Similar things have happened before with other scientific photos.
Oh yes, that’s what THEY told you.
How do you ever know?
How do you ever really know?
Sigh!
I agree with you that just because someone says it’s happened with other photos doesn’t mean we should believe them. But watch any old movie an you’ll see film grain. Also, why would a light stop all of a sudden after reaching a certain height, instead of fading out gradually?
