I'd draw the line between wild speculation and reality where you implied that it's possible for me to jump into the air and start flying. If the position of a particle can be measured with a probability function, then essentially everything is possible - even giving birth to a healthy, 2,000,000,000km tall baby, or walking through a solid brick wall without damaging the wall or yourself. To claim such things are even remotely possible is more than a bit of a quantum leap.
To be honest, I would have thought it less likely that matter could escape the event horizon of a black hole, but there we are...
Just because something is possible doesn't mean that it has ever happened, or ever will. This just appears to be the Universe we live in.
Oh... and as for our consciousness affecting reality.
I'm actually saying the opposite. Observation does not affect reality, observers are affected by reality (it just doesn't always appear that way all the time).
Imagine the Schrodinger's Cat scenerio. Schrodinger and Einstein mocked the idea that opening the box, observing the cat,
forced the cat to be either alive or dead. I'm speculating that the cat doesn't become either alive or dead, but that the observer becomes part of the superpositional state. He both sees a dead cat and a live one, but
something prevents the observer from viewing mutually exclusive realities. In essence, the Universe (or the perception of it) splits. One version of the observer sees a dead cat, the other a live cat. The mechanics of it, and what it implies for the concept of a consciousness, I don't claim to understand. And I am very ardently not claiming that a person has any ability to alter which version of reality they experience.
But, like I said, this is speculation. I accept the world as it appears to be according to the data until the data changes.
