Can energy be borrowed from vacuum(to be returned immediately)? If this happens how do we know vacuum energy is real if virtual particles don't exist?
Are vacuum fluctuations an energy in a vacuum? Are these virtual particles? How do we know there is this energy if they didn't exist? Do they really exist?
What is a virtual particle? Does negative energy exist? If so, what is it? What kind of organism could exist in the vacuum of space? Does negative energy not exist? What's the chance of vacuum decay happening to our universe? What is space if not a vacuum? Do bacteria exist in space? What is meant by true vacuum and false vacuum? What is meant by false vacuum? If we are in space and space is a vacuum, why aren't we also in a vacuum? Is the vacuum of space filled with dark matter? What does "space is a vacuum" mean? Is 'empty' space filled with massive particles which are displaced by the particles of matter which exist in it and move through it? Will Virtual Physics be the physics of the future? Does dark matter really exist? How do noble gases exist in air? Is the existence of dark matter and dark energy confirmed or just theoretical? What are some of the current theories for which particle makes up dark matter? Do spirits really exist? Can an infinite amount of dark or vacuum or gravitational energy be created with expansion? How electron, positron and gamma photon created from vacuum? How ideal is a space vacuum? What are the chances of a vacuum metastability event hitting the universe in the future? Are dark matter and dark energy: energy? Could there be animals in the vacuum of space? Are subatomic particles visible? Vacuumed sucked space is considered nothing. Is nothing considered to be present when nothing exists? Or was it considerd to be expanded empty space? How are electron, positron and gamma photon created from a vacuum? How many elementary particles are there in the universe? What are dark matter and dark energy and do they make the empty space?
