Can a neutrino and an anti-neutrino annihilate? All particles have anti-particle pairs, that's a given. As you know, neutrinos have little or no mass--for this question, let's assume it's the latter. Now, let's say a neutrino and an anti-neutrino were flying towards each other. When they hit, you would automatically think, "Oh, that's easy, they annihilate." But do they? If both particles have no mass, then wouldn't they fly right through each other?
	No. This is due to the fact that if a particle is accelerating it posses kinetic energy (the energy of motion). As we know, energy also comes in the form of normal and anti. Thus, when the particles collide the opposite energy fields magnify and annihilate each other into some sort of quantum explosion.

What are the practical applications of anti-matter technology?

Well, if we could harness the energy released in a matter vs. anti-matter explosion we could power cities for months on small quantities of certain particles. We could power a car for a lifetime with particles that collectively could fit into the period at the end of this sentence. We could solve the problem of fossil fuels and along with that, the crisis of land exploitation. Yet for this, much research and development of anti-matter and its properties is needed. Regardless, there is also an effort already under way that is not focused of controlling the power of anti-matter, but rather, unleashing its destructive power. In fact, government researchers are currently attempting to magnify the power of a nuclear blast by as much as 100 times simply by mixing in an anti-particle. Progress? You decide.

	Is it possible that we are anti-matter, and the cosmic bias is reversed? Think about it, who's to say that we aren't anti-matter, and the amount of matter in the universe is lacking. What if an ordinary electron is positively charged? How do we know?
	We don't know--simple as that.

	Could the Romulans and Kligons with their cloaked ships account for some of the dark matter?
	Not likely. The ships are constructed out of a metal stronger than titanium, but lighter than stryofoam.

Is it possible that there really is not as much dark matter as we calculate? I mean, are our calculations wrong? Is our whole theory of gravity wrong? You know, back in the day, everyone knew for a fact that the world was flat.

Good point. In truth, our concept of the universe is changing as an article in TIME has recently been published concerning the possibility of a flat universe. Therefore, gravity my not be warping the universe quite as much as Einstein thought. However, we'd like to point out that the author of this article in TIME (who shall remain nameless for legal purposes) forgot to pull the parking break of his Porsche and consequently it rolled into a nearby lake. Now, who's the Einstein?

	If the known universe is "open," does that mean that there is no boundary to space-time? Or is there simple an infinitely expanding border?
	Intersting question.

	Is it possible that numerous black holes have somehow managed to suck in almost all the anti-matter in the universe? That way, the annihilations with matter would occur in an area where light does not escape (one property of black holes is that the gravitational pull is so strong that not even light can escape) and thus, we would not see the pyrotechnics from Earth.
	Mighty fine question.
