Do virtual particles and energy in vacuum really exist? How do we know if they exist if we can't observe them? Where are they?
Quantum Mechanics: Virtual particles are said to "pop out of existence". How can we know that something doesn't exist?
Can we create virtual particles? What is a virtual particle? How do we know that photons exist? Would we not exist if matter did not? How does anything exist? Does reality have to 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? Does nothing exist or does nothing not exist? 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? Will Virtual Physics be the physics of the future? Does the Universe exist? 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?
