Time travel reddit will exist yesterday

Welcome to Time Travel

DEFINITION

"An object time travels if and only if the difference between its departure and arrival times as measured in the surrounding world does not equal the duration of the journey undergone by the object."

---The Internet Encyclopedia of Philosophy


OVERVIEW

This subreddit is about time travel.

Specifically, it is about the philosophical, scientific, technical and metaphysical aspects of time travel, with a sprinkling of media references to help things along.

Join us here to discuss the topics that will one day allow us to explore the four-dimensional continuum - or at least get older trying.

Please note that this is a non-fiction subreddit.


POSTING GUIDELINES

Here's a summary of the types of post that are appropriate and not appropriate for this subreddit:

THEORY posts. These involve discussion of a particular theory of time travel. This may be philosophical, scientific, technical or metaphysical.

DISCUSSION posts. These posts involve raising a topic for discussion, maybe in the form of question or speculative scenario. "What ifs" and "What would you dos" are appropriate. here.

MEDIA posts. This may consist of discussion of or links to fictional or documentary material that's relevant to the subreddit, such as films, books, TV series, exhibitions.

META posts. For posts which are about the subreddit itself or broader issues relating to the topic.

ARTICLE posts. These are any links to articles about time travel found elsewhere on the web.

CHALLENGE posts. Challenge posts are to discuss and clarify various challenges related to time travel. Discussions of tomorrow's newspaper, Dinosaur video, Time Machine schematics, and future predictions all fit this tag.

No fictional or AMA-style posts. You are very unlikely to be a time traveler. And if you are, we are only interested in reading highly detailed posts about the technical and theoretical aspects involved. Please send a mod message if you wish to do an AMA post. Claims without proof will be ignored and removed. This is not a creative writing sub. Links to claims and hoaxes elsewhere on the internet are fine.

This last point includes broken clock posts. A broken clock (one not telling time properly) is not a sign of time travel, and making such a claim falls subject to the roleplay/fiction and/or claims (which require evidence, more than just your clock). Clock posts showing the results of time dilation experiments are allowed.

If you wish to have more relaxed rules and freely make claims, visit /r/timetravelhub.

bad idea on how to get rich

  • You travel back in time to prevent 9/11, bringing along a manuscript of “Twilight”

  • Gerard Way never makes MCR

  • Stephanie Meyer never makes Twilight

  • You release Twilight under your name

  • make bank

Pros you get rich

Cons you have to stop 9/11 (very difficult) MCR ceases to exist

Time travel and sports betting

Have time travelers already affected sports betting? Would we even know? If you’re in to sports, I think we can all agree that the frequency of questionable calls, missed passes/hits/throws/etc. is a little TOO convenient. How would a time traveler use information to affect change in Vegas?

Just a reminder...

December 8th is Pretend To Be A Time Traveler Day. I think Admins had posted as a heads up!

The Time Capsule Paradox

Knowing the workings of this title while working on my time-battery (electrical/frequency solution), here's the theory.

You were enjoying a glass of wine and learned about the benefits of its ageing process and considering the value of that experiment,

You had made two bottles of wine and used a time machine to travel back to (say) before the jurassic era and bury them in separate locations to age without disrupting to the STC,

One of the bottles will be found and delivered to your local wine cellar for you to start the loop,

The second will be burried under the location where your house will be built for you to dig up once you returned from the past, ending the loop.

When I travel back to 12/12/2023, to advise my past self about the dangers ahead in exchange to start the research a week early while enjoying the happiness and peace,

The alternative is when I send noted messages from my phone (powered by the time-battery) to points of my past in different order to ensure the research exists AND erase the problem.

Instantaneous Travel vs Faster Than Light Travel

One is usually shown in fiction to cause time travel (Justice League Snyder Cut with FTL) yet in the same movie, Darkseid opens a portal and Steppenwolf’s corpse is thrown threw it. Did he get thrown to the past?

I know it’s science fiction, but it’s interesting. Instant travel is faster than FTL travel, but from my understanding FTL seems to be the one associated with time travel.

Does it have to do with perception and what’s relative to the observer?

If you time travel back in time with With a Flash Drive Stick in Hand, would it get melted while time travel

I'm a very curious person who's wondering what will happen if I did bring it in hand. What type of safety container to project my Flash Drive?

The butterfly effect

I think the butterfly effect is overstated. There are a multitude of people in present time that will lead boring insignificant lives that don’t change the world in any way.

As crass as it sounds, someone not being around at a certain place/time won’t have monumental changes to time because they don’t move the needle

Guys

I was watching Peabody and Sherman and realized “can’t you just go back in time for no reason and do whatever you want? Because if you go back in time to kill hitler or something you’d make a paradox.”

Time dilation

I’m confused about time dilation. If travel to andromeda and back in about 10 minutes then shouldn’t I have only been gone for 10 minutes on earth? I’ve been trying to vision it but I just can’t.

How far is a planet where 1 Day there is a 1000 years on earth?

