Have you ever wanted to go back in time?
Two scientists now think time travel might not be science fiction.
Professor Amos Ori is an eminent physicist who thinks time travel might be a possibility for future generations.
He has set out a theoretical model for a time machine, which is based on a series of mathematical equations.
His equations show that time would be able to curve back on itself so that a person travelling around the loop might be able to go further back in time with each lap.
It's been described as a doughnut of space time.
Another scientist called Dr Ronald Mallett, has only recently spoken out about his time travel research as he thought other scientists might think he was a crackpot scientist.
His theory is called space time twisting by light.
Dr Mallett was inspired by a novel written in 1895 called The Time Machine, by the writer H G Wells. He read it when he was ten years old after his father died, and the novel gave him hope that he might one day be able to go back and save his father's life.
