1919-2000 · Physics, gravity, experimental physics
American physicist who first attempted the experimental detection of gravitational waves. He built the first resonant detectors (Weber bars) and claimed to have registered signals, sparking years of controversy. Although his results were not confirmed, he laid the foundations of experimental gravitational-wave astronomy.

Biography

Studied at the US Naval Academy, received his doctorate from the Catholic University of America. Taught at the University of Maryland. In the 1950s, he became interested in general relativity and the predicted gravitational waves. From the early 1960s, he built massive aluminum cylinders to capture ultra-small vibrations. In 1969, he announced the detection of waves, but other laboratories could not reproduce the result. Despite criticism, he continued to improve detectors. His ideas inspired the creation of the LIGO facilities, which in 2015 confirmed the existence of gravitational waves.

Key discoveries

💡 Weber's first detector was so sensitive that it registered vibrations from a truck passing a mile away. For isolation, he installed the device in an abandoned railway tunnel.

Moon Bell: A New Way to Catch Gravitational Waves

Scientists from the LILA mission aim to transform the Moon into a gravitational wave detector. Devoid of noise, the Moon will ring like a bell when hit by waves, and laser sensors will measure these vibrations. This opens the low-frequency band and lets us study black hole mergers right back to the

The Moon — a Giant Gravitational Bell

Computer modeling has shown that the Moon's uneven terrain and crust thickness turn its surface into an amplifier of spacetime ripples. In the region of the South Pole–Aitken basin, the signal is amplified dozens of times, paving the way for future lunar observatories capable of detecting the merger

The Conductor with a False Note: Why Quintessence Couldn't Save Inflation

The quintessential inflation model based on α-attractors describes inflation and modern dark energy as different roles of a single scalar field. Its key prediction is a kination stage, which amplifies high-frequency gravitational waves and leaves an imprint on the cosmic microwave background and pri

Moon Bell: How Gravitational Waves Unveil Lunar Secrets

Scientists have found a way to peer into the Moon's interior by using it as a detector of gravitational waves. Ripples in spacetime passing through the satellite cause it to tremble almost imperceptibly. By analyzing these tremors, the internal structure can be reconstructed ten times more precisely

Invisible Waves Make a Plate Ring

Scientists described the vibrations of an elastic plate when a gravitational wave passes through it. If the plate’s material does not expand sideways when compressed (like cork), the calculations simplify. Exact formulas for displacements and absorbed energy were obtained. The main discovery: the vi

Cosmic Palimpsest: Gravitational Waves Reveal the Story of Ancestor Black Holes

Analysis of two recent events from the GWTC-5.0 catalog showed that, with a probability 6–8 times higher than alternative explanations, the primary black holes in these systems were born in previous collisions. A Bayesian comparison of hypotheses favored the “2G+1G” scenario—a merger of a descendant
