What would be the least impactful way of using time travel?

JonsJava@lemmy.world to Ask Lemmy@lemmy.world – 78 points –

Started as a shower thought (literally in the shower), but decided to make it more open-ended.

My answer to this would be "watch future seasons of anime that I am waiting on".

I don't see how that could cause a huge ripple through time.

Going massive events that are either completely void of people or full of people.

Star exploding? No one around, nothing to change.

Parade for the astronauts coming back from the moon?

What's another guy standing around, just minding my own business.

Until everybody throughout time, after the machine has been invented I gues, also wants to experience the same parade 🙃….. I mean not until…. It’ll just happen ?….. now my head hurts

Long, but relevant Douglas Adams quote:

One of the major problems encountered in time travel is not that of becoming your own father or mother. There is no problem in becoming your own father or mother that a broad-minded and well-adjusted family can't cope with. There is no problem with changing the course of history—the course of history does not change because it all fits together like a jigsaw. All the important changes have happened before the things they were supposed to change and it all sorts itself out in the end.

The major problem is simply one of grammar, and the main work to consult in this matter is Dr. Dan Streetmentioner's Time Traveler's Handbook of 1001 Tense Formations. It will tell you, for instance, how to describe something that was about to happen to you in the past before you avoided it by time-jumping forward two days in order to avoid it. The event will be described differently according to whether you are talking about it from the standpoint of your own natural time, from a time in the further future, or a time in the further past and is further complicated by the possibility of conducting conversations while you are actually traveling from one time to another with the intention of becoming your own mother or father.

Most readers get as far as the Future Semiconditionally Modified Subinverted Plagal Past Subjunctive Intentional before giving up; and in fact in later editions of the book all pages beyond this point have been left blank to save on printing costs.

The Hitchhiker's Guide to the Galaxy skips lightly over this tangle of academic abstraction, pausing only to note that the term "Future Perfect" has been abandoned since it was discovered not to be.

There's a 'theory' the Titanic really sunk under the weight of time travellers going to watch the sinking firsthand
