I going to not answer this just yet, because I suspect you are using two different meanings of faith, but trying to make a conclusion as if they were not different. So... hold that thought.
Although, while we’re holdng this thought, let’s ponder whether you KNOW that you are using two different meanings, or whether you really and truly do not know the difference. Either way, hold that thought.
Are you both saying you believe we have had all those eons and eons of time to "observe" ALL of the above expanding universe? Empirical tests?
I would not use the word “believe” because it is imprecise. Indeed, some people use it to mean that that accept a conclusion on no evidence. And other people use the SAME WORD to mean that they accept a conclusion based on substantial evidence, but it’s a conditional acceptance in case new evidence shows up. Still other people use the word to mean they think they are right, but their memory is faulty and they don’t want to claim perfection.
So you can see how fraught it is to use the word “believe” when precision is needed and perfectly clear alternatives are available.
So here’s what I conclude: The evidence that the universe is billions of years old has a pretty high level of consilience, wherein multiple different ways of measuring all come up with the same answer. And no ways of measuring come up with a fantastically different answer. Therefore, it becomes relatively confident to conclude that the consilient evidence points to a factual answer. It’s provisional, at this point, but I can say with near certainty that no BETTER conclusion is possible.
Moreover, the usefulness of the science that goes into those observations and measurements has so many other applications that make reliable salient predictions for my life that it inspires further confidence.
Religion, as has been noted, has never made a useful prediction, ever.
It's NOT true observation - It's not actually seeing the process in work.
A lot of people who don’t follow science say that if you didn’t see the tree fall, then it made no noise.
But, honestly, do you really conclude that?
Observation of other falling objects, including trees today suggest a strong confidence in the noise of the one that fell during the dinosaurs and then got buried in a river and later fossilized, only to become a stone exhibit in a national park in New Mexio.
Moreover, observation that any moving object can have pressure waves - and hence sound waves - measured from it adds voice to the evidence. And not only that but other evidence of sound can be found as well.
So do you REALLY “believe” that the tree that fell a million years ago made no noise because no one was there to make a “true observation”?
It was based on an interpretation of the redshift/ hubble law (disputed among scientists) i.e. there are flaws.
As far as I can tell, the dispute seems to be over
how fast the universe is expanding, not
whether the universe is expanding. Are you sure you know your science here? Are you sure you know it well enough to make this claim? Knowing that the dispute is about 5%-10% difference, not whether it is altogether wrong?
You are saying that you don’t know whether Usain Bolt made a world record because the two timers were off by a thousandth of a second, despite him breaking the world record by a tenth of a second.
Science is so fun, Learner, you should dive into it and Learner more.
sorry a bit tired to answer individually, it was way past my bed-time.
I hope you were up late reading at ScienceNews.org and learning about neat things like
Debate over the universe’s expansion rate may unravel physics. Is it a crisis?
Where you can read about how the questions about the hubble constant do not dispute the Big Bang, but rather whether there are more particles in the universe than we can see so far (perhaps because they do not emit light, for example)
Are you both telling me, you DO have faith?
I have faith that my seond glass of wine will be as tasty as my first.
Although even that is imprecise, isn’t it, since I’m using the same glass and just refilling it.
I only every have one glass of wine a night, I believe.
