Is energy in vacuum real? How do we know that this energy that can be borrowed and returned immediately is real if virtual particles didn't exist then?
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?
Where does vacuum or zero-point energy come from? Does it add up to the total amount of energy in the universe? Does negative energy not exist? Can energy/matter be created/destroyed? If matter could be converted to energy, is it possible to convert energy back to matter? If energy can neither be created nor be destroyed, then who created energy? Energy can neither be created nor destroyed! Can this be proved wrong? Is it true that matter/energy actually can be created and/or destroyed? What is meant by true vacuum and false vacuum? What's the chance of vacuum decay happening to our universe? Does negative energy exist? If so, what is it? Will Virtual Physics be the physics of the future? If we are in space and space is a vacuum, why aren't we also in a vacuum? Can an infinite amount of dark or vacuum or gravitational energy be created with expansion? As energy can neither be created nor be destroyed, then from where does the universe get energy to expand? Is the existence of dark matter and dark energy confirmed or just theoretical? Can energy be created in a non-energy environment? Is the law of conservation of energy false? Are dark matter and dark energy: energy? Will humans ever create energy from mass or vice versa? Where is the energy for dark energy coming from? What exactly happens when energy changes from one form to another? What is meant by false vacuum? Could dark energy be caused by a reaction in the Universe? What is a virtual particle? If the Universe stops expanding, would that mean that dark energy became 0 or more (infinite) of it could still be created? When and how is mechanical energy not conserved? If universe stops expanding, would that mean that dark energy became 0 or more (infinite) of it could still be created? Energy can neither be created nor destroyed. So where does energy crisis come from? How energy can be created? Does an object moving in a vacuum lose mass?
