It doesn't make sense to say that something changes, so change must be an illusion, and nothing ever actually changes. So palmenides was a bit out on a limb. He felt that there were good logical reasons for saying that nothing ever changes. Everything is always there. Is just one thing which is unchanging. And the way i think about that is when we talk about einstein and space time. We think time is linea but actuallyf you talk to some kind of time oriented physicists,. they might tell you, no, you may see this whole thing, and time is e spots are within it.
