A black hole consisting of regular mass has an escape velocity faster than the light by gravity. Endothermic fusion reactions (from energy to mass) by:
and the pressure, due to gravity creates dark matter, which decreases the escape velocity by antigravity.
Tachyons could perhaps be black hole/Hawking radiation too. They are not solely faster than light, because their mass seems to be negative too.
We should maybe however try a comepletelly different approach. It could perhaps be like a 2 or 3 dimensional whirlpool.
Let’s check it out!!!
I can’t hold it. I meant a laser experiment with a strong whirlpool. Perhaps with factors like viscosity and flow strength. The refraction index as well.
