    Theory
In summary, there are many theories about the origin of the universe, but the Big Bang cosmology is the most widely accepted one at this point.

Is there any other theory except for the big bang which explains the origin of the universe satisfactorily and which has not been ruled out as yet?

Big Bang cosmology doesn't currently explain the origin of the universe --- it mostly addresses how the universe expanded subsequently.

i thought that the big bang continues by the reunion of black holes in one big black hole that would explode when reaching the critical mass starting the universe again.

modern scientists can't explain the perfect tuning of the universal constants that allow the starts to last that much or that permit life to exist. So they have three choices: accept the existence of a creator that sets this constants or accept the existence of more than one universe with different universal constants

anyhow understanding the creation of the universe is something beyond our capacities since we can even really understand something as common as "infinite"

myself i vow not to think about these things anymore, last time i almost got totally nuts

There are some theories that speculate whether a Big Bang could be the result of a previous Big Crunch, but we really have no idea whether this is true. The current evidence suggests that our universe will not recollapse into a Big Crunch, but that doesn't say whether there has been an earlier one.

No, that's hardly true.

People don't even agree on whether fine-tuning is something that needs to be explained, if life was simply an accident. We don't even know whether there really is any "fine-tuning for life" -- there may be fine-tuning for our kind of life, but who knows what kind of life might arise in a very different kind of universe? And if our universe is so "fine-tuned for life", then why is over 99.99999% of it uninhabitable to us?

For that matter, the fine-tuning argument only makes sense if you assume that the constants could have taken on other values; it's possible that the laws of physics only allow certain values. And even if many values are allowed, you still don't have to resort to "many universes"; it could be that the constants in our universe are, while not inevitable, at least probable.

If you hunt through the talkorigins.org site, you can find numerous discussions of this topic. The first three relevant links that Google gives me are:

http://www.talkorigins.org/indexcc/CI/CI301.html
http://www.talkorigins.org/origins/postmonth/jun98.html
http://www.talkorigins.org/faqs/cosmo.html

Anyway, alternative that fine-tuning can be construed as evidence for a creator is flawed; see, for instance, this probabilistic analysis:

http://quasar.as.utexas.edu/anthropic.html

By the way, I didn't see a third choice among the possibilities you listed.

Mathematicians can think and reason about the nature of infinity, and physicists can think and reason about the nature of the origin of the universe. We don't know whether any of our ideas are right, but it's not literally inconceivable.
 

1. How does the alternative theory of the origin of the universe differ from the Big Bang theory?

The alternative theory suggests that the universe has always existed in some form, and that there was no single event that caused its creation. This is in contrast to the Big Bang theory, which proposes that the universe began as a singularity and expanded rapidly from that point.

2. What evidence supports the alternative theory of the origin of the universe?

Some evidence for the alternative theory includes the observation that the universe appears to be spatially infinite and has no edge or center. Additionally, the theory is consistent with the laws of thermodynamics, which state that energy cannot be created or destroyed but can only change form.

3. Are there any competing alternative theories to the origin of the universe?

Yes, there are several alternative theories that propose different explanations for the origin of the universe. Some suggest that the universe is constantly expanding and contracting in a cyclical pattern, while others propose a multiverse where multiple universes exist simultaneously.

4. How does the alternative theory explain the formation of galaxies and other celestial bodies?

The alternative theory suggests that galaxies and other celestial bodies were formed through natural processes such as gravity, rather than a single explosive event like the Big Bang. Over time, these bodies formed and evolved through interactions with each other.

5. Can the alternative theory be tested and proven?

Currently, the alternative theory cannot be definitively proven or disproven. However, ongoing research and advancements in technology may provide more evidence to support or refute this theory in the future.
