Yes something like that... And because we reside inside this infinite universe, it makes us infinite small in comparison... And the question is, something thats infinite small... does that exist?

No not singularities, although they cannot mathematically exist... It was more the term "infinite"... Like if you say... this object is infinite small... does that mean that the object does not exist? And what I meant was if you put any object (regardless of their size) inside something thats infinite big, would that make them infinite small? And if they are infinite small, does they exist? Pardon my english... it's not my mother tongue... hope you understand my point...

This is a very old thought that troubled me when I was about 10 years old. Today it suddeltly popped in my head again, and I thought it would be funny to hear any reactions on the topic. It goes like this... The 3 dimensions of space that the universe is expanding in, seems to be infinite in lenght.. This indicates that even though matter in the universe only has travelled as far as it has (our measurement of it's size), the universe is infact infinite in size... If the universe is infinite big, does that not make everything that reside in it infinite small ? Something thats infinite small could that equal none existant?

Yes thats a good point... and why have nobody (what we are aware of) not visited us from the future... I would imagine that if time travel to the past was possible, it has to have strict rules and be conducted in a manner that would prevent us from interfering with the past. All matter may have a time signature that prevents it from colliding with matter with another time signature... Like the past can not interfere with our time... We would not suddently read news in the history books - that would be odd.. Who knows if we are actually in the past, and the future we have not yet reached is being acted out as we speak... acted out in the exact 3 dimensional space as we occupy.. maybe right next to you, even on top of you and through you... This whole theory would not seem to work, because it suggest that if you cannot see and collide with matter with another time signature, then you were to find the absolute definition of nothing if you went travelling in time... So maybe this is another thought we can rule out...

I can't see that happen, first it would mean that our lifes are dictated by a preset fate that could not be changed, and that the travelling in time was set out for us to do if we did it, and we would have lived our exact same lives an infinite times - and will to the end of time.. - the explanation reviels itself by reading this post.. I don't see time travel this way because it would mean that the dimension of time is bent in a loop like manner, this would indicate that the expanson of the universe would suddently start as the big bang once again with the blink of an eye. Or the universe would expand then later collaps in the big crunch until reaching the point of a singularity then start the precise same big bang again resetting time, exploding in the same way - and every particle moving in the exact same way and so on (this was what i ment in the intro - with predictated fate). This seems very unlikely next to a new big bang continuing time where it was left, exploding in a new way, particles and atoms flying in random ways and setteling in (most likely) new ways. The universe have always seemed to have acted in a rational/orderly way.. excecpt from singularities where everything stop making sense.. What happens there could actually prove you right!, but then again it could prove everyone's wild ideers right... The other possibility would be that as you travel forward in time you would first pass points in the future time, and as you travel on you would pass the same points once again, then pass the point where you first started out, then passing points in the past.. This would indicate that the expansion of the universe would end in the big crunch, and that the big crunch would some how reverse the the arrow of time to make eveything act in a reverse way... like first you die, then you get younger and younger until you are born and so on.. but then again you would only be able to go as far back as to the time when you were born (actually to the time when you entered your timemachine,... but then you would have seen the future)... If you then somehow find a way to become static, so that it was not you moving in the in the dimensions of space and time, but they were moving for you to see from your static place at a safe distance, you would be able to watch as time enter "your" past from your point of view... Right now it seems more unlikely than likely, because it somehow seems very disordered in a universe that tries to make order.. Pardon my english... it's not my mother tongue... hope you can understand my view on the matter.
