Yes but your burden is to show that it is more probable (not just possible)
No, because I'm not claiming that it's the right hypothesis. I don't need to, to dismiss WLC's drivel. I'm denying
his claim that it's impossible (not that that's his most significant blunder).
1 pick your favorite hypotheiss
Don't really have a favourite, by Penrose's
Conformal Cyclic Cosmology is neat.
2 explain how that hypothesis (if true) would imply that the universe is infinite in to the past
Wasn't really my point. Most of them don't have infinite pasts but also don't have first moments, but
Conformal Cyclic Cosmology does have an infinite past. Follow the above link or watch this:
That's actually part of a series of YouTube videos that take in most of the ideas I've mentioned. They're very good for pop-science, and amzingly good for YouTube.
3 explain why that hypothesis is better than say the big bang model (the universe began 14B years ago)
Again, not my point. The BB is the only theory based on accepted science. Its only problem is the singularity and your inability to understand that a finite past doesn't have the significance that either you or WLC think it has. I was hoping that a few other suggestions would help you understand that totally different view of time we now have from the one you cling to from the 19th century.
no sure what you mean but Yes, if you show that there is an actual infinit number of possitions between 2 points, the argument woudl fail and you would "win" the argument
What don't you get? It's a basic property of a continuum that it is infinitely divisible. Take two numbers, say 0 and 1. You can find a point between them, e.g. 0.5. Then do the same between 0 and 0.5, to get 0.25, do the same between 0 and 0.25, and you can go on doing this
literally forever to get an infinite number of points. Translate the numbers to distance, say metres, and you have the result.
In fact, it is provable that there are
more points between 0 and 1, (
continuum infinity) than
all the natural numbers: {0, 1, 2, 3, 4, 5.....} (
countable infinity).
Then explain why , develop an argument or provide a source, at this point it seems just semantics to me
Let's look at an analogy. Space-time is a geometrical manifold with 4-dimensions. So is the surface of the earh (or any sphere), with 2-dimensions. If we ignore 2 dimenions of space and compare the space-time with the surface of Earth, we can compare longitude with time and latitude with space. Except, it's not quite that simple, as there are many directions on the Earth that are neither latitude nor longitude. It's actually (sort of) the same with space-time, except every observer will see a different direction as time, so we need to define the
possible time directions and the possible space directions (as seen by each observer) so we end up with space
like directions and time
like ones, So let's do the same on the surface of the earth. If a direction that's closer to being longitude, we can call it a longitude
like direction, and similarly with latitude
like directions.
The main difference now is that, on Earth, there are
absolute latitudes and longitudes. This is not true in space-time; there are no absolute time and space directions. So space and time are even
less well-defined in space-time, than latitude and longitude on Earth.
All we are left with in space-time are spacelike and timelike directions, and even those vary from point to point. In fact, in extreme examples (like black holes), they swap over entirely, so a spacelike direction at one point can become timelike at another.
All we are left with is the space-time manifold itself and its geometry. There is no universal time that applies to all of it. The way we calculate the 'time' back to the BB is using the time of an impossible notional observer, that emerged from the big bang as was literally unaffected by anything but the expansion of the universe.
Can you see now that it is only the manifold that exists, and it has to exist
as a whole, because different observers see different slices through it as space and time? It cannot 'start to exist' because
unless it all exists, we cannot account for every observer. There cannot be a universal past, present, and future that applies to it all, so it has to
just be.
You may be more familiar with the idea of 'eternalism' or the 'block universe'. This is basically the model relativity forces us into. Past, present, and future all have to exist together in order for them to be relative in the way required.
