Lisa Randall's research is super important! ๐
One of her big ideas is about a hidden dimension in our universe. She published a paper in 1999 about a new theory called "extra dimensions," which explains why
gravity is weaker than other forces. ๐
This helps scientists understand why we don't see the force of gravity as strong as we feel it. Lisa also works on understanding "dark matter," which is a mysterious substance that makes up most of the universe! ๐
Her discoveries open up new questions about science and help scientists look beyond what we already know.
