A clock near a black hole will tick very slowly compared to one on Earth. One year near a black hole could mean 80 years on Earth.

With the timeline of Star Trek: Prodigy being quite confusing and complex, we thought it would be worth a video dedicated to the timeline of Prodigy? So strap in as we deal with Vau N’akat time travel, how prodigy fits in with Picard, and much more!
This is gonna be interesting because we first have to start with the Protostar, we will somewhat go chronologically down the timeline, but with time travel being involved, we will jump to relevant times to further explain things.

Black holes form natural time machines that allow travel to both the past and the future. But don’t expect to be heading back to visit the dinosaurs any time soon.
At present, we don’t have spacecraft that could get us anywhere near a black hole. But, even leaving that small detail aside, attempting to travel into the past using a black hole might be the last thing you ever do.

Black holes form natural time machines that allow travel to both the past and the future. But don’t expect to be heading back to visit the dinosaurs any time soon. At present, we don’t have spacecraft that could get us anywhere near a black hole. But, even leaving that small detail aside, attempting to travel into the past using a black hole might be the last thing you ever do.
A researcher has claimed time travel may actually be possible – and says he has the math to prove it. Time travel is a concept that has fascinated scientists for some time. It’s the idea that one can move to specific points in time, often seen in popular TV shows and films such as Donnie Darko, Back to the Future andNetflix’s The Umbrella Academy.
No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.
As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?
It’s a monumental head-scratcher known as the ‘grandfather paradox’, but a few years ago physics student Germain Tobar, from the University of Queensland in Australia, worked out how to “square the numbers” to make time travel viable without the paradoxes.
Traveling Back in Time
Posted in cosmology, education, media & arts, physics, space travel, time travel
Backwards through time? We travel forwards every day, but traveling back could let us change our past, visit old friends, or manipulate the timeline to our benefit… Although our knowledge of space and time remains incomplete, we can still use what we know to consider possible time machines. But what kind of paradoxes would this entail and how can we resolve them? Join us today on a special journey through time.
