I wanted to ask a question so I created an account!

Heya! I was browsing the net as usual and suddenly I was struck with a weird question about time travel. I don't know why my brain decided to pop this question all of a sudden when I wasn't even doing anything science related things. Anyways, my question follows:

Vers.1: Let's say, today, I was playing a different kind of d&d and the dice had 100 sides. I rolled 25. After a week I found a time traveling car and decided to turn back to the moment where I rolled 25. This car also has a gimmick where it makes you only a spectator meaning that you can't interact with anything or change anything.

Now, my question is if I can see myself rolling a number other than 25? If not why is that? 

There is also a slightly more different version of this question. 

Vers.2: It's still the same question as the Vers. 1, but this time the dice is not physical, you roll it on the internet or whatever. It's not affected by the temparature, noise, heck even the radio waves.

Thank you for the answers in advance.

PS: I'm not familiar with this forum. As soon as I was struck with the question I typed the words "Science Forum" and created an acoount here so...

If this car makes you only a spectator, then how is it different from somebody taking a video of you rolling the dice and then replaying the video a week later?

We're observing the event, which means universe still acknowledges our existence in other words we still have mass even if it's a miniscule one.

Why wouldn't we be seeing a different result?

Do you mean that you+car's mass went back in time one week? How does it work with the conservation of energy?

Also this rule should be intercepted as "you can't change the variables which affected the result of rolling 25".

How can you or anybody know which variables affect or not the result of the rolling? Do the presence of you+car's mass, extra weight on the floor, changed resonance frequencies, air disturbance caused by you+car, etc. affect the result or they do not?

Yes and Idk.

We can't know the variables. Umm, yes there is extra weight but it's incredibly miniscule. I mean you can't exist without having a mass (to my knowledge) but assume that the "car" has an effect that reduces your actual weight, makes you invisible etc. Those rules are just the things I made up to simplify things, don't think about the actual real world physics. What I really want to know is that if it's actually possible to get a different result when you go back in time with such restrictions. I mean you should be getting a different result everytime you go back and see the roll yourself. no? Like, you obviously can change it if you intervene with it. But it should have a different result even if you don't intervene with it because you are still concious and the world should still be processing the variables and outcomes.

That's the reason why I made 2 versions of the same "rolling the dice" situation.

I don't know what it means, to go physically back in time and at the same time not to -

As I don't see, how one can think about what is -

actually possible

These statements seem self-contradictory to me.

If it's possible to travel back in time as an observer, then there must be a record of time to observe. You would only be able to view what is recorded. Therefore, you will only see 25 because that's what would be recorded. If you had it on video, you're not going to see it roll 24 are you?
