About Rainer Weiss

Rainer Bruno Weiss (born April 30, 1932) is an American physicist and astrophysicist of German descent, best known for his pivotal role in the discovery of gravitational waves. Born in Vienna, Austria, Weiss fled with his family to the United States during World War II. He grew up in New York City and completed his undergraduate studies at Cornell University, where he developed a passion for physics under the tutelage of Richard Feynman. Weiss continued his academic journey at MIT, earning a PhD in Physics in 1962. His doctoral thesis, titled "Coherence Lengths and Time Constants of Quantum Fluctuations in the Early Universe," foreshadowed his lifelong interest in cosmology and quantum mechanics. After a brief stint as a professor at the University of Maryland, he returned to MIT in 1967, where he has spent the majority of his career. In 1974, Weiss, along with Barry Barish and Alan Riess, proposed the Laser Interferometer Gravitational-Wave Observatory (LIGO). This groundbreaking project aimed to detect gravitational waves, ripples in spacetime caused by cataclysmic cosmic events such as the collision of black holes. After decades of development and refinement, LIGO made its first successful detection in 2015, a monumental achievement that earned Weiss, Barish, and Riess the Nobel Prize in Physics in 2017. Throughout his career, Weiss has been a prolific researcher, publishing numerous papers on topics ranging from quantum mechanics to cosmology. His work has had a profound impact on our understanding of the universe, particularly in the field of gravitational physics. Despite his many accomplishments, Weiss remains humble and committed to advancing scientific knowledge for the benefit of humanity.

"The joy comes from the pursuit of understanding, not from the understanding itself."

Rainer Weiss suggests that the true pleasure derived from a task or endeavor lies in the process of seeking comprehension, rather than solely attaining it. The journey of discovery, exploration, and investigation is what brings us joy, enrichment, and fulfillment. The destination (understanding) serves as a goal, but it's the steps taken along the way that provide meaning and satisfaction. This quote encourages an appreciation for curiosity, learning, and personal growth, reminding us to embrace the process, not just the outcome.


I didn't understand the Weber bar and how gravitational waves interacted with it. I sat and thought about it over a weekend, trying to prepare for the lecture for the following Monday. I asked myself how would I do it. The simplest way... was a thought experiment.

The waves travel with the velocity of light and slightly squeeze and stretch space transverse to the direction of their motion. The first waves we measured came from the collision of two black holes each about 30 times the mass of our sun.

I said, suppose you take a light - I was thinking of just light bulbs because, in those days, lasers were not yet really there - and sent a light pulse between two masses. Then you do the same when there's a gravitational wave. Lo and behold, you see that the time it takes light to go from one mass to the other changes because of the wave.

All at once, funding was gone due to the Mansfield Amendment, which was a reaction to the Vietnam War. In the minds of the local RLE administrators, research in gravitation and cosmology was not in the military's interest, and support was given to solid-state physics, which was deemed more relevant.

We know about black holes and neutron stars, but we hope there are other phenomena we can see because of the gravitational waves they emit.

- Rainer Weiss

We've seen black holes, which is already wonderful. We also expect to see the merger of neutron stars, and that was a thing that actually gave this field a certain credibility when it was discovered that there were pairs of neutron stars in our galaxy, and people stopped laughing at us when that was found out.

It's a spectacular signal. It's a signal many of us have wanted to observe since the time LIGO was proposed. It shows the dynamics of objects in the strongest gravitational fields imaginable, a domain where Newton's gravity doesn't work at all, and one needs the fully non-linear Einstein field equations to explain the phenomena.

I thought that there must be an easier way to explain how a gravitational wave interacts with matter: If one just looked at the most primitive thing of all, 3D floating masses out in space, and look at how the space between them changed because of the gravitational wave coming between them.

- Rainer Weiss

Thought, Explain, Primitive, Floating

The obvious thing to me was, let's take freely floating masses in space and measure the time it takes light to travel between them. The presence of a gravitational wave would change that time. Using the time difference, one could measure the amplitude of the wave.

By the time 1967 had rolled around, general relativity had been relegated to mathematics departments... in most people's minds, it bore no relation to physics. And that was mostly because experiments to prove it were so hard to do - all these effects that Einstein's theory had predicted were infinitesimally small.

Einstein had looked at the numbers and dimensions that went into his equations for gravitational waves and said, essentially, 'This is so tiny that it will never have any influence on anything, and nobody can measure it.' And when you think about the times and the technology in 1916, he was probably right.
