Dear Forum,
Vacuum is classically interpreted as the absence of everything. But the quantum view of vacuum sees it as a bubbling, dynamic entity from which particles and antiparcles emerge for very short intervals of time.
Relativity teaches us that energy and matter can be converted into each other (is it correct to say that matter and energy are the same thing?)
So if vacuum has energy does it mean the vacuum is itself matter or does it mean that it "hides" matter? I am familiar with the Casimir effect (vacuum energy (with or without mirrors) is said to be infinite. This implies that the vacuum of space could be an enormous source of energy, the so called zero point energy)
From Maxwell equations, we know that the electromagnetic field is able to auto-propagate in the vacuum (it does not need a supporting medium likes sound does). Is it possible that the EM field interacts with this vacuum as it propagates or is this very unlikely?
Thanks,
