Volume cannot be negative, cuz u cant go below -273.15 ^oC

Its just like saying mass cannot be imaginary because no information can travel faster than speed of light in vacuum!

{If u dont know, m=m_o/(1-v²/c²)^1/2 }

Now can you explain "physically" what imaginary mass is?

Lol, I don't think this has any physical meaning at all. Volume is the space occupied by a body, When volume becomes negative, what are you trying to say? More space is going to be created? LOL

See, questions like negative mass, negative volume are meaningless in a physical sense. Don't get confused by looking at the mathematics. Physicists first see things and then use the math, not the other way round
