I'm a retired geologist ... Know little about cosmology or quantum physics so will defer to others. Please excuse my rambling question. Something has always 'made me wonder' about the potential fate of the Universe. Almost all models predict either an infinite Universe or a Universe that undergoes some end or cycle that is hundreds of billions or trillions of potential years. Bottom line. The Universe is only 13.7 billion years old. The Universe, according to almost all models is not a hundreth or even a thousand...in some models a millionth...of its potential age. If there is an infinity then, 13.7 billion isn't a mote on a dot on a number line. The Universe is a baby. Barely getting going. 13.7 billion years is a blip in time compared to how old the universe could be at a random moment of time in its history. Throw a thousand numbers into a box and pick the number 'one' out at random...if it is the age of the current Universe, it would still be the equivalent to the number 'one' according to some models. That's always seemed a stretch to me. Why are we at 'now' almost at the beginning of time and not further along. Yes, the Universe has to be at some point in its existence. However the point that is 'now' seems the equivalent of a random chosen human being one day old...possible but highly improbable...one in tens of thousands. One would think that 13.7 billion years old would be somewhere further along a scale. Anyways...my question...are there models of the Universe that would put the Universe further along the percent of its life cycle? Is there a model in which the Universe has a finite life span of 20 or 30 or 50 billion years? Some age that makes 13.7 seem more probable to be 'now'.
