If the universe was infinte,and without boundaries would it be logical to conclude it would be infinite in time also?And if the universe was infinite in space/time How could this be understood in the antropy princeable,or laws of thermodynamics.Is there in a literal sense such thing as infinite?Either way you answer the question you have some explaining to do.And to my understanding if the universe was finite in time/space how could it be explained how something came out of nothing.I have read of subatomic particles pop in and out of existance,but the increment of time would be measure in nano-seconds.And there is nothing that would lead me to believe we live in the only universe.If our universe some how came into existance out of nothing by todays understanding of physics.Why would it be improbable for this advent or creation to have accured maybe millions or billions of times leaving untold number of universes perhaps from other demensions?
