I'm not sure if there will ever be a scientific instrument that can measure this. But I think there is a hidden spiritual energy that animates all life and gives us access to greater powers than we can possibly know.

I've always believed that there were masters at various times in history who had partially or fully realized this truth. However, I also think there is a lower, opposing power that seeks to prevent us from being aware of the unity of man. That is why there are so many false spiritual prophets, negative acts by various religions, and so much gross materialism that denies the existence of a spirit.

We've probably all touched a tiny piece of the universal spirit at least once, whether it was through making love, praying, meditating, enjoying nature, seeing a birth or a death, creating something beautiful, or just having a plain Zen moment.

This is all just my personal belief, but I find great comfort in in having a viewpoint like this. I think the main thing that prevents us from realizing unity more continuously is our own stubborn egos. I have observed how insidious my own ego has can be, and it is definitely something I am trying to be more mindful of so that I live life more fully.
