MSNBC reports that Einstein’s theory of General Relativity has been shown to work on extremely large cosmic scales. http://www.msnbc.msn.com/id/35805184/ns/technology_and_science-space/ .
This is a great example of how the scientific method works. While Einstein’s theory of General Relativity has been shown to work very well on the scales that exist within our solar system, until now, 95 years after its publication, it was not able to be proven on very large cosmic scales.
The reason this is such a good example is that it shows that even though almost everyone agrees that Einstein’s theory of General Relativity is valid, we continue to test it.
This gets to the heart of the scientific method. Science is continually trying to improve our knowledge of the universe we live in. It is constantly moving forward in tiny little steps. Sometimes it has to move back a step or two when new experiments and new methods of testing show that a previously held theory is incomplete or incorrect.
In this case, Einstein’s theory of General Relativity is still correct, but we still haven’t proven that it is complete. In fact, this may be impossible because some of the things it predicts occur close to things like black holes or at near light speeds, and we may never have the technology test in these environment, but we will continue to move closer and closer to validating as much of the theory as we can.
This is just one example of how the scientific method is being used daily to try to validate or disprove a multitude of theories that affect all aspects of our lives. From relativity to quantum mechanics, gene theory to evolution, continental drift to the origins of our solar systems, the scientific method is the tool that allows us to continually improve our knowledge of the universe we live in.
