  Well this explains why people believed in ghosts back in the day more than they do now.

    Whereas in the modern era, we document so much that there’s less of a reason to come visit?

      Exactly

  Unless you’re white it wouldn’t be great going too far back in time.

  White guy turns on time machine. Lands in feudal Japan. Isn’t Tom Cruise. Has bad time.

  Yes, as we all know, no other ethnicity has ever prospered in the history of mankind except white people.

    Everyone know old-school ghosts are white while RGB ghosts are modern innovation in the ghost world /s

  How am I supposed to become my own grandfather if I’m a ghost?

  If i could time travel as a ghost I would go back and Crusher OP’s mom.

  If you’ve ever watched the old or modern versions of Quantum Leap you know the routine: a “leaper” is time traveling by temporarily taking over the body of someone in the past, while another person from the traveler’s own time is supporting them remotely as a projected hologram only the time traveler can see and hear. The hologram can’t touch anything or communicate with anyone except the leaper in the past, but can zap around the past like a ghost to experience events without affecting anything directly.

  I’ve always thought that if you invented the hologram part of the Quantum Leap time travel scheme, you wouldn’t need the actual bodyswap time traveler part at all. You’d already have the safest possible form of time travel! You could remotely visit the past in hologram VR without accidentally stepping on a butterfly, changing winners of wars, dating your own mom, or otherwise screwing up the timeline in all the ways in which time travel scifi portrays. You could safely be an invisible time tourist from home all you wanted.

  If you travel to the future, are you still involved with the timeline or removed between the points of travel? This could have a major change in the timeline.

  If you are involved, you may now inadvertently screw up the sequence of events just by knowing the future.

  If you are removed, you now have to kill yourself as fast as possible while hiding your body to have minimal effect on to life or the environment. A lava pit might work.

    Or spend the rest of your life time-travelling

  Is time a physical space that you can ‘travel’ through, I have heard all about those fancy space-time continuums or something like that but I want someone to explain this to my smol brain.

    Sort of. You’re already doing it at this moment.

    Einstein showed that time is not a separate space, but is actually the same as any other dimension. However, we have not found any way to reverse our direction so far. We can only choose a direction to move forward in. In fact, you’re doing so when you get in a car; you’re experiencing a minor change in how you’re moving through time relative to those around you.

      It actually goes further than that. In spacetime you’re always going the same speed, the more in space, less in time.

      At least from the special relativity perspective.

    I’m traveling through time right now!

    Time is like space in that it can be distorted by gravity. If you get close enough to a black hole, then your perception of time will change compared to people on the outside. I don’t know why this is, it’s just a thing I know.

    Also, as you move faster then your perception of time slows down. For example, if you went in a rocket at a good chunk of the speed of light then returned, you’d only experience one year passing but people left behind on earth would experience two years passing. You would both be objectively correct because the time actually moves at different rates (it’s not just a perception change in your brain). This is proven to work with GPS satellites. They move fast enough in orbit that their clocks slow down ever so slightly, and this needs to be accounted for so that we can have accurate positioning.

    An analogy to understand this is to imagine a race across the desert. The finish line is 100m north of the start line. Two racers who move at the exact same speed are competing and set off at the same time. One person heads directly north, while the other one heads north-east. Who would get to the finish faster? Obviously the one who went directly north. Why? The other person wasted some of their travel on going slightly east. Now think of that same analogy with movement in time being north and movement in space being east. The faster you travel in space, the more of your movement through time is being “wasted”, so time slows down for you

  How would you interact to travel back to the present as a ghost?

    Not OP, but the controller for the time machine could be a ghost with you. Just like the spirits with Scrooge.
