That was the guy I was talking about that compeltely debunked Harun yahia.
He's been around for a while tho ...

Going to have to jump in here and say that his lecture on infinity was wrong. Infinity is tricky, though, and many of its subtleties can become very confusing.
Error #1He says that God cannot be infinite if the universe is not part of him, but that is not at all true, and here is an easy analogy to understand:
If a set of numbers, x, includes every number greater than zero, then x is clearly an infinite set.
Equally clearly, -1 is not a part of x.
What is true, though, is saying infinity + 1 is not really possible, and the following is also true:
y = x +1
limit [x->oo] y = oo
and
limit [x->oo] x/y = 1
...which would appear to say that x = y... BUT!...
limit [x->oo] x-y
= limit [x->oo] x - (x + 1)
= limit [x->oo] x - x - 1
= limit [x->oo] - 1
= - 1
So while the statement is true in some respects, it is certainly not always true. What is true, though, and what I believe he is attempting to communicate is that there is no number that is larger than infinity. Also similar in concept is that you cannot add/subtract a finite number to infinity or multiply/divide infinity by a finite number and produce a finite number; it is still infinite.
Error #2He says that there are no more milliseconds than seconds in an infinite amount of time, which is also untrue.
x = number of seconds in a specified time duration, t, which is in seconds
y = number of milliseconds in a specified time duration, t, which is in seconds
x = t / (1 second)
y = 1000 * x
With these assumptions, x - y, according to him, is 0, but it is not. Similarly, x/y should be 1, but it is not. In order to solve x-y or x/y, which are indeterminate forms, you must make use of L`Hopital's rule, which is often very easy to do:
indeterminate form oo - oo:
limit [t->oo] x - y
= limit [t->oo] x - (1000 * x)
= limit [t->oo] -999 * x
= -oo
indeterminate form oo / oo:
limit [t->oo] x / y
= limit [t->oo] x / (1000 * x)
= limit [t->oo] 1/1,000Â * (x/x)
= 1/1,000
Is this boy claiming to be a Math PhD?Â
 This is Calculus 2...Â
Anyways, to correct the second analogy, the problem with it is that there is a formula that directly and indisputably converts seconds into milliseconds, and it is not at a 1:1 ratio. A more accurate analogy that I suppose communicates the same idea is something such as, "There are more supernovas in an infinite amount of time than there are hairs on the heads of all humans."
