the airforce took the SR71 off their opperational lists, but it is still flying for the CIA and NASA with AF pilots and maint people.

you can shield small magnetic fields, computer hard drive motors.

Everyone knows our galaxy is just one cell of a higher being, with the other galaxies being the other cells. The Milky Way happens to be the cochlea of you guessed it, God almighty himself.

If it has momentum, it has energy. It can't have energy if it doesn't have mass, even if it's incredibly incredibly tiny.

Because light travels at the speed of light, all of it's mass has already been completely converted to energy.

Because relativity shows that mass increases as velocity increases, then if a photon (which travels at the ultimate speed) had any mass at all it must be infinite.

Therefore at its natural state, velocity=c, the photon's mass must be zero.

The first link actually calculates the mass, but it is beyond me to confirm it.
