I was referring to over 30% of Americans (YEC) who believe the Earth/universe is only 6-8,000 years old when the scientific theory suggests 4.5bn years for the earth and 13.8bn years for the universe.

Hell no! I watch SciManDan weekly. ðŸ˜Are you a flat earther by any chance?

It's all fascinating stuff. A lot of Astro physics scientists are right in a lot of respects, else how do the space missions to other planets turn out right, but I see where Kellfire is coming from, because a number of these scientists then go off on theories about black holes, multiple universes etc, which are exactly that- theories.
Facts, by definition, is what is provable. That is what he is saying, and anything else is some sort of theory-Some theories can be facts ( Pythagoras), because they are proveable, but astronomical theories tend to be the vernacular understanding of theory, I.e intelligent guesses.
BTW, the most wonderful Astro physics program I saw was about the Saturn mission where the spacecraft was plunged into Saturn at the end of its "life".
During the programme there was a photo shown where the shot was taken from the other side of Saturn looking back towards Earth. And our planet is no more than a small white dot in black space.
I've kept that sequence which I look at from time to time to remind me how insignificant we are.

Where I come from (NZ), either/both spellings are recognised/acceptable, so not an 'Americanisation' I'd consider objecting to - unlike the likes of 'color' etc.It's a programme not a program!
I bet the Yanks don't have a clue about the word 'outwith' though! I'd never seen/heard that until I worked in Edinburgh! It's rare to see it outwith Scotland
- mainly in legal docs.

Indeed But so was The General Theory of Relativity - for around 100 years! But a prediction (about Mercury 'emerging' from behind the Sun). And confirming (or not) that 'best guess' is why so much is being spent on space exploration - particularly to Mars!

It seems to me that, in the bold bit, you you are describing 'theorems', not 'theories'! Subtle, but important difference!

Yes, agreed they are different,but , as I read the definitions, all theorems are theories( which are proveable), but not all theories are theorems.
But I wouldn't argue the case with a professor of semantics😀

Wrong!
The spelling may be similar - derived from the same Latin/Greek origins - but that doesn't mean squiddly about the actual meaning!
There ends today's lesson in English/Physics/Maths. I'm off to apply some of the theorems (Ballistics/Gravity) while walking around a (somewhat) manicured park!

I have gone by the definitions of each,according to Cambridge English dictionary . Maybe we read them differently, but no big deal😀
Hope you hit the spheres in the right direction

Indeed, I note the difference! Theorem's meaning states '....can be shown to be true...', while Theory does only mentions '...suggested to explain a fact or event' and '...an opinion or explanation'!
I hope you read, and don't interpret, The Rules of Golf better than your reading of those 2 distinctly different meanings!

I suggest we're on the same page , but you're not seeing it. Read my post earlier.
I said all theorems are theories which are proveable. Iow all theorems are theories ( or opinions or explanations) which are true.
But not all theories are theorems ( because some theories are not proveable as true, ( but may become so, who knows.?) )
As for the rules of golf, gimme some slack .My game is bad enough to need a little interpretational help 😀
Not all replying posts are confrontationalðŸ˜

I see/saw 'where you are/were coming from', but simply, respectfully, disagree - with both highlighted statements!
Here's a good set of explanations why! https://www.quora.com/When-does-a-theory-become-a-theorem

Mrs just put this on and ive never been so bored watching TV.
I love the planets and solar system science but him as a presenter made me want to go and stick wasps up my backside for entertainment he was so dull is his delivery.
