The proof that science finds shows us how and what to do, like a blue print.
For most of us it improves our day to day lives in obvious and subtle ways.
We all get cell phone, because we have them and operate them in sophisticated way.
We all have medical care (some can afford better), but some of us don’t heed or understand the knowledge and practices that enable us to potentially live longer and healthier lives.
There are theories in physics that help us understand far more than what regular people pursue but specialists are planing trips to places on earth and beyond which may have some people visiting there, but who will soon be living there.
