Here is a paradox - if you went back in time, found Anne Frank's diary and threw it out before anyone else could discover it, what would happen to In the Aeroplane Over the Sea? Would it still exist? Find out in my new show, Time Jerks, starring Tracy Morgan and Jimmy O. Yang!

ClamdestineBoyster posted:I think physical, biological time travel could be possible as a Boolean expression, so that the information and consciousness could exist in the past, but it would lack potency and tangibility. In other words, it couldn’t effect the future in any way. If you built a functioning time machine today, you could only travel back to today from now on. You would essentially just be a ghost. If you wanted to interact with anyone you would need people who have partially suspended free will and have agreed to act robotically as to not effect causality, a covenant to fulfill a destiny. So you would know if you came up in a spectrum of privileged knowledge from the future, that you would robotically time travel back in time in your own future and speak a program to your coven who would make sure you fulfill your destiny by word. It is correct that certain time machines in general relativity, such as wormholes, could never send someone back in time to before the exit of the wormhole existed, though i'm not fully convinced these things haven't just been totally misinterpreted by would-be sci-fi authors and no time travel is actually possible if you examine the maths correctly. There is the misunderstood concept of "closed timelike curves" which people tend to see like either Groundhog Day, or "you back in time and gently caress your grandma", but those things both involve discontinuities, like "time resets", or "someone from the future suddenly appears in the past then goes away". There can be no discontinuities in general relativity; space-time must be smooth. A closed timelike curve never goes back in time, instead you can't say which events are in the future of an object on such a path and which are in the past. They're both.

Time travel is real. I know because I was part of Obama's unit. Unbeknownst to us, Lowtax sabotaged the project with the goal of making the perfect goon. I became unmoored (see what I did there?) in history and had to bang my way through until I succeeded. I met a woman named Marianne and after we did the nasty in the pasty I must have completed Lowtax's mission because I suddenly found myself back on Mars.

We'll never have even flying loving cars because of the ridiculous amount of energy and greenhouse gases produced that would be involved in getting millions of them airborne and staying up there. Not to mention the inevitable too-frequent airborne collisions that would regularly rain down cars, human bodies, and pieces thereof onto those below.

Well, not exactly but it was used in an example. It was very cringe and very high school but there is nothing really "free" about having to travel in a straight line, even if you can branch paths along that line. We perceive time as linear but do we really have a good reason to believe it is?

Why is physics so heavily enriched for creeps? You'd think it would be evenly spread across the sciences but it isn't. Obviously engineers of all stripes are their own breed but I'm talking about real scientists. You'll have the occasional "had sex with a grad student" scandal that happens anywhere there is a power differential but physics as a field is just a lament configuration of eyes wide shut parties.

And if one or two nerd professors stared at their equations too long and manufactured what purported to be proofs that it is somehow possible, you can bet that ten thousand other nerd professors disproved their proofs. What I mean is, some people say you might build a wormhole that goes back in time to tuesday. But time would still pass for the other end of the hole; if you enter it tomorrow, you would instead go back to wednesday. No one ever mentions this, or the implications thereof. Some others say you create a time displaced wormhole by putting one end in a rocket and travel at relativistic speeds so that a clock at one end would have measured a lot less time than a clock at the other. Supposedly then by entering it you end up back in time. But it isn't clear how this would work as GR does not permit discontinuities; at some point in the wormhole, the rate of your clock and the rate of a clock on the rocket must match up. The whole idea of there being a "different time" you could end up in also seems dodgy. Everyone's talking about this and that sci-fi paradox when there are unaddressed issues at the most basic levels. But the maths are complicated and I don't currently have the time to go through them properly. If you're worried about being scrambled eggs, "you" in these examples can be considered a sequence of radio signals or a single particle.

Okay, so like consider two points in a gravity field; one on the surface of the planet and one higher up, and the difference is such that due to gravitational time dilation, a clock on the surface ticks half as fast as one at the higher point. Now park one end of a wormhole at the surface clock and the other at the space clock. According to internet wisdom this creates a time machine as one end of the hole will "lag" behind the other. But consider instead what you see if you look at the space clock through the wormhole compared to what you see if you look at it through a telescope. There are two basic possibilities: either you see the space clock tick at the same rate as your clock, or you see it tick at the same rate as when you look through the telescope. In the first case, spacetime inside the hole must be flat. But then consider what that means for space around the mouth of the hole. It must be of such geometry that clocks there and on the surface tick at the same rate. Unless we have a discontinuity, that end would itself be a source of gravity in the space around it that you would have to climb out of when trying to get away from the hole. As such, when looking at a clock near the end of the hole through the telescope, you would see it tick at a different rate than one in "free space" and the light from it would need to travel through some complicated geometry to get to you. Any attempt of time travel would be prevented by climbing out of the gravity well around the hole. In the second case it is trivial: the curvature from the planet travels through the hole, and the geometry around the end of the hole would be the same as that of space around it. Travelling through the hole would be exactly the same as leaving the planet normally and require the same amount of energy, and time travel would not be anymore possible than with a regular rocket. These answers would also prevent using wormholes as perpetual motion machines; ie throwing a ball through the lower end of the hole and absorbing the kinetic energy it gains through falling back the long way through the gravity field. This is not too surprising as energy and time are often considered intrinsically linked by symmetries and conservation laws. Now if it turns out gravitational time dilation can't actually be used to create a time machine in this way, it is highly likely the same will turn out to be the case for relativistic time dilation. But good luck trying to find anyone talking about that, compared to shooting this or that person.

Wormholes are inherently unstable due to destructive feedback. Travel to the future is possible with black hole mechanics but energy inefficient. Simpler and better efficiency to build an allmind data collector matrioshka brain and sim out unreal realities. If you want time travel from a singularity the technological singularity is the shining path. All paths lead to the Basilisk.
