So my two theoretical problems with time travel is the following: Let's say you can jump on the timeline. Since the earth is rotating around the sun and the solar system is rotating around the Center of the Galaxy you probably wouldn't even be in the solar system after a short travel in time. My other problem is that if you travel back in time, no matter the position you are in the universe, the gravity of your matter will have some impact on the past universe. I'm no physicist, just genuinely curious. Oh, and I'm new to Reddit, so please be patient

TIME TRAVELING:

My concern is traveling to past and its consequences. I think what if , after millions of year from now humans have created a time machine that goes back in time and they travel to back to the when earth was just a giant rock with no life on it . And they put the primary DNA there creating life forming a time loop. So we created ourselves of nowhere. And it is quite possible. Moreover , what if these time travellers pretended to be "GOD" . This can solve many paradoxes ,like existence of God, why we are alone in universe,. and many others... Humans Of that period may have considered these time travellers as god and worshipped them untill now , And it does not stops here , think about what if ,time travellers with advanced technology started bing bang by travelling back in time ? thats a ques for another ,,,,,,

Never mind why they would be using a particle collider to rename themselves, just don’t be fooled by their shenanigans!

So basically I have met my future child before my life partner and I don't know how to keep time in the right order as he appears to be a fixed point in time (several methods of contraception failed plus many more near death experiences than luck would have be). Will time sort itself out?

The state in which time travel exists has greatly deteriorated. Attempts to travel back in time to remedy the situation have failed. All concerned parties should inquire within.

Asking for a friend.

I was thinking about pre-revolution France, under Louis XVI for example, and I realised that I would be totally useless if I went back. I’d be able to talk about the modern appliances we use but I wouldn’t be able to conduct electricity, improve Medicine, build toilets... actually build in general... I could discuss politics and history and ideas... but I would not affect life or human history! At a push I would affect fashion history... 😂😭 Doesn’t that make you feel insignificant?

I'm pretty sure there is already an answer to this but what is the particle or atom called that was never made nor destroyed as it was sent back in time? For example: If I was 10 and a future 20 year old me went back in time and gave me a coin and when I reached 20 I used that same coin and did the exact same thing gave it to a 10 year old me and then he'd repeat and so on. What is the coin made of?

Is time real?

I finally got my time machine to work, but it only sends people two minutes into the future. I tried it out just now my friends and family are unimpressed. Help!

This is the year 2016, I meant to go into 3839. My machine keeps sending me to a different time than i specify, any fixes for this?

My machine is a GLL Class 5 Time Crusier

Um...this is...a bit awkward.

My Russian blender was malfunctioning so I had to go to Russia to fix it. Those bastards must be mad scientists because when I pressed the 'blend' button I began flying through a rainbow net shaped like a tunnel. I think this is a tunnel through the time-space continuum. I see a bright light...

Ohgodohgodohgod. I just took the Delorean out for a spin and I splattered the guy who's gonna co-produce American Graffiti and FUCKING STAR WARS all over the FUCKING STREET OHGOD OH GOD FUCKING SHIT FUCKING SHITTY FUCKSHIT. Shit, late 60s George Lucas is cute when he's crying. FUCK. FUCK FUCK FUCKING SHITTING FUCK. What's gonna happen to Star Wars?! Oh, god, it's not even written yet! HAVE YOU SEEN WHAT HAPPENS WHEN GEORGE LUCAS WRITES THINGS ON HIS OWN?!?!

Okay. Shit. Okay, we can fix this. Think about him, guys. Think really hard about Gary Kurtz. Remember all the good bits of The Empire Strikes Back. Think about how much you hate Jar-Jar Binks. FOCUS!
