他們還沒有可靠，並且可以被認為是試探性的科學或前沿科學。一些有結果將驗證和歸類為可靠和一些將名譽掃地，歸類為不可靠的。
At the frontier stage, it is normal for scientists to disagree about the meaning and accuracy of data and the validity of hypotheses and results. This is how scientific knowledge advances.

1.3.5

Nonrenewable resources exist in a fixed quantity or stock in the earth’s crust. On a time scale of millions to billions of years, geological processes can renew such resources. But on the much shorter human time scale of hundreds to thousands of years, these resources can be depleted much faster than they are formed. Such exhaustible resources include energy resources (such as coal and oil),metallic mineral resources (such as copper and aluminum), and nonmetallic mineral resources (such as salt and sand).

不可再生資源中存在一個固定的數量或庫存在地殼。時間尺度的數以百萬計的數十億年的時間，地質變化過程中可以延長這類資源。但在更短的時間尺度人類數百至 數千年來，這些資源可耗竭速度遠遠超過它們的形成。這種耗盡資源包括能源資源（如煤和石油） ，非金屬礦產資源（如銅，鋁）,以及非金屬礦產資源（如鹽和沙子） 。
