Time travel is real! In 2011, a special type of particle called a tachyon was detected. Tachyons can travel above the speed of light, and therefore back in time. This particle may have visited Albert Einstein when he was a baby! If a particle like this flew past you, you would see two separate objects.

Tachyons were long thought to not exist. Scientists in 2013 are still disputing over the discovery! It was discovered as part of the OPERA experiment, run using CNGS (CERN Neutrinos to Gran Sasso).

The particle is a neutrino, a tiny particle. Trillions of neutrinos are zipping through your body at this very moment. Don't worry, the vast majority don't hit anything. For a particle to go at the speed of light, it SHOULD take an infinite amount of energy. Impossible, right? Maybe not. Of course, this detection could be a false positive.
