That's a good question about annular eclipses, but I'm certain Tom has figured this one out. He's the greatest FE mind of our generation. Tom?
Yikes! Really? That's the best you guys have? Wow!
Anyway - Tom believes that light travels in straight lines - but that the "laws of perspective" (which derive solely from the "straight lines" thing) are broken. I don't know how he can keep this straight in his head - and he gave up posting to my thread on this important subject...but that's his problem.
The point being that if he can simultaneously admit and deny some rather fundamental fact like that, his "explanations" for things like eclipses cannot be trusted either.
Bottom line here is that if light DOES travel in straight lines then there are no sunsets - and if light DOESN'T travel in straight lines then there are no eclipses...well, not without magical fairies who can bend light on demand to order to make it do whatever the heck Tom wants it to do.
Nearly every day I find another phenomenon that nobody here can explain. Tom typically attempts one or two answers then disappears off the thread once he's proven wrong.
Just look at the dozen or so threads I've started in the "Debates" forum...read the sequence of posts from me and from Tom - not a single one of them ended up with an FE "win".
