comment Could a finite amount of space in the universe exist without time?
@JonCuster: There is also a "custom comment" field that you could have used. No canned comments being applicable does not mean you should use them anyway! Quite the opposite. :)

comment Could a finite amount of space in the universe exist without time?
@JonCuster: Yes. On Stack Exchange, an answer that you personally believe to be incorrect may be denoted by a downvote. The "not an answer" flag should only be used for something that does not attempt to answer the question, such as a follow-up question or a "thanks" message. (If nothing else, imagine if flags instead of votes were used to express dissatisfaction with a post. Suddenly votes have no meaning and the entire democratic way of denoting post quality breaks down. Now it's just down to one guy who declares an answer incorrect and flags it for deletion? No!)

@JonCuster: It is an answer; it's just an incorrect one.

comment Short of collision, can gravity itself kill you?
"All parts of your body are affected same and in the same direction, therefore it cant tear you apart." Nope

comment How am I able to stand up and walk down the aisle of a flying passenger jet?
"I needed 500 times the energy to do it." No, the plane's engines did that for you. You felt it as acceleration on takeoff pushed you a little firmer into your seat.

comment Does quantum mechanics play a role in the brain?
@CuriousOne: I'm just saying, science involves dismissing ideas (when it's well-founded to do so), but never dismissing people.

comment Does quantum mechanics play a role in the brain?
@CuriousOne: Firstly, I didn't get any responses at all, seeing as it's not my question. Secondly, I was referring to your casual dismissal of the cited arguments as "questionable philosophical ideas" and your implication that they were put forth out of greed for booksale money rather than anything else.

comment Why can't the human voice produce a Shepard tone?
@Soren: I'm interested to meet the human who is able to produce only one tone at a time. That would be remarkable!

comment Does quantum mechanics play a role in the brain?
@CuriousOne: That's an extraordinary way to talk about ideas with which you disagree. How extremely rude. Talk to me when you can explain human consciousness.

Light doesn't "emit" anything...

comment Questions on the movie Gravity (2013)
Of course that wouldn't really have been a "portrayal" at all in any useful dramatic sense :P

comment Could gravity accelerate light?
@Mehdi: Two different ways of modelling the same thing. It's all abstractions when you get right down to it.

comment Why not dilute radioactive waste?
@borilla: Right but not in the way that the OP's imagining.

comment Why not dilute radioactive waste?
It seems the OP has invented a principle of conservation of radioactivity :) Regardless, the premise of the question (and thus the assertions contained therein) is just fundamentally wrong so I'm afraid I must downvote.

comment Will the box move?
Case 1 is simpler than that - the man is pushing forwards with his hands, using the floor of the same object (pushing backwards) as a counterweight. These cancel out. He's literally pushing and pulling the same thing the same amount. You don't need to go into the whole "the floor is pushing back" thing, which I find rather unintuitive and I'm sure I'm not the only one!

comment Where does the energy go in a rocket when no work is done?
I'm basically quoting my mechanics 101 material. I don't see how applying additional force to a body can result in no net velocity increase. That seems ridiculous to me. Just because I push a body sideways doesn't mean it stops going upwards so fast. I'm adding to the velocity, not simply redistributing its component vectors.
