Scientists Rule Out Another Place Where Tiny Black Holes Might Hide

Topic: Physics

Physicists at UC Santa Barbara searched for tiny black holes at the Large Hadron Collider. They didn't find any, but their results help us understand how the universe works.

Physicists at the University of California, Santa Barbara (UCSB) have been searching for a long time to see if they can create tiny black holes at the Large Hadron Collider (LHC). The LHC is a huge machine that smashes protons together at very high speeds. If they could make tiny black holes, it would help them understand some big questions about space and gravity.

The team used a new technique to search for these tiny black holes. They looked at the data from many proton-proton collisions and tried to find any signs of tiny black holes. But they didn't find anything. This might seem like a disappointment, but it's actually very useful information.

When scientists don't find something, it can help them rule out where that thing might exist. In this case, the team was able to say with certainty that if tiny black holes existed with certain properties, they would have seen them by now. This helps narrow down their search and gives them a better idea of what to look for next.

The researchers are excited about their results because they can help us understand some big puzzles in physics. For example, there's a huge difference between the size of the universe we experience and the tiny scale at which quantum gravity works. Scientists have proposed many theories to explain this difference, but none of them have been proven yet.

The team's work is published in a journal called Progress in High Energy Physics (PHEP). They used data from the LHC collected between 2016 and 2018.

Why It Matters

Understanding how tiny black holes might form can help us learn more about space, gravity, and the universe. It's also an important step towards unifying all the forces of nature, which is a big goal in physics.
