George McVittie (1904-1988), a British astronomer born in Smyrna (present-day Izmir, Turkey), left a lasting impact on the field of cosmology, particularly in the realm of general relativity. He was a key figure in bridging the gap between theoretical physics and observational astronomy, paving the way for a deeper understanding of the universe.
McVittie's journey began in Edinburgh, where he earned his degree in mathematics and physics. He went on to work at the Royal Observatory, Greenwich, before moving to the United States to teach at the University of Illinois. Throughout his career, he held positions at various institutions, including the University of London and the University of North Carolina, where he later served as a professor.

Task: Research and briefly describe one of George McVittie's significant contributions, beyond the "McVittie metric," that has had a lasting impact on cosmology. Include details about the contribution and its significance.
One of McVittie's significant contributions beyond the "McVittie metric" was his work on the **cosmological principle**. The cosmological principle is a fundamental assumption in cosmology that states the universe is homogeneous and isotropic on large scales. McVittie dedicated considerable effort to investigating this principle, particularly in his book "General Relativity and Cosmology." His research provided crucial insights into the nature of the universe's expansion and its implications for the distribution of matter. By exploring the mathematical framework of general relativity, McVittie demonstrated how the cosmological principle could be used to understand the observed expansion of the universe and the homogeneity of the cosmic microwave background radiation. This work provided a crucial framework for understanding the large-scale structure of the universe and paved the way for future advancements in cosmology.
