The Cosmic Microwave Background Radiation is at about three degrees above absolute zero, the coldest possible temperature. This radiation is one of the key pieces of evidence students learn about at GCSE which supports the Big Bang theory. The ideas about how it could be so uniform are quite mind-blowing. The article throws up some good discussion points about how science works. Should we be fiddling with problems to try to make the established theories hold or will there be a major revolution to bring in a whole new way of thought. This is a suitable topic for scientific enquiry perhaps looking at the Copernican Revolution, as well as that brought about by Einstein. Do we have an obsession for getting to a fundamental truth, a theory of everything? Could we contemplate a universe where the laws we hold true didn’t always work. It could make for some lovely imaginative work, but would shake our ideas of the foundations of science. Perhaps our students should be urged to challenge their established views of the world - after all Einstein said that “commonsense is the collection of prejudices acquired by age 18”.
