They may also change it to see how the change alters the results
Well the atoms are never going to change but, as you can see the more scientists study the atom we have the ability to add to our technology.
A one-Angstrom microscope allows scientists to see individual atoms. At this scale, scientists can study the arrangement and behavior of atoms within materials, which is essential for understanding the properties and behavior of matter at the atomic level.

Climate scientists believe climate change is real and is of concern because they understand the science involved and the factors that contribute to the climate, what controls it, and what is happening that makes the climate change. They also see and understand how the climate is changing and why it is happening.
