Mathematical analysis and reasoning behind why our universe exists. Light warps around the universe creating the illusion of infinite space. Galaxies are hidden within our universe like a hall of mirrors, multiple copies within.
The chance of us actually existing is one in ten followed by ten zeros and then followed by a further 123 zeros.
An infinite number of parallel universes must exist, ten to the power of 500 with one followed by five hundred zeros ten times bigger than the odds against, so the evidence is overwhelmingly convincing for a multiverse theory.
The 'me' feeling is energy operating in the brain; space temporal logic to the observer. Discrete electrical pulses (pieces of information) quantised individual particles or electrical blips of data; these signal blips of data travel through the brain via electrical and chemical neurological pulses of energy; your brain interprets this chemical and electrical activity and these signals are processed to make sense of the outside world.
The universe is a vibrating wave function, this wave function collapses when a conscious observer observes the world, collapsing the wave function and creating particles of matter.
Matter exsts by virtue of a force that brings a particle in an atom to vibration, behind this force is finely tuned mathematics, at ten to the minus thirty three it's rather like observing an advanced quantum computer with vibrating pulses of information working like an advanced computation, this information is the matrix of all matter.
If you dive deep into the nature of matter you discover a play and display of not electrons but potential electrons; when you measure a particle you cannot predict it's location and vice versa. One analogy is when you look around you, everything you see with the expectation of seeing it, it's that exploration and expectation that's actually creating it, we think we're in control but we're merely here observing the journey.
