Guys I like science, I am particularly interested physics. Tell me some stuff you're interested in and why it matters. I don't care if you're right or wrong but it has to be based in reality. Expand my mind.

For example, attempt to answer a question like this:
Is there any feasible (even if incredibly unlikely) way of using quantum entanglement for communications?
Or
If you could measure all the variables in a system, could you predict any outcome of that system no matter how complex?
