"Can ghost be scientifically measured"?

The question is, what to do after you can measure it?

about these ghost things, i would say there is more important things need to be discover.

As the ghosts, we could not see them every day, day and night, there is nothing you can check to confirm. Like a biscuit, kadang2 ada.

We also could not predict where it comes from, or what is a physical values of these ghosts.

Until you can put it in the "bottle" and test it, then, you can know what it is.

But, what we gonna do after we found the physics value, turn the ghosts into a electric generator?
