i was watching the history channel last night and they were having on show on how the earth was made and showing what it looked like in certain points in time like for example 630 million years ago the earth was iced over. then 550 million years the earth was crusty as a volcanoe. just examples but it went like that. how do they know they weren't there.
They create theories and do their best to test them, but I know what you're saying. I always take those shows with a big grain of salt, and it bothers me to know that a lot of people probably don't. They don't consider what a huge difference even minor discrepancies can make in their reenactments. You're presented with these scenarios as though they are 100% factual and they just aren't.
They'll look at the layers of soil in the ground, or the compositions of rocks found at certain levels or the layers of ice at the poles and look for evidence of sudden changes in them and whatnot. They obviously don't know for certain, but you're venturing into Schroedinger's Cat levels when you start saying 'they don't know because they weren't there'.
yeah dude minor fuck ups, or major in this case. they said life starts in the oceans and shit and then in another show on the same channel. they claimed nobody knows yet how and where life formed, if could of originated in space, could of started on our planet and loads of other things. i know about the soil, but damn dude i dont really think they can go back billions of years think they are absoloutely spot on, they're methods could be in error, just as the ideas of people of the past were.
Isn't it important to be spot on, though? And then to just omit those details that you have no choice but to guess at? I know it doesn't make for the best TV, but the mind tends to just accept what it is seeing when people speak with authority on a subject, I think. When I think of an atom, I still get that fifties image of electrons spinning around a sphere in my head.
The moon isnt round either.. In fact its not even there.. You have just been told its there and think its there but its really not.. Its all a figment of your imagination. lol.. Like I would know...
i know the moon is there b ecause i can see it. we can study the moon as it is now, and even then are knowledge about it can be off because our methods aren't always going to be perfect. and our methods not being perfect combined with billions of years ago, wer sure as fuck cant know what the fuck went on back then. just cause scientists on the history or discovery channel talk all this shit like its true an dfact, dosen't mean it is. all their "knowledge" could e nd up to be bullshit, just like what happened in the past.
They tell by the rock layers. Like for example, they can tell from all the limestone in the midwest that we were under an ocean a long time ago. Also the whole pangea thing, not only do the shore lines of south america and africa fit perfectly, but the mountain ranges of america and europe are of the same substances, so you can tell that they were once connected. Also they can tell from the tectonic plates. We know the direction that the move in now, such as the indian plate moves ito the asian plate and thats how the Mountains were formed. Since we know which direction the plates move in, we just retrace it all and go backwards. So most plates move a few centimeters per year, so to find out what it looked like a few thousand years ago, we just diagram it to move the plates a few thousand centimeters away from where they are. Its a very complex thing. From using data that we know, we can find out what we dont exactly 'know' such as what it looked like in the past, and what it could look like in the future.
Im no geologist, I dont really know how it goes, but theres probably all this scienctific calculations and what not. Theres alot that comes into factor, like weather the plates are oceanic, continetal, and what not, and all of the volcanoes. Like the places where theres lots of volcanic action is where alot of the plates are moving. Same with earthquakes. Theres probably lots of patterns, but like I said I have no clue.
The earth has undergone what is known as a 'changing period' numerous times in the past, by which the earth reverts back to its original state through phenomena such as crustal movement, volcanoes, tidal waves, etc., and it repeats this cycle at an interval. All the creatures become extinct and all the civilizations disappear instantly. Nobody knows how long the earth has been existing through this process, but the various factors like speed of crustal movement, etc. are influenced by the activities of what is existing on earth at the moment. So in order to know specifically about those factors we need to look at the geological records and we can make a calculation, but the problem is that there's no record of what happened back then. I heard that there will be a changing period in the 21st century. The page linked here has more info if you're interested.. What is the changing period ?
so what you are saying is, the earth goes through repetitive stages over and over again throughout time, and each time different species arise and influence how the earth changes by its actions effecting crust movements and shit. interesting could be true, but maybe not.