In Interstellar, time dilation is wonderfully explained on Miller’s planet. Like 1 hour on it is a whole 7 years on earth. And that was like few hundred light years away from earth if traveling near black hole or worm hole. I want to know how far would a planet be from earth where 1000 years here is like 1 day there. For them evolution of human only began 15 days ago.

A time traveler walks into a bar, but the bartender refuses to serve him.

"Why the hell not?" the time traveler asks.

"We don't serve any time travelers here," the bartender explains, "not since one got stinking drunk and trashed the place four years ago."

"Four years ago, you say..."

Compression and Solar Flare interference during travel?

Just a random thought, when you consider time travel, would you go through intense compression during the parallel universe bending? Or am I way off the theory?

Say you schedule a meeting for 2:15pm on Cyber Monday, and you travel on Black Friday, but are compressed to where you can’t make the meeting in person and now need to make a call - is the meeting today? Tomorrow, or yesterday once you’re out of the hospital?

Can telecommunications work off the network? Or is a message via fax or post the only possible option?

Then, after you know the issues at hand, do you risk traveling back? Or do you wait in the other parallel and help developed safer and more secure method?

Thoughts after turkey sedation.

Time Travel: Real or Fake? A Message to the Future

To All Time Travelers: Prove Me Wrong or Right

If time travel is real, I’d love to know. I’ve been thinking about how much I’d want to go back in time to stop some tragedies, warn people about COVID, or even grab those winning lottery numbers.

To any time travelers out there: if you’re real, look me up—Trisha Hill, Florida, whatever year. Tell me what happens to me. Do I ever get rich? Do I win the lottery? What happens to my family? Or, better yet, drop those lottery numbers and prove time travel is real.

I want to believe, but for now, I don’t know if it’s real or fake. I’m planning to dive deeper into this on a podcast episode, so let me know—what do you think about time travel? On this Thanksgiving, I can’t help but wish I could go back and rewrite some things, but maybe the future holds the answers.

Let’s talk about it. Will I be happy? Successful? Alone? Will my family thrive? Time travelers, if you’re out there, let me know.

Thoughts?

Food preservation using time travel

I know this sounds stupid, but if time travel is invented, and we send fresh food back to the past to an undislosed location or a capsule.

Is it possible to bring it back in its fresh state whenever its needed? Like, for the food its been in the past for only a millisecond. But in the distant future after it was cooked, it has been 1 hour and 30 minutes.

What would be the institutional implications of a time machine?

Say a working time machine was made by the public sector and overseen by the government (like the Manhattan Project).

Who would oversee it and make sure everyone was using it the right way?

Who would determine the "right way" to use it?

Would homeland security be involved or the F.B.I. to use it for an investigation.

How could anyone be trusted not to use the time machine for their own ends?

Such a powerful, godlike device in the hands of bureaucrats sounds like a freaking nightmare honestly.

I pray/beg every night to go back in time to prevent the decisions that have brought me to this horrible place.

If only I had listened to others.

If Time Travel gets invented.

Knowing the title of this, and I have my reasons as I'm working on an electrical/frequency approach to time travel,

I plan to travel back to December 12th, 2023 and warn myself about taking a crowed bus home, let alone keep my relationship with an ASMR-ist from being compromised, in exchange to give my past self the research.

What'll be your wish if time travel gets invented?

A list of every time travel show and movie since 1896

Over the past several months I have been compiling a list of every movie and TV show that features time travel in some form or another. So many Rip Van WinklesChristmas CarolsWonderful LivesConnecticut Yankees, and Groundhog Days. If a character changes years, acts on information from the future, relives the past, stops times, or generally plays havoc with the spacetime continuum, then it's on the list. You'll be surprised what things randomly decided to have a one-off time travel adventure out of nowhere.

This is a list of everything therefore: Spoilers and NSFW content included

Now I'm not claiming this to be the completed list, but at 6,000 entries I'd like to think I got the most of them. Whether all of them are still existant or 100% accurate is another problem entirely. I've worked off a very broad definition of what qualifies as time travel, so no doubt there will be a few that people will disagree with. If anyone knows of any that aren't here, I will start up a secondary list to be released once it has a significant number of entries to stand in its own right.

The full list can be found here: www.listchallenges.com/everything-time-travel-since-1896

How many of them have you seen? Which is your favourite? Which is the most surprising?

Any lesser known practical guidlines to time travel?

A tip i have always followed was to always carry a book detailing the architectural and geological history of the area your in. Make sure to never time travel whilst standing on a structural that does not exist in your target time, nor in the vicinity of a non-existant sturcture that will exist in your target time.

If your standing on the empire state building, do not travel to earlier than 1931. If you are in the bottom of the grand canyon, do not travel to before 1 million BCE.

Another tip is to not travel to times where your current area is suffering a natural disaster. Poor joe trying to find his misplaced flux capacitor, but accidentally time traveled directly into the center of a tornado.

Oh and, i would recommend not traveling in areas with lots of people. The result is quite... messy.
