Earth Speaks: index

First, a question.

If you're traveling at the speed of light and you turn on your headlights, do they do anything?

If you don't know, we don't want to talk to you, anyway.

We should send them the measurements (mass, distance, time, velocity) of our bodies, the earth, and the rest of the celestial bodies in our solar system in term of Planck units.

We want to know ALL about Physics.

Tell us what you know.

Does P=NP? That is to say, if a solution to a problem can be verified quickly by a computer (say polynomial time) can the problem also be solved quickly by a computer?

Also cold fusion would be neat. You guys got that?

Room-temperature superconductors?

Grand unifying theory? Quantum mechanics is... inelegant at best.

Strong AI?

Self-replicating robots?

All that stuff would be good. Anything would be helpful.

1. About four-fifths of the substance of the universe is a type of "dark matter" whose presence we infer but cannot detect directly.

a. Can you tell us anything about it?

b. Would it be dangerous for us to have this knowledge now?

2. Most of the energy of the universe is "dark energy". Can you tell us anything about it? It seems to be pushing the universe apart, so that one day we will not even be able to receive light from outside our solar system.

3. Can you still hear me?

Certain neutrinos (def. ...) were recently observed travelling faster than the speed of light. Were our measurements wrong, or can anything be faster than light?
