Mind-Boggling Questions

[Simsim]

Here's some mind-boggling questions I've been pondering for a few years now.
Why is life the way it is?
What was outside the Big Bang?
Could life have happened in a way we cannot perceive? (Like having 67 dimensions and totally different laws of physics, etc)

These questions aren't thoroughly detailed but...meh, I'm only 16...

Hi Hetch, I will give answers within the scope of my knowledge and, of course, my linguistic abilities:

Why is life the way it is?

because if it was anything other, the question would be the same This question would be posed at all cases.

OK... Our life is a carbon-based life, because carbon is tetravalent so it can form 4 bonds and long molecular chains which are the main stay of life.
Also carbon is relatively abundant in the universe, because physical laws allow it to be abundant.
A marked counterpart of the carbon-based life is the silicon-based life, because a silicon atom resemble that of carbon as it have 4 electrons in the outer level. But, of course, the silicon-based life is a hypothetical model that we haven't detect, and we mainly will not. I think scientists one day will produce this hypothetical form in their laboratories, but this will happen after preparing the complicated forms of our lives.

What was outside the Big Bang?

Nothing !

There is no even space outside there. You may ask in which thing had the universe expanded?
The expansion is not into a "place" outside the universe, but it is an expansion inside the universe. All the matter is that distances increase within the universe. Distance is a physical quantity like time and mass. If you look at distance as physical quantity involved in the universe you will not need to suppose "another distance" outside the universe to permit the universe to expand into.

But the concept of the "nothing" differs from classical physics to general relativity to quantum fields. I think it needs a separate particular topic.

Could life have happened in a way we cannot perceive? (Like having 67 dimensions and totally different laws of physics, etc)

Einstein asked if God had a choice in creating the universe. He meant to ask if this set of physical laws was inevitable and the universe couldn't be made and governed according to other sets.

Of course this is a hard question. I think Einstein thought that this is the only set of laws which the universe could have. But modern science predicts infinite numbers of universes with in infinite number of sets of physical laws, and then even the styles of lives or universes which you think they are improbable or impossible are, if fact, inevitable.

Multiverses have many visions and many perspectives. One of them that the universe must take every possible path, but we are concerned only with our path which we can observe because the other paths are not "realities" with respect to us.
