But photons aren't massless. It has been proven.
Large bodies bend the light behind them. Looking at the edge of the sun we can see stars that should be obscured.

All you're demonstrating now is your own ignorance of phyics.
Photons have no mass. They have energy, which is equivalent to mass (special relativity) and they follow straight paths in curved space-time (general relativity). That's why their paths are curved.

It's cool that you're interested in this sort of thing, real a few decent books on the subject and you'll see where youre misconceptions come from.

I've read many books on this. I just disagree with a lot of the assumptions modern physics has made.
I believe photons have mass. I don't believe in real values of zero or infinity for anything. Even if it's so tiny as to be negligible, everything has mass and energy. I don't believe space-time is curved, but rather constantly expanding, giving events and particles the appearance of having traveled along a curved path.

Meh. You want to argure with Einstein?
I'd be delighted to see your paper.

Certainly. I published a small book called The False Tesseract last year.
You probably won't find it in major bookstores. It's 50 pages and small enough to avoid acquiring an ISBN. A library might be able to get it for you.
