Yes it does. "Throughout the universe, particles and antiparticles spontaneously form and quickly annihilate each other without violating the law of energy conservation. These spontaneous births and deaths of so-called 'virtual particle' pairs are known as 'quantum fluctuations.' Indeed, laboratory experiments have proven that quantum fluctuations occur everywhere, all the time."I think sensory is innate to existence. IOW all matter reacts to interaction with other matter.
Yeah I am not sure why something rather than nothing. IDK why this "spark" exists.
Edit: Why doesnt apply in this case and science cant tell us how.
Cosmologists have constructed a theory called inflation that accounts for the way in which a small volume of space occupied by a virtual particle pair could have ballooned to become the vast universe we see today. Alan Guth, one of the main brains behind inflationary cosmology, thus described the universe as "the ultimate free lunch." What's the Total Energy In the Universe? | LiveScience
