` I don't believe we live in an open universe. At worst, some believe that the Big Bang was just a reincarnation...the endless cycle of expanding and contracting universes or realities. But even then, what higher order is responsible for that? On the other hand, there is also the distinct possibility that this reality has a beginning and an end. That being the case, numbers become finite hence not infinite.
Well, this is just another thread that has been hijacked by a troll, name of "Cerberus". Nice job, PF.
Pi is infinite, so is e and the fraction 1/3 expressed as a decimal. It isn't anything esoteric, just anything that goes on without stopping. I will agree that nothing we know of is infinite, however, as it is a mathematical process only, unless you want to propose something material that, when it comes to its end, goes on without stopping for as long as it had and then keeps on going still. Philp Jose Farmer in "The Library of Babel" proposed an infinite book . Everything ever written or possible to be written is contained in one page of it, and that page, when lifted, falls into an infinity of other pages, each as infinite as itself.
As a concept, yes, like space. The problem is that time may not exist as an actual thing, like space. One possibility is that Time and Space are both just ways we have of conceptualizing the relationships between things that are in the Universe. "Just a mathematical abstraction, my dear"; as Robert Heinlein put it.
The point is that we do not and cannot "Know" so we imagine possibility and a few claim they DO KNOW. This concept is fabricated as a defensive mechanism to either protect some dogmatic belief structure or ignorance of reality.
But that's not good enough. They have to go out and hijack other threads and pollute them, too? (*)(*)(*)(*) this place, it's a cesspool.
Uh....a thread called The Size of Space is not really going to have the intense laser like focus of most of the threads on here. Deal with it. And we're a septic tank, not a cesspool. We hide our stinks underground and clean ourselves fairly well given only minimal maintenance., though we're certainly not something you want in your living room.
Was that really worth posting? Don't you have anything intelligent to say? - - - Updated - - - Don't you mean 'just try thinking now'? Otherwise that phrase is meaningless. Actually, having just re-read your 'profound explanation' for the fifth time I've come to the conclusion that that's meaningless too!
Time is just a measurement tool created by mankind to explain why things not well understood are observed. A ruler is only a foot long because we say it is and the inches we use within are fabricated for convenience as well. Is a foot on a measuring tape the same thing when it is wrapped around a ball? We can try to explain things not understood and create theory and hypothesis till the universe ends.....we will not explain time accurately.
I think not. Time was invented to mark the passage of events. But Einstein believed time was real and that while matter and energy can be transformed, it could never be destroyed, which means forever - eternity- even if the universe collapses in on itself.
Obviously time is real...to us. Thus did we develop a name for it and use it to note event passage as you state. Einstein was as perplexed by what we call "Time" as everyone else, yet he understood that he could not completely understand it. Just as with "spooky interactions at a distance" could not be fully explained and still is not....just because we can name and note a thing does not mean we understand it. Time as a forth dimension indeed allows us to think more clearly about it and develop hypothesis.........yet it does not explain it.
We created a time scheme based on the rotation of Earth but this won't work on other planets in our own solar system...once we locate ourselves outside of Earth our time system becomes moot. A Rolex clock face on Earth will not be the same as the one Saturians use on Saturn. I can call friends in Singapore and be speaking to them 'now' and they are hearing me 'now' yet our clock times are very different. But if I make the same call to friends living in a solar system 10 light years from Earth, 'now' then becomes 'ten years from now'. All much too confusing for this old man...
