Key Findings

Scientists want to use an experiment to confirm that <a href="https://www.popularmechanics.com/science/a36701159/charm-mesons-particle/">elementary particles</a> have measurable mass. It would involve a matter-<a href="https://www.popularmechanics.com/space/deep-space/a34272429/how-much-matter-is-in-the-universe/">antimatter</a> annihilation process that would shoot a beam of positrons at electrons in a piece of metal. Positrons and electrons are both subatomic particles, with the same mass and magnitude of charge. However, <a href="https://www.popularmechanics.com/space/deep-space/a37224743/physicists-generate-antimatter-in-the-lab/">positrons</a> are positively charged, and electrons are negatively charged. A sheet of metal has many free electrons, increasing the probability of collision with the incoming positrons.

Information Being A Form Of Matter: The backstory

The amount of information we have today is staggering. Each day on Earth, we generate 500 million tweets, 294 billion emails, 4 million gigabytes of Facebook data, 65 billion WhatsApp messages, and 720,000 hours of new content added daily on YouTube.The total amount of data created, captured, copied, and consumed in the world was 59 zettabytes in 2020.One zettabyte is 8,000,000,000,000,000,000,000 bits.Proving that information has mass through physical experiments is the first step toward finding a possible solution to the problem of explosive information growth.

Information Generated Every Day

Proving that information has mass can explain mysteries like dark matter. That’s because the physical properties of the bits of information mimic what dark matter appears to be—small bits of mass particles without charge or spin.Confirming that information is the fifth state of matter touches on a weird idea: that the universe is actually a computer simulation. As an academic exercise, scientists have <a href="https://watchdocumentaries.com/the-simulation-hypothesis/">suggested this idea before</a>. If information is indeed a key component of everything in the universe, then perhaps a computer somewhere is running our whole world as a simulation.

Beyond Our Earthly Problems: The Universe May Be A Simulation After All

Scientists believe that the observable matter in the universe has specific information content. For example, typical atoms—containing protons, electrons, and neutrons—hold not only the combined masses of these subatomic particles, but also the minuscule masses of the information they require to interact with each other and the rest of the universe. This type of information could be considered the <a href="https://www.popularmechanics.com/science/a33327626/scientists-encoded-wizard-of-oz-in-dna/#:~:text=%22A%20teaspoon%20of%20DNA%20contains,internet%20in%20a%20shoe%20box.%22">“DNA”</a> of the particles.

A New Concept of Matter

If true, this idea could even help us understand all of the dark matter in our universe.
