Hi

As you know, the question of whether there exists such a thing as a
Absolute Vacuum, has been around since ancient Greeks...

The feeling was largely that "Nature abhors a Vacuum".

I am keen to understand, what is the take of modern physics on this
issue..

After alll, since our universe is flooded with light from all the
stars, all the intermediate space is filled with photons, and hence
can't be called a Vacuum.

Also fields, like Gravitational fields also carry energy/mass, and
they fill out the complete Universe, so there is mass everywhere,
hence no Vacuum.

Hope I am making sense here..

thanks for your comments
