Please drop this whole cat point as well. It's making you look desperate. You're obviously fumbling here.
Sure: when you tell me how you are assured it isn't one great big hallucination or pretension. It's an illustration you've yet to acknowledge. You're saying that everything that's been given to you as proof of gravity isn't enough because it could be explained away by numerous other proposed concepts: but that's true of everything. Do you disagree, and if so, why?
I've decided to entertain BiJane's massive strawman argument for laughs.
May I present.... Digit, my cat. He is angry that I made him do this, as you can tell.
Satisfied now, BiJane? If you think it's shopped, please show proof of it being shopped. If you think it's a halucination, well... I'm sure everyone else can see the picture so that's not a valid excuse anymore.
Now that your strawman has been utterly maimed: could you please present us with direct evidence for gravity? A picture of gravity would do nicely, I think.
I'll wait.
