The fact that "you" are in free fall indicates you are a body of some kind. If you have any mass, you have gravity. If you have gravity, it is possible, in principle to detect and measure it.

How? Physicists around the world are waiting with bated breath to hear how you are going to do it.

Te earth is a body in free fall. You can measure the gravity of the earth. Which is exactly what I said in my previous post.

I’m not trying to be cute. I agree that in free fall you can’t detect acceleration or the source of acceleration. But you can, in principle, detect your own gravity.
