Is the Universe a result of an accident?

The Universe just is. No one accidentally knocked a star into another and said "Hyuk! Did I do that....?"

Most likely, Given enough time, you can come up with just about anything. I know there is this thing going around about how if gravity was x % weaker or stronger, if electromagnetism was x% weaker or stronger, we couldn't exist and that given the odds of all the factors there must be intelligence behind it. What they are doing to takes the end result and saying it is the ONLY way you can get life and the universe. That is not true, those are the the things we need for OUR universe and there may be other combinations that would result in stable universe. Even if it were true that this is the ONLY combination that would support life that doesn't mean it was planned.

Edited could to couldn't sorry

That depends on how you look at it.. I (not so) recently saw a documentary on how big the universe is, how it started and how it will end, and basically, there has been a completely different universe before "our" current one. It's not like there was nothing, then *poof* everything was "there". That's not how it went. Instead, there was a universe with differnt materials, different physics, different everything. Then, a so-called "phase transition" will occur. This happens when "A collapse of the universe will happen if a bubble forms in the universe where the Higgs particle-associated Higgs-field will reach a different value than the rest of the universe." - Phys.org. This means that another phase transition is possible at any point. It may even happen 30 seconds from now. Everything will dissapear, and a new universe will be created. So you could say it's meant to be, you could say it never should've happened, you could say it was just a coincidence.

Who (What) posted principals of physics? Did they invent themselves? Did gravitation, electromagnetism, weak interaction and strong interaction pop out from nowhere and said "Look! So many motherless particles! Don't leave them useless! Let's arrange a kindergarten for them! Hey, don't forget to call the Spin! Rock'n'roll brothers!"

No.

In my personal opinion, the universe is an organism of transcendent love and power. I don't know how it came into being or even if it ever did.

But virtually every cosmological model has the universe as having always existed. There never was a "before". So there never was an "accident". The universe is what it is.

I believe God created the universe. On purpose. If you want scientific proof, I can't give it to you. I wasn't there to observe, and neither (as far as I know) were any of the scientists who theorize about it.

I'd say a coincidence more than an accident, but it works too. You should ask yourself too... "What if?"
