The structure of the universe is a complex and fascinating topic that has intrigued scientists and laypeople alike for centuries.  It is a vast expanse of space that contains everything that we know of, from stars and planets to galaxies and superclusters. Understanding the structure of the universe is essential to understanding our place in it and the fundamental laws of nature that govern it. At the largest scale, the universe appears to be homogeneous and isotropic, meaning that it appears the same in all directions and at all points in space. This is known as the cosmological principle. However, at smaller scales, the structure of the universe is highly varied and complex. The basic building blocks of the universe are subatomic particles, such as protons, neutrons, and electrons. These particles combine to form atoms, which in turn combine to form molecules, and so on. At larger scales, these molecules combine to form stars, planets, and other celestial bodies. The universe is...

One of the greatest scientific successes of the past century was the theory of the hot Big Bang: the idea that the Universe, as we observe it and exist within it today, emerged from a hotter, denser, more uniform past. Originally proposed as a serious alternative to some of the more mainstream explanations for the expanding Universe, it was shockingly confirmed in the mid-1960s with the discovery of the “primeval fireball” that remained from that early, hot-and-dense state: today known as the Cosmic Microwave Background. For more than 50 years, the Big Bang has reigned supreme as the theory describing our cosmic origins, with an early, inflationary period preceding it and setting it up. Both cosmic inflation and the Big Bang have been continually challenged by astronomers and astrophysicists, but the alternatives have fallen away each time that new, critical observations have come in. Even 2020 Nobel Laureate Roger Penrose’s attempted alternative, Conformal Cyclic Co...

James Webb, in full James Edwin Webb, (born October 7, 1906, Tally Ho, North Carolina, U.S.—died March 27, 1992, Washington, D.C.), American public servant and administrator of the National Aeronautics and Space Administration (NASA) during the Apollo program (1961–68). After graduating from the University of North Carolina at Chapel Hill in 1928, Webb became a marine pilot. He began his government career in 1932 as a congressional aide in Washington, D.C., and from 1934 to 1936 he studied law at George Washington University. He worked for Sperry Gyroscope from 1936 to 1944, when he reentered the Marine Corps for the remainder of World War II. During the administration of Pres. Harry Truman (1945–53), Webb was director of the Bureau of the Budget and undersecretary of state. When Truman left office, he went to work for the Kerr-McGee Oil Company in Oklahoma. Webb became the administrator of NASA in 1961, just months before Pres. John F. Kennedy announced the U.S. commi...
