As long as nobody gets hurt, "anything goes" should be the standard. Regarding sex: People should be educated so they use condoms & co, but the church even tries to suppress sexual education in school.

So if time didn't exist before the Big-Bang, then it would be correct to say the universe had a beginning? 

I had sex ed in my school and they showed how to apply condoms and everything... And my school is catholic.

Yes, the Big Bang.

3. Ah... that makes no sense, mathematically. Firstly, there *are* infinite infinitys of strictly different sizes (look up: cardinalities. One common example is that the set of all real numbers is strictly larger than the set of natural numbers. Generally, if you take an infinite set, the set of all subsets is strictly greater, which is how we know there to be infinite *sizes* of infinity.) Though that certainly isn’t necessary to explain an expanding universe of infinite size - notice, in this context, expanding simply means that any two objects, in average, get farther and farther apart. Look up hilbert’s hotel for that.

I have no education on the physics involved in the big bang theory, so I won’t try to explain something about it. However, something you generally have to understand is that if you can come up with a question, physicians have certainly thought about it as well. And there most likely exists a perfectly coherent answer to those questions, it’s just unlikely that you could *understand* it. People spend years upon years on physical concepts before attempting to read any contempory papers. The accumulated knowledge is just too great for anything to be accessible to a general audience, these days, sadly.

And there certainly are things that we do not know, there will always be things that we cannot know. But that in no way invalidates any of the work that scientists have created on what we CAN know.

Pretty much - but this is a hotly debated area of physics.  The opinions have probably changed since I studied!

The basic principle is that time only happens because something physical happens.  So an atomic clock atom decays, or entropy (randomness) increases.  If there is no energy or matter, then nothing happens, so time doesn’t exist.

don’t forget that the rate that time passes varies with relative speeds, etc.  So at least that much can be measured experimentally.  I never fully understood what people were saying, so this is my understanding :)

IMO The Catholic Church is worse. Especially considering they have the power to hide most of their corruption and scandalous activities.

And every once in a while, someone comes in who has missed the entire conversation. Bravo...

No, because we don't know. 

The universe could have existed forever and has been contracting and expanding to and from a singularity forever. We would likely never know because the big bang destroys any evidence we can detect of what was before by virtue of the event, all science knows so far is that it happened.

Good correction.  :).  There are a number of theories.  Personally I prefer the “this is the only Big Bang”, but I am in noooooooooo way qualified to say that :)
