I did the normal science subject at school
Then dis Maths Physics and Chemistry at 'A' Level
then Chemistry at University - including a high level course of Astrochemistry
and after that helped several people doing Open University Science courses
I knew a lot about how things where detected and measured
SO I thought I kinda knew about science and some space stuff
Then I went of a holiday where I shared a room with someone random. Turned out to be an older bloke who had spent most of his life making high precision tools and equipment
He asked me how far away the nearest star was to Earth
and what about the others
OK - I knew that
OK - he said - how do they know
OK - I knew that
he pounced
HOW do they know - and what it the possible error
It is all based on angles measured from Earth (this is the 1990s - it is more certain nowadays - but no absolute because that is impossible)
and the angles HAVE to have an error
so how far is it
a very quick estimate says it is HUGE
which kinda shows that people know some bits about science - and trust scientists - and the people who check the scientists - that the rest is accurate
i.e. they believe it
so - How deep is the deepest part of the Ocean???
and where is it??
how do you know??
you trust (OK if there is an Ocean Scientist on here with a depth guage - pick something else!!! - how high is Everest??)
you cannot know everything
youhave to look at how many people have looked at this - who has checked it - do the assembled scientific community agree having checked etc etc)
so you believe - because you can see that a huge number of people who can be trusted to check this stuff agee that this is correct
now go back
and imagine that you live on La Palma and that volcano does what it is doing
and you witch doctor says it is because the Gods are are angry because you are not giving enough in sacrifice
(look up
Jesse Duplantis and his view that if you give more MONEY Jesus will return)
and imagine that this is your one and only source of trustworthy information
what can you think
I mean - if Brian Cox says something my wife is seriously inclined to believe him - dunno why - but I don;t think it his Ph.D!!!
Anyway - what I mean is (finally) we cannot know everything we get thrown at us nowadays
we can only try to look at who is saying stuff
and who is repeating this having - hopefully - checked it
and deciding that this is trustworthy - and this is not
so - going back again - and my priest says this is OK - and I should do it
hmmmm - you see where I am going
so
in ancient times
the chief or witch doctor say THIS IS TRUE then what other choice do you have - if is makes sense - it must be true
nowadays - we have a far too massive amount of information available to us
for example - there is evidence tha ther is a teapot floating in space between the Earth and the Sun - either you know where this goes - or Google it (orr Dudkduckgo it if you are likeme) but ther is evidence
but the volume is huge and a lot of it is rubbish
so we end up with a lot of people getting overwhelmed and going back to trusting the sources they know
which could be Facebook, or Twitter, or Fox News - or their local priest
I mean the Pope seems like a good person
bt this is just how people work - we cannot deal with everything so we find someone to trust
it may be a priest or shamen or Brian Cox
it just depends on what information and education and facts we have available to allow us to make a judgement on who to trust
and how actually trustworthy that person happens to be
if the priest ( of whatever type) wins - sometimes that is good
sometime very not
Yea gods I woffle sometime when I have had a few glasses of wine
