Danny Faulkner of AIG backs Einstein
"Over the years, the predictions of general relativity have been tested repeatedly, and it is one of the best-supported theories in the history of science." -Faulkner
General relativity predicts that the universe has been expanding over vast time. This prediction was first made by Alexander Friedmann and Georges LemaƮtre in the early 1920s, shortly after Einstein published his theory of general relativity.
In 1917, Willem de Sitter used Einstein's equations to predict the discovery of an expanding universe.
A letter from Albert Einstein to astronomer Willem de Sitter, complaining that the expanding-universe theory implied a moment of creation: “To admit such possibilities seems senseless to me.”
Friedmann and LemaƮtre showed that general relativity predicts that the universe should expand and dilute with time, as a result of the gravitational attraction of all the matter and energy in the universe. This expansion would cause galaxies to drift away from each other, and the light from distant galaxies would be redshifted, as the expansion would stretch the wavelengths of light.
These predictions were confirmed by observations made by Edwin Hubble in the 1920s. Hubble found that the light from distant galaxies was indeed redshifted, and that the amount of redshift was proportional to the distance of the galaxy. This is known as Hubble's law, and it is one of the most important pieces of evidence for the expanding universe.
Since Hubble's discovery, observations of the expanding universe have become even more precise. These observations have shown that the expansion of the universe is accelerating, which is a phenomenon that is not yet fully understood. However, it is thought to be caused by a mysterious form of energy known as dark energy.
The expansion of the universe is one of the most important discoveries in modern cosmology. It has profound implications for our understanding of the universe, and it is a topic of active research.
