Further, they poopoo science as just "opinions".
Next, enter the PC thing that everyone's opinions are equal, therefore whatever I think is as valid as what Einstein thought .....

Science cares about what's true, not protecting what there is insufficient evidence for.

Being willing to admit you were wrong to believe something is not a bad thing.
It's a good thing.

Very well said indeed............

i got my own theories, but cant really explain them and the math is beyond anything possible yet, anyway, the earth will die before anything happens in this universe, when the sun reaches its life span, it will turn into a red giant, meaning it will span to the the orbit of mars most likely, instead of 1 million miles in diameter, it could go to 300mil or greater, but that wont be for another 4.5 billion years, the real problem is- will guitar center be around for another 20 years?- LOL

Well then, you should avoid each and every scientific theory, past, present and future.

No scientific theory provides a final answer. A scientific theory is simply the best explanation of all currently known relevant empirical facts concerning the topic area. Thus, each scientific theory is tentative and subject to falsification, in whole or in part, based on newly acquired evidence. In addition, scientific theories make predictions of certain (as of yet) unobserved phenomena. As those predictions are later observed or encountered, the confidence in the theory is increased.

It's a matter of probability, not certainty.

You are forgetting use of the adjective "scientific", as in "scientific theory".

Please describe, in your own words, what is meant by the term "scientific theory".

Truth is truth and is verifiable. Hard to get to sometimes but that is the goal. 'Scientific Theory' is a made up term to give science some wiggle room. That is fine in my opinion. You are going down the road in pursuit of the prove out. Until you hit proof you are still in theory. Much can be learned along the way but let's not mince words. A 'Theory' will always be just that. 'Scientific Theory" does not get a free pass because it's 'Scientific'. You either prove your thought beyond doubt or it continues to be your best opinion on the matter. Don't make me give examples.

I myself am dying to hear what you call examples.

And by the way truth and facts are not even close to being analogous.........

Scientific theory requires proof.

Really? By the way, I mentioned truth in my last post but I did not mention facts. Facts are a stepping stone towards truth. All for it. You want examples? We have an historical record of misfires. That is how we move along. Who or what are you defending?

A scientific theory is a well-substantiated explanation of some aspect of the natural world
that is acquired through the scientific method and repeatedly tested and confirmed
through observation and experimentation.
Scientific theories are the most reliable, rigorous, and comprehensive form of scientific knowledge. wiki

Also truth is determined by history. What was true 200 years ago may not be true today.
That which is considered true today may not be true in 200 years.

Yes it does. But it only pertains to specifics. Only a part of the big picture. Each piece of the puzzle helps. No one has finished the complete puzzle.

We have all kinds of science, all kinds of truths. I wouldn't get too worked up over either as mankind has a habit of messing both up one way or another.

Anyway,

Quote:

Does anyone have any scientific ideas or theories as to how the universe and the earth and the world could have come into existence? I have no idea. It's beyond me.

We have theories, but no proof. We have beliefs, but too many to name, too many to merge into one concrete idea, too many to make a common consensus.

We are here. Make the best of it.

That was well said. I don't think we are in disagreement.

Sorry. We only have words here. I really don't mean to offend. So my apologies are in order.

I missed this post. (sorry, I seem to be making enemies!). I stand by truth. It is consistent. It does not falter. In speaking of our existence we all seem to reach out for answers. That is our curiosity. Considered truth doesn't count. What is real remains today and 200 years from now. I guess it is up to us to discover it.
