meaning then that what we tell children has been true. the universe as we know it is growing and is as far as we can tell infinite

portion of it because of their composition have unusual spins on physics as we know them

what if in the realm of string theory the laws that govern physics down to the tune of the strings is slightly shifted in other places in the universe? more or less friction, light travels faster or slower, and new and unique forms of matter exist that in our part of the universe simply can't exist?

so while the universe as we know it isn't strange, it is not necessarily as old as we think, like humans, if you look at the population of earth without considering the dead you'd be inclined to assume that our species is only 100-200 years old, but we go much further back.

in that sense is there a way to judge the age of the universe by the structures left behind? like humans have cities and nations built upon the bones of the now long dead past do the current super structures leave evidence behind of their earlier periods? chemically it would be hard to tell, but if a group of stars seems to be growing out of what could have been the region remaining in the wake of a super nova then perhaps some of those regions can be dated further back than the existing starts would show.

it would also be interesting to hear that the strings if the theory is correct can be retuned, even if so slightly causing massive repercussions in the physical world we inhabit, if the force of gravity was tuned slightly stars and planets would decohere, the size of things would be altered, if the nuclear forces were to change perhaps atoms would be the size literally of beach balls planets or even stars.
