[00:02] to propose a heliocentric model it was arist starus who did this in 300 BC but his idea wasn't accepted the other Greeks um dismissed him for good mathematical reasons they said that it doesn't make sense for the earth to go
[00:15] around the sun because if the Earth would gr on a sun the position of the as you go from one side of the Sun to the other and we don't see that so if in three-dimensional space and you picture yourself as an observer staring
[00:29] at the stars and you move around through that three-dimensional space then the apparent relative position of those Stars shifts around as you move we call where if you're on a car in the highway and you look out all of the nearby trees
[00:45] the background mountains so when aristarchus says Hey guys maybe the Earth is going around the Sun all of his fellow Greeks are like well if that was true and you've got this Earth Sun System sitting among a bunch of stars
[00:59] then for us The Observers sitting here on the planet Earth as we move around through space from Winter to Spring to Summer and it's going to be quite a bit evidently the sun is supposed to be quite far away from the earth then
[01:12] because of this Parallax we should see a change in the pattern of the Stars the bit more than the background stars and the overall shape of the constellations should slowly drift through the seasons but that's not what we see the
[01:25] constellations seem to be the same shape between the summer and the winter and that would only be possible if the stars were much much much further away than we currently think they are so arus if you were to accept your model we must make
[01:37] times bigger therefore we were not going to we're going to dismiss your theory it the math right you don't necessarily get the math right you don't necessarily get to the truth
