comment How do you calculate the intensity of light around the focal point from a focused collimated beam of light?
What experiments have shown that light cannot scatter in the way that I would like? I have seen two intersecting spot lights in the sky in cities at night before and where the light intersects shows a region that is brighter. I think at the focal point, light beams are intersecting too! Why won't this work?

I have thought of holography, but I don't want to make an image that is confined within a rotating screen or something that can hurt someone.

You might want to look into gravitational waves.

comment what cools bottle of water faster: ice or snow
I didn't say that the water will stay at 4 degrees C. You should have a (or two) at what I wrote and didn't include. Yes, its obvious that the water will not stay at that temperature. Why are you pointing out something so trivial and blaming me for not knowing physics?

comment Does spacetime really exist in quantum gravity?
I think the question should be restated to be more specific because "there is a lot to be said on this topic."

comment Do spacelike singularities really exist in quantum gravity?
How are you defining "real" and "memory"? Also, just because there are no direct records of something doesn't imply that that something isn't real. Also, Indirect records or indirect evidence is still evidence.

comment Does spacetime really exist in quantum gravity?
If there are no observables in quantum gravity, then it means that the theory of quantum gravity is useless. It does not imply that space time does not exist or is an illusion. I vote to close this question because the question doesn't make sense.

Add water at 4 degrees C. You'll get water in its most densest form, so you have the most amount of molecules touching the bottle as possible.

comment Entropy and how it applies to everyday activities like eating food
Thanks anna! Your just as cool as Luboš Motl. He's my idol. I hope he sees this compliment of him. Now your my idol too.
