Do virtual particles in vacuum really exist?
Quantum Mechanics: Virtual particles are said to "pop out of existence". How can we know that something doesn't exist?
What is a virtual particle? How do we know that photons exist? Would we not exist if matter did not? How does anything exist? Is setting the state of a quantum particle a physical impossibility, or a technical problem that we currently don't have a solution for? If a thing didn't exist, would people spend a lot of time debating its existence? Are there phenomena that are literally unexplainable by science, or is the unexplainable merely what we don't know yet? Can something exist without time? Is 'empty' space filled with massive particles which are displaced by the particles of matter which exist in it and move through it? How many particles have we discovered? Does we exist? If a particle has no mass, how can it still be defined as a particle and not just a waveform? Can anything exist without time? How can I know that I exist? What are the chances that elements we don't know of exist on other planets or in other galaxies? What is existence? And do we know what it is? Or not? Why does reality exist? If God doesn't exist, how does anything exist? It is true that I don't exist? How do we exist? Why does anything exist? How do we know that dark matter exists? Do I still exist if nothing exists? Do we exist? What will not exist if time does not exist? If de Broglie's "subquantic medium" a sea of massive dark photons particles of matter move through and displace, causing it to wave? How can we prove that our universe is not a simulation? Do the names of the particles sound silly? Do elementary particles have shape? If particles carry information and the higher the energy the less it interacts, does it mean that higher frequency particles undiscovered exist? If so, could it be so high that it carries as much energy as the observable universe?
