A scientific theory is a broad explanation for events that is widely accepted as true. A hypothesis is usually written in the form of an if-then statement, which gives a possibility (if) and explains what may happen because of the possibility (then). Following Eric Weinstein's interview on how String Theory culture has stifled innovation in theoretical physics, longstanding critic of String Theory, Peter Woit, takes aim at the theory itself.

Then the area is subjected to a temperature of 8C-8^{\circ} \mathrm{C}8C and high winds that result in a convection heat transfer coefficient of 40W/m2K40 \mathrm{~W} / \mathrm{m}^2 \cdot \mathrm{K}40W/m2K on the earth's surface for a period of 10h10 \mathrm{~h}10h.

The theory of evolution by natural selection explains how living things are changing today and how modern living things have descended from ancient life forms that no longer exist on Earth. Karl Popper, "The Logic of Scientific Discovery," Routledge, 1959. For example, one extract chlorophyll from grass and observe the color of the extract and ah, off the remaining grass.
