    Once every ten million years a fly alights on the ball.

    When that ball has worn away to nothing by friction from the fly - infinity hasn't even started yet.

    The steel ball will have long disintegrated from entropy before the fly can take full effect, but I get your point. :)

    That reminds me of a Buddhist reincarnation story. If a large mountain was to be stroked with a fine silk cloth once every thousand years, the amount of time it would take for the mountain to be worn away flat is the amount of time it takes to gain a precious human existence. (ie rare)

    They loved their ginormous numbers in the old days. The Vedic and Buddhist scriptures are full of shockingly long time frames. I am sure other world cosmologies contain big numbers too. A single breath of Brahma or Vishnu, for example, takes about 310 billion years, and each exhalation creates billions of Universes, which are demolished on the inhalation (expansion and contraction a la Big Bang). Maybe we just lack imagination with our puny numbers, relatively short cosmologies and conceptions of spans of time? :)

    It can fit the guests of an infinite number of buses each of which can hold an infinity of people and still have rooms over.
    So, you're saying it can hold more than sixty characters?

    Here's my key....philosophy.
    A freak like me, just needs infinity....

    Some mathematician didn't believe in infinity, in his mind there was some massive number and the next number just rolled over to 0 .... total ****e really, i don't know how he escaped the argument that no matter how big you could +1 to it ... .

    I know it is tough to keep track of that stuff, so here goes:

    The Space Stone - Blue - AKA The Tesseract. Now with Loki.

    The Mind Stone - Yellow - Was in Loki's scepter. Now in Vision's forehead.

    The Power Stone - Purple - Was in the orb Quill took at the start of Guardians. New being stored at Nova Corps (the planet at the end of that film).

    The Reality Stone - Red - AKA The Aether. Was in Natalie Portman (giggity!). Currently being stored by The Collector (Benico Del Toro).

    The Time Stone - Green - Currently in Doctor Strange's Eye of Agamotto amulet.

    The Soul Stone - Unseen so far. Probably being held in Wakanda.

    Is that relatively recent, how long ago were they talking about multiple universes? Or is that a modern interpretation?

    He’s saying that the expansion due to the Big Bang will slow or stop and gravity will continue to exist as an attractive force and therefore the universe will contract.

    Perfectly sound in theory but the observations don’t show that the expansion is slowing, instead it is accelerating.

    If the current observations shows that expansion is accelerating then that just means the universe is still in the process of exploding.

    Eventually it will slow down and stop followed by a contraction.

    But the human race will not be around to see that so i really wouldnt worry about it.

    The universe is estimated to be 13.8 Billion years old.
    The earth is estimated to be 4.5 billion years old.
    The earth has held life for around 4 billion years.
    Humanoid species have existed for around 6 million years.
    Homosapiens (current humans) have existed for about 200,000 years.
    The industrial world has only existed for ~250 years!
    The internet was only made public 27 years ago!

    Time is huge. Humans have only existed on this planet for 0.005% of earths existence. We could be wiped out and a new species equal to us could evolve in another 0.005% of time and thats still only 0.010% of the time that this planet has been capable of holding life.

    Hard to say. I am no expert. The writings in for example the Vedas and Puranas were based on much older oral traditions and the writings are being modified since early centuries CE to several hundred years ago. They had cool ideas aka philosophies based around maths, investigating things like zero, one and infinity from a very long time ago. Can't google and type on this ancient phone but you should be able to find stuff.

    That’s not the case. For something to keep accelerating a force must be continually applied.

    The inflationary force from the Big Bang has long gone. Physicists now call this hidden force/energy Dark Energy.

    Eventually it will slow down and stop followed by a contraction.

    That’s not certain either.

    You know I think everybody knows that. However you don’t know how long humanity has. We remain at risk on this planet. If we get off we could see out a few billion years. Probably we won’t.

    It's just a very big number

    Hang on a second ... it only had one corridor ...
    so there could also be a hotel with infinity corridors on each of its infinity stories


  • Registered Users, Registered Users 2 Posts: 4,466 ✭✭✭chupacabra


    All numbers are made up, the sun doesn't give a fcuk what age you are. How many characters bis that? Sixty or six squilion, it doesn't matter.

    Listen to Snap!

    I believe I remember reading once that you were from Donegal. I recently drove from Kerry to Donegal for the first time. Very nice county you have there.

    Something that came to me while driving my car this afternoon... When we talk about the age of the universe, and infinity, we're making a very big assumption, that time exists at all.

    There is decay and entropy, but time?


  • Banned (with Prison Access) Posts: 2,488 ✭✭✭pleas advice


    Time is what prevents everything from happening at once.

    Time is what prevents everything from happening at once.

    It also stops me bumping into myself around the apartment.

    And time is pretty much unidirectional too.


  • Moderators, Recreation & Hobbies Moderators Posts: 4,709 Mod ✭✭✭✭Hyzepher


    Think about an infinite event within a finite time period.

    Lets say you have the ability to travel as fast as you want.

    I ask you to run 100m in exactly 20 seconds. The only condition is that you continuously run half the remaining distance in half the remaining time. The first 50m would be run in 10 seconds, the next 25m in 5 seconds and so on.

    Within these conditions you would never reach the finish line yet you would never exceed the 20 second time allowed.

    As far as I know there's no law in physics that states we have to be going forward in time, we could be going in reverse to the time we think we're going. But, why can't we remember tomorrow in that case - can't remember what the supposition for that was :pac:


  • Closed Accounts Posts: 6,748 ✭✭✭Avatar MIA

    We can only experience one exact moment (right now) - maybe that's the only moment that exists and every other moment is just a fake memory (Trump Time TM) of what we think is a different time, but is simultaneous :P

    No, your two conditions are just impossible to do together.
    It's like saying I want to you cross the line and not cross the line. You can't do both.

    It's like saying God is all powerful and asking God to create an object he couldn't move.

    It's really more of a recipreversexclusion, that is to say, a number who's cardinal value is defined as anything other than itself. As such, it is mostly Somebody Else's Problem and will probably bugger off in due course if left alone.

    Is this to do with Zeno Paradox?

    Thermodynamics pretty much drives the Arrow of Time.

    Depends ,

    are they more comfortable for running the 100m than Dr Martens Paradox ?
