comment Can open, unsafe nuclear fusion reaction burn the atmosphere?
Isn't the solar core, with it's low power density, another argument against an out of control fusion event? Any fusion heat would quickly dissipate without a thick jacket to keep it hot.

comment Fusion plasma compression with liquid metal
General fusion should have mainstream, sound physics given the large investment in it. If it "fails" that would probably be due to engineering shortcommings and/or competition from a natural fusion reactor (cheap solar PV). The physics is the easy part, it should have been worked out by not.

comment Is it possible to create artificial gravity by magnetizing iron in the blood stream?
@Huge Allen: A frog would not float in a 10T human-size magnet because the dB/dx gradient would be less since the magnet is larger.

comment How can a metal heated at 600° emit thermal photons at 4000°+?
Our eyes are extremely sensitive to light, so 0.002% is still enough to see.

comment Has the photon both gravitational and inertial mass?
Which results are you talking about? The frequency IS related to the change in frequency. Time dilation is a relative number, i.e "twice as slow". If the original frequency is 1000Hz, the new frequency will be 500Hz. For 10000Hz it will be 5000 Hz.

No its not sci-fi, it is just a little confused.

Thanks for the thorough answer, and the experimental results that show a GUT scale inflation.

comment Does kinetic friction increase as speed increases?
I meant to say the box's motion does not matter, since it is much slower than the particals.

comment Melting and Boiling Points of Odd Materials
Brick will melt, as it is mostly an aluminosilicate so will be a lot like glass. Complex organic compounds like cellulose in paper will decompose before melting/boiling.
