1.
" Physics it first of all Vacuum. "-
say many of physicists.
2.
“The Vacuum has the lowest energy condition.”-
they say.
Such definition of Vacuum is not scientifically.
It sounds as the doctor - genecology will establish the diagnosis:
" She is approximately pregnant woman ".
Please, give exact definition of a condition of Vacuum.

"A vacuum is a volume of space that is essentially empty of matter, so that gaseous pressure is much less than standard atmospheric pressure." "A perfect vacuum with a gaseous pressure of absolute zero." Perfect vacuums are never observed in practice, and are a philosophical concept. Partial vacuums are those that still have some amount of gaseous pressure. The quality of any given vacuum is measured in units of "torr". There is no "absolute" definition of a vacuum. People just specify the pressure in torr.

Energy can be only transmitted in 2 ways: thru radiation and by molucules. Both r applicable on normal environment, but vacuum can only allow radiation cos there r no physical substance in it. Vacuum only allows non-physical transmittion like Gravity, light or heat which does not need a media to transmit. Pure energy.Therefore EN LV is lower.

A "vacuum is a completely empty area containing neither gases nor liquids or solids."
An empty crked bottle is not a vacuum sas it contains air.It can become a vacuum by removing the air by means of vacuum pump.

A vacuum is space without matter. However in practise space with very little matter surfices. Even space their is some matter just very little spread extreamly thinly.

It is an area of space containing no matter.
