A singular answer brought out of the question
Science is a wonderful tool. It's only a tool. It doesn't form big questions, and it doesn't answer them. We do.
There are no cute people here.
Therefore, no one is meditating.
The truth is amazing and not what we "think." It's counter-intuitive in that it goes against our assumptions. Truth is intuitive, but "intuition" has been turned upside down: Originally it meant directly knowable (a priori). It still does in science. But in psychology we use intuitive to mean "what one would guess or assume."
Dr. Quantum explains counter-intuitive findings in physics ("What the Bleep Do We Know").
Like psychology Newtonian physics was intuitive. Like science quantum physics turns our world upside down. Both are true in their own domains. An easy way to picture it is staring at the TV. We see pictures. But look more closely: there are no pictures, just pixels. Both are true. There both, and there is not one without the other.
In just the same way the Buddha talks about conventional truth (what happens in the world of sense experience) and ultimate truth, what really happens and to whom.
Who am I, who is experiencing meditation, who is doing the watching? Is the answer "Christy Turlington"? No, the Five Aggregates are.
That's unbelievable. But it can be checked directly, that is, you can check. "You" is just a convenient way of referring to the Aggregates. Meditating (watching, observing, knowing) changes everything.
If we begin to sense the truth -- non-duality, interdependence, oneness, the unity of all things -- it can feel like all that came before was not real. But it was real in its own domain. Both things are true. But it is the ultimate truth that holds more significance.
So when the Buddha and teachers say things from that point of view, they have to be considered from that point of view to avoid confusion.
