.. and how did they get to be that way (ie: 'physical facts')? Magic?These aren't models. They are physical facts.
Our minds are capable of storing successive events ... (its a mystery, why that is so). Once you have a mind which does that, time instantly zaps into existence!Bradskii said:Let's say the sun goes super nova. So it undergoes change. So we can see it happening in time. Time therefore exists. Then the exploding sun destroys the earth.
According to you, time then does not exist.
Mankind uses the word, 'infinite', but mankind cannot comprehend the word itself, infinite.If the universe is infinite then anything possible is actual. I have two comments:
1. That must be right.
2. That cannot be right.
Pick a number...
I think that question was answered quite nicely by Alex Filippenko in the video in post #60.Infinite: limitless or endless in space, extent, or size; impossible to measure or calculate.
I agree its more productive to constrain it objectively .. otherwise there is no real possibility of agreeing on anything, when attempting to discuss it(?)klutedavid said:Your question belongs in the fiction category.
No edge .. just a cosmological horizon .. beyond which light hasn't had (nor ever will) have a chance of reaching us.God is infinitely so He alone can create an infinitely large universe. Seems pretty simple to me. I once saw a NASA official drawing that showed the outward expansion of the universe and a clearly defined "edge of creation"

If the planet is destroyed and there are no human minds remaining, then there will be no-one left to believe anything will there?So if the planet is destroyed, you believe time won't exist?

Same goes for the meaning of the concept of 'exist', of course.
Speaking of time.So if the planet is destroyed, you believe time won't exist?
Speaking of time.
What time do you scientists say it is now?
If something is infinite then it is not bounded. I am afraid that in mathematics the word, 'infinite', carries much the same definition.I think you're wrong about calculations and infinity. It's often used in physics and maths. Notwithstanding that the definition of the term in cosmology and maths is different.
There is a model I have in mind (right now) which predicts that time will continue. The definition of time in that model, is measurable. Whether that prediction 'tests out' after everyone is destroyed, is a matter of pure belief, conceived in the present. I choose not to believe in that model or its predictions.OK, I'll rephrase it....here's a statement:
If the planet is destroyed time will continue.
Do you agree with that statement or not.
.. so just change the context of your definition of 'infinity' there, to match what's going on then, eh?Since the real numbers between those two integers on the number line. Would represent the bounds for the set of those real numbers. A bounded set is not infinite by definition.
Impossible, real numbers are finite numbers. No matter how hard you push a finite number, it will never be a an infinite number. Simply because an infinite number cannot exist... so just change the context of your definition of 'infinity' there, to match what's going on then, eh?
After all, every definition in science is provisional and contingent on new observations .. (such as the infinite behaviors of the the reals between integers)?
Its infinite .. just a different context and thus a different .. cough .. cough, um: 'kind' of infinite?
The set of reals is regarded as 'uncountably infinite', whereas the set of naturals, is regarded as 'countably infinite', (in the math/axiomatic context), I think(?)Impossible, real numbers are finite numbers.
Redefine what you mean by 'exist' there then .. and the problem is solved, no(?)klutedavid said:No matter how hard you push a finite number, it will never be a an infinite number. Simply because an infinite number cannot exist.
Sounds like a workable operational definition there, then, eh?klutedavid said:Observe all you want, you cannot observe the infinite.
.. which is equivalent to saying science is constrained by the human minds practising it, no?klutedavid said:Science is constrained by space-time.
Not this again.Mankind uses the word, 'infinite', but mankind cannot comprehend the word itself, infinite.
Infinite: limitless or endless in space, extent, or size; impossible to measure or calculate.
Your question belongs in the fiction category.
You clearly do not understand what a real number is.If something is infinite then it is not bounded. I am afraid that in mathematics the word, 'infinite', carries much the same definition.
Mathematics is constrained within the realm of finite numbers.
You have probably been taught that between any two integers on a number line. There exists an infinite number of real numbers. Well let me tell you, that would generate a paradox.
Since the real numbers between those two integers on the number line. Would represent the bounds for the set of those real numbers. A bounded set is not infinite by definition.
You are confused.The set of reals is regarded as 'uncountably infinite', whereas the set of naturals, is regarded as 'countably infinite', (in the math/axiomatic context), I think(?)
Science is based on an ancient idea. I think the idea itself was first noted in India. Of course, it started as a philosophy. That one can understand the universe through observation.Redefine what you mean by 'exist' there then .. and the problem is solved, no(?)
