From the mind of my child; comes simple answers; to complex questions.

Q: What is the source of the dark matter; of the universal fabric? 

A: Star smoke! 

Q:What is the cause and the source of gravitation and gravity? 

A:The photon; and its spin through the universal fabric. 

Q:What is the cause of the expansion of the universe? 

A:All of the bow waves of the photons pushing out into the universe. 

Q:What is the reason for the high surface temperatures of the stars? 

A:The agitation and friction of atoms of plasma trying to escape from the gravitational spin grip; at the surface of the Stars! (The tearing apart of atomic velcro.) 

Q:What is the origin of time? 

A:The creation of matter; is the evidence of change, and is the proof that time exists and has passed!

Q:Does time have a particle? 

A:Yes, the photon is the particle of time! Every photon created; creates new time; more time; matter is the proof of the existence of time, and the cause of change.
