Of course, same as anyone's. But evidence-based (i.e. informed) opinions outweigh those that are not evidence-based.
This is a fact: objects, unless acted upon by another force, are pulled toward the earth.
Oh, yeah, anyone can test my claim.
The objects I choose are photons. I shine them directly away from the Earth. According to my measurements, they are not slowed down at all, ever, regardless of how far they travel. There may be a change in frequency over distance, but I can exactly explain that purely with kinematics (i.e. geometry), without involving dynamics (i.e. forces) at all. They are not "pulled toward the Earth" in any sense.
You stand refuted. Goodnight.
You stand refuted. Goodnight. [excerpt]You have refuted my position very nicely.
Are you around any more?
