A team of physicists is claiming to have coaxed sparks from the vacuum of empty space




why do you think they would call it sparks?
sparks are usually tiny pieces of something like metal.

electricity can cause sparks to fly off but the sparks or arcs
such as in welding are actually carrying tiny pieces of metal
with them.

so I suppose that the sparks are made of some type of material.

it may be that the electronic devices are breaking down
and this is where the sparks are coming from.

personally, I highly doubt that anything is comming from the vacuum.








3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
