Woah.
Whoa*
Its cheating if you ignore physics and its pointless to create rules for that which is admittedly impossible, and when the video shows steps that breaks its own rules.
Give me an alternate universe in which physics are decided by me and Ill make a 50m^2 neutron star that is light as a feather. And can fly. And dance. Oh and it will be sentient too, because Id need a friend in that utterly fucked up world.
So yeah. Not amused
