Heisenberg1927

I would like to ask about the creation of matter with respect to the expanding universe.. I did some research and found a theory by Sir Jayant Narlikar: https://en.m.wikipedia.org/wiki/Steady_state_model His theory explains equilibrium of energy...with respect to creation of matter..... Hence i would like to hear your opinions and further increasing the discussion... Cheers

On the contrary, if another planet existed (by chance alone) far away from Earth(like billion light years) which had an intelligent species such as ours (at least that's what we call ourselves)...we would come to know about them after a billion years(assuming they tried to make contact)...which is too long.

I appreciate your reply...so for visualisation's sake can I imagine the universe to expand from every point in space/time..?

When a new planet or a star is discovered how do the scientists keep a track on their identities as there are billions of them?........(Just a question out of curiosity).....Does the observable universe keep on expanding....and if we can see more than 13.772billion light years(estimate) would that practically verify that the universe is expanding faster than light or is there anything else which proves it?
