Have you ever thought about where time came from, or how space started? These are some big questions people ask in science, and now, a brand new technology called 4D quantum sensors can help us solve those questions. A lot of sensors we use these days can only measure things in three dimensions, like, length, width, and height. But 4D quantum sensors can do things even further than that, they also measure time as if it’s its own direction. These sensors are very sensitive. They can sense some little tiny, invisible changes in space and time, even the ones that happened right after the Big Bang. Some scientists think that space and time didn’t always exist. Instead, they made out of a strange, fuzzy state called a quantum field. These sensors might help us “see” what happened as the universe went from that state into the space and time we live in today. Research centers like Caltech and the European LightCone Observatory are already using these sensors in high tech labs. They’re hoping to catch signals or tiny patterns left over from the beginning of the universe. If this technology can work, it could completely change how we think about the universe. It might even lead to new inventions, like super fast computers or better tools for exploring space. Thanks to these powerful 4D quantum sensors, we may soon be able to see the moment when time and space were born.
