Kalam Cosmological Argument - Part 2 - William Lane Craig

[Intellectual4God]

dang what a long video, that blew me away i have to say i learned a lot, but out of the 42minutes theres one thing i wanted to go back and look at because i couldnt remember and it would be hard to find

is space potentially infinite, actually infinite, or finite

also

the universe is potentially infinite in volume correct?

[vincyjojo1]

Craig's argument is wrong. A hotel with infinite number of rooms could accommodate all the guests including potential guests. You could never have 100% occupancy in a hotel with infinite number of rooms.

@vincyjojo1 You're not listening to the audio close enough are you. We're talking about actualy infinites, genius.

[vincyjojo1]

I do understand the difference between actual and potential. Craig says that actual does not exist. To demonstrate that he uses Hilbert example. What I am saying is the the infinite room analogy is absurd.

Let me ask you a simple question. On what basis Craig says that actual does not exist. He might say that there is no evidence for the actual infinite in our natural world. Is absence of evidence evidence of absence? The "logic" I used above is Craig's own favorite phrase!!!!

@drcraigvideos time that is potentailly infinite equals space which equals your actual.

[TheCopaceticMan]

How is subtracting an infinite from an infinite a contradiction? That sounds to me how infinite sets work. I don't see a contradiction there. Any further elaborations?

[Satarack]

@TheCopaceticMan An Infinite set is not an actual infinite, it's a potential infinite. You have to understand the difference between these two things first.

A potential infinite is a set that goes from i to N where N=infinity. This means that for every i, the set has a finite value, but as the number of i increases toward infinity, the value of the set goes toward infinity.

An actual infinity is an infinity at all points of i. When i=1 the set is infinity, when i=100 the set is infinity.

[Satarack]

@TheCopaceticMan As a result, actual infinities are indistinguishable. We can't tell the difference between one actual infinity and another. With potential infinities we can; because we can see difference in the rate at which they tend toward infinity, and can describe it. But this is not possible with an actual infinity since it's value is infinity everywhere.

So when we encounter infinity - infinity = ? we can't tell if the difference is zero, less than zero, or greater than zero.

What about the actual infinite distance of space?

If that does not exist, then what do the edges look like?

[ASeventhSign]

@marveymarker

The Universe (including space-time), is generally accepted to have had a beginning. It has been expanding ever since this beginning. Therefore your "distance of space" would indeed be finite.

The edges are purple.

[ChristusVlCTOR]

@marveymarker Space, although finite, has no edges... this can be dificult to imagine but try and think of a line ---- the line is finite, and it has a begining and an end, but if you take the line and bend it back on itself, it becomes a circle O, it is the same amount of space, but now without ends. Our Universe exists in the same way, only in three dimensions. So whatever direction you travel in, you will eventually end up back where you began. Finte, without edges.

[marveymarker]

@ChristusVlCTOR from the videos I have watched like "Lawrence Kraus" they suggest that the evidence is that the universe is flat, open and infinite.

[ChristusVlCTOR]

@marveymarker I'm not sure where you got that from, but it is my understanding that because of the sheer gravity of Space, that the further you go, it eventually begins to curve back on itself.

[xdairybastardx]

Why do these people have such a difficult time understanding what he's saying? I understood what he said instantly the first time I heard it. Is that just me? :/

[drcraigvideos]

@xdairybastardx Nope. Usually atheists (especially youtube atheists) already have their minds made up even BEFORE they hear the Kalam Cosmological argument. In reply, they'll say the most incredibly idiotic things, from "nothing can do something" to "what caused God then". Trust me, I've heard them all.

[MrRyans777]

@drcraigvideos It's also because of their ego and their pride lol
