why is it so big ? why is there speed of light law ? is it so big on purpose to keep us wondering but never be able to contact any intelligent civilizations out there ?

I dont think worm holes and wrap speeds are possible...i think speed of light law there for a reason. Whats your thoughts on this?

Nothing is "for a reason", it's just the way things work. The universe does not have a purpose to make us wonder anything -- it's just the way it is.

Mhm, and an interesting thing we've found is that if any of the universal constants were different in value from what they are now ie. the gravitational constant, speed of light, permissivity of free space, etc. the universe would not be able to function as it does now, which gives a sense of unity to what exists now.

There are yet no observable reasons for why it is so big though..

Well, from the research I've done.
The universe is or was expanding, and eventually begins to contract.
Like everything in life, there is an opposite. Not everyone can comprehend the definition of dark, without ever being in light and vice-versa.

As for the universe, it expandes to a certain point, this takes an amount of time uncomprehensible by us, by anyone I'd imagine. This is also due to the definition of time itself, being relative.
Once the universe has come to it's point of expantion, it begins to contract. And yes, once fully contracted... nothing will exist, for like the smallest "time" imaginable. Then it will start to expand again.
Now, I'm not yet sure if this has ever occured, because I'm quite sure if it did, some civilizations who might be billions of years old, would of found a way around this inevitable cease of existence.

As for your questions:
why is it so big?; answered above.
why is there speed of light law?; Well this exist because it's a fact. There is a speed that light travels by, somewhat measurable in science. Wich some believe is the fastest speed.
is it so big on purpose to keep us wondering but never be able to contact any intelligent civilizations out there?; To keep us wondering, yes and no. Depends on the civilizations amount of understanding. It's to allow different beings to be able to prosper on their own, without outside force. (to some extent...) Example if aliens lived on the moon, it would've had a impact on us both.
I dont think worm holes and wrap speeds are possible...?; I recently researched about teleportation, worm holes, tunnels etc. The amount of data out there for this to be possible is obscene. But achieving it is even more! Some scientists/reseachers/doctors/etc. have been able to achieve it, but at a very minuscule event.
To be more clear, anything you can imagine as being some sort of magic or impossibility, is a reality somewhere, due to technological advances and so forth.

e - forgot to bold one part.

So that my penis has room to be contained within it.

Amazing post, thanks

They're doing tests right now of an actual warp engine. It works by contacting space ahead of you and lengthening it behind, putting you in a sort of warp bubble that doesn't move.

The theory all seem to check out, so they're doing a proof of concept by building a very small warp engine that will expand and compact something the length of a, table leg

This is very informative, but the big crunch and the reasoning for the size of the universe are just speculation. Science really doesn't know.

Given the universe's acceleration of expansion, the big crunch haven't really been believed in by most scientists in nearly 20 years. The prevalent theory right now is the universe will expand until all the solar systems go so far from each other, gravity doesn't keep them into neat galaxies, then planets escape their suns gravity, so on until all that's left after the last stars go supernova is some background radiation.

There is no known "why" or "reason" regarding the nature of the universe. It just is. The universe could be infinite or finite in size, we do not know. we can only observe so far.
