comment How is it possible that we see light from shortly after the big bang?
@RonMaimon: Hmm, yeah.. I couldn't understand what the OP was exactly trying to say, but it seemed like something just cooked up randomly.

comment How is it possible that we see light from shortly after the big bang?
even if it's mathematically rigorous, it still may not be accepted, take note, since it's still a "I have a theory" question. Though you may have a chance, depending on your edits. :)

Just a note for your future reference: Mathematical rigour is pretty necessary. Just an idea that is a bunch of arbitrary assumptions is extremely insufficient--If it was this easy we'd have had a TOE long ago.

Welcome to Physics.stackexchange! Unfortunately, we like questions based on established theories, and don't really encourage I-have-a-theory-please-check-it questions. Especially non-mathematically rigorous ones, Additionally, your question is very unclear in its present form.

comment Black hole no-hair theorems vs. entropy and surface area
@Ron hmm, yep.. Didn't occur to me (though the question still holds no matter how small the difference is)

comment Particles for all forces: how do they know where to go, and what to avoid?
"Thus it is not a matter for "knowing" but a matter of "being"". Well said :)

comment upper critical dimension in field theory
@PanAkry : Do you know that you can "accept" an answer by clicking the green tick next to it? It's not necessary if you're not satisfied with the answer, but please go through your questions and check if there are any that have correct answers in need of an accept. Thanks!

comment Addition of a neutral electrolyte to water— how can it increase conductivity?
I just realised that this doesn't answer the full question--By kohlrausch law, the nitrate contributes significantly to conductivity. But here, I can't see why.. I see how sodium contributes. :/

@VladimirKalitvianski: No, it means that the rocket accelerates. I'll clarify that, one sec. Thanks!

comment Why is this charge distribution in correct? Capacitors in parallel and series
@jak look at my wires explanation. Here, you have one wire threading through $C_1,C_2$. Current goes in one end and out the other. No other inlets/outlets. So series. Just check if an ant walking down one end is guaranteed to come out the other, and will pass each component exactly once during its journey.
