This, gentlemen and ladies, is the Earth.
It's big, it's covered in people and water, and it's about 5 billion years old... ish.
These are some facts which are more or less indisputable. Here's another one:
The earth's crust is made up of plates. These smack together and make earthquakes, volcanoes etc.
Now a geologist or a geophysicist could do a more thorough job of describing geothermal activity but none of them could do it quite so controversially as proponents of the "Expanding Earth Theory".
If you've not heard of this before, don't be surprised. There's a lot of blurb on the wiki page. The biggest modern day supporter of this.... 'theory' is some yank called Neal Adams who, despite being a comic book artist, has decided he's more knowledgeable than every notable physicist, geologist, geographer, and sane-person in the history of everything ever.
The idea is that Earth has been, and is still, expanding outwards due to some... bizarre and inexplicable process of matter creation happening inside its juicy innards. Now... I won't go into the physics here but suffice to say the theory is (what's technically called) "crap". Anyway, this expansion explains everything that plate tectonics already explains fine, but in a more roundabout and convoluted way. Hooray! And clearly, this is all a big conspiracy that all the world's governments are in involved in because.... they make a lot of money from this sort of thing?
I'm sure there are plenty of scientific and psychological reasons why people feel it necessary to hold totally unreasonable, unsupported and plainly idiotic opinions when there's overwhelming evidence to the contrary. This goes out to all you "the moon landing is fake" people; or all you 9/11 conspiracy theorists- WHY do you feel it necessary to hold desperately onto your inadequately supported ideals in the face of people that actually know what they're talking about?
I've spent too long on conspiracy theorist articles and websites to hold too much anger anymore. I've moved on to despair and pity.
