At the Large Hadron Collider, scientists have transformed lead into gold—a process known as chrysopoeia, which alchemists sought for centuries.

NASA economic impact (and budget history)

It's estimated that for every dollar NASA spends on its programs, $8 is produced in US economic growth. With a 2023 budget of roughly $25 billion, that means NASA helped create $200 billion in economic value. The administration's investments pay off so massively due to the technologies it develops, many of which become commercially appealing. Dive into the economic impact of NASA's development here.

Watch an animated visualization of how the Large Hadron Collider works, including how particles are accelerated through a series of machines and how collision data is collected and distributed worldwide.

As of 2026, 75 of the 86 particles discovered by the Large Hadron Collider have been found by the LHCb experiment—a detector that explores the decay of particles made of beauty and charm quarks.

Take a 360-degree tour of ATLAS, one of two general-purpose detectors at the Large Hadron Collider and the largest particle detector by volume ever built. (VR device-compatible)

View the most expensive materials on Earth, led by antimatter and other elements forged in particle accelerators.

The Manhattan Project, the top-secret American program that built the world's first atomic bomb, cost $27B in today's dollars and reshaped global power.

Extending the worldwide lifespan by one healthy year is worth $38T

This econometric study attempts to estimate the economic value of increasing the global healthy lifespan by one year—and to answer the question of whether it is better to extend lifespans or slow the rate of healthy aging.

Some cosmic rays possess energies as high as 100,000,000 teraelectron volts—more than 10 million times the energy of particles accelerated in the Large Hadron Collider.

More than 97% of the world's particle accelerators are used for commercial purposes

Only a few hundred of the over 30,000 particle accelerators worldwide are used for research. Most are involved in medical imaging and treatment, food sterilization, semiconductor processing, cargo screening, and radioisotope production. They're also used to modify the properties of polymers.

Particle accelerators propel matter toward small targets at high speed

Devices like cathode-ray tube televisions were once basic particle accelerators, but modern ones, such as the Large Hadron Collider, use massive magnetic fields and circular tunnels to achieve energies high enough to recreate the conditions just after the big bang.

Before 1932, when particle accelerators were first used for nuclear research, scientists relied on naturally radioactive substances to advance their understanding of the atomic nucleus.

The NSF funded the design and construction of LIGO by MIT and Caltech

The 1992 Cooperative Agreement between the National Science Foundation and both research institutions came twelve years after funding 1.5-meter (4.9-foot) and 40-meter (131-foot) prototypes. With a 1992 budget of $395M, LIGO was once one of the largest NSF-funded projects in history

At CERN's Antimatter Factory, researchers create and guide antiprotons and antielectrons together to form antihydrogen, and all these antiparticles are analyzed to help scientists study the behavior of antimatter.

Lyme disease may cost about $1B annually in the US

The economic burden of the disease in this estimate includes direct medical costs and societal costs, including productivity losses. It does not include suspected, undiagnosed, or nonacute cases, which would push that figure upward.

As of 2022, about 40% of scientific research aimed at generating new knowledge has been funded by the federal government—a percentage that has decreased from a high of 72% in 1967.

An analysis of the National Science Foundation's historical budget and spending

The NSF accounted for 0.1% of all federal spending in FY2024, with $9.39B—just over twice its FY1991 spending—out of $6.78T overall. Almost 99% of these funds ($9.29B) went to general science and basic research, with the rest allocated to national defense.
