one), would that mass's travel through the superconductor have the same equal-but-opposite-reaction effect as the same mass if it were accelerated to such...
I suppose that could only happen if the velocity at that time was infinite, as otherwise the vertical line would have an upper limit to it.
It would also mean that the velocity of whatever you're measuring just jumped instantly with no time for acceleration, which would be highly unusual.
In...
I remember reading somewhere about vacuum functions; where a photon strikes a particle, which produces a chain reaction that results in the photon being shot back through time to start the reaction. (Or something like that)
Now, since I've forgotten most of what I knew about this phenomenon...
