Feb 20	comment	Why is the universe so big? Note that your only referring to the observable universe, not the actual universe size. The actual universe size could be much much bigger than 80 billion light years across. The fraction that we can observe is smaller than the actual size.
Feb 3	comment	Is it possible to project a magnetic field at a location in space? billions, trillions, of optical tweezers all over the bottom of a spin stabilized object
Feb 3	comment	Is it possible to project a magnetic field at a location in space? Could powerful lasers pointed up at some object scale up the optical tweezers effect by creating millions of optical tweezers, lift an object upwards?
Feb 1	asked	Is there a stationary frame of reference?

Dec 14	comment	Does time actually exist or is there just a single stateful system being updated over time? Mitchell, any computational system can fake time loops, the system could return to a previous state or hold state within its system. I.e. it can be a simulation of a system which allows past, present and future. However, everything could be a simulation of course. However, it is still not the same as a system which has a real past, present and future.
Dec 13	comment	Does time actually exist or is there just a single stateful system being updated over time? I think its amazing that this is seen as a physics question physics.stackexchange.com/questions/2605/… which I would consider a biology question, but this question is not.
Dec 13	comment	Does time actually exist or is there just a single stateful system being updated over time? I mean, the stateful system I described cannot do time travel because it cannot go backwards according to the rules. ... well, I see a difference between the two systems. I had hoped others would see a difference.
Dec 13	comment	Does time actually exist or is there just a single stateful system being updated over time? how can time travel be possible in the stateful system I described? If someone time travelled backwards in time, although they are in a different "state", the people he left behind in the future are still going on with their lives. In this case, it is different to the stateful system I described.

Oct 9	comment	Could hydrogen liberated from water provide lifting energy which exceeds the energy it took to liberate it from water I didn't finish explaining, - the helium originally gained energy when the planet was formed by the gravity of the earth as it was buried with other minerals/rocks. The energy gained in the balloon filled with Helium comes from the energy it took to originally bring it into this gravity well. Although helium is similar in some ways to the hydrogen/water idea I presented, the different is the energy gained came from somewhere known.
