The Planets

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.
 
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.
 
It's a programme not a program! :mad:
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.

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.
 
I’ve only watched two episodes so far but things like how Mars was formed, it definitely had an atmosphere like ours, how certain parts of the landscape were formed. It’s all fascinating but it is all best guess.
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 confrontational😁

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.
