>>11410334
No

>>11410334
yes. But only forward.

is there any place in the universe where time does not move forward at all times?

Every sixty seconds, a minute passes.

>>11410404
inside event horizons

>>11410404
no, time is not a thing. Space-time is a thing and if time moves backwards, space would fold into itself in impossible ways. Faster than light travel and backwards time travel are the same thing and are made impossible by the same limits.

Yes but we will never be 100% sure.

I timetravelled in the future with my skateboard. I was literally faster than all the pedestrians!

>>11410334
Closed timelike curves are not inherently impossible, just very unlikely to actually exist.

>>11410334
Maybe. We know little.

>>11410409
>It’s impossible because uh I dunno

>>11410334
No because morality would then cease to function, nullifying God which cannot happen.

no, muh causality

>>11410334
Yes. However, you can only travel to the future, not the past.

>>11410334
If Time Travel is possible, we'd know by now.

>>11410530
Not this again. I'm not saying time travel is possible, but in case it involves wormholes for example it's not possible to travel to a time before the creation of the wormhole. So that kind of time travel would be totally compatible with there being zero time travelers in our time. Second, there's no reason to assume that anyone in possession of this technology would be interested in our time. It's also likely that if it's possible, it's also extremely costly and difficult. Appealing to the absence of time travelers, at best we can rule out relatively easy and inexpensive time travel being available in the near future to humans - if we are still similar enough in nature and interests it's safe to assume somebody would be interested in traveling to our time - then again the invention of time travel would realistically imply such radical technological development anyway that even that is still questionable. And only the type that allows traveling to a period before the technology was invented.

So you go in an event horizon and your life starts playing backwards?

>>11410334
If I said "yes" would you even believe me?

>>11410566
No you stupid cunt, a yes isn't even desired. Proof is.

>>11410567
Alright, so if I could prove it, hypothetically, what would you do with that information?

>>11410587
How?!

>>11410586
Christianity is bad. Humans are good. Rather, humans are the most awesome thing in all of reality.

>>11410541
Well said anon

>>11410591
The people of that time were desperately looking for a savior. By interjecting you would become that. Unless you mean...you wish to destroy it all.

>>11410587
I’d pretend to be Ares or something and convince them of it with a gun. Greek polytheism would have a new golden era afterwards

>>11410594
>Rather, humans are the most awesome thing in all of reality.
there ya go. good job reeling back from being retarded.

>>11410599
Well, there are a few methods to do this. One of them would destroy this universe. The others would land you somewhere else. Would you be willing to destroy us all?

>>11410601
You’re retarded. Humans are good beyond all else. We are practically gods.

Good has few things in its arsenal in this world. It can protect, preserve, and combine but it has never been able to create. This world seems to be adamant in it's entropy direction. Seems.

To destroy is evil.

>>11410637
>implying human history isn't the darkest cruelest fucking thing this earth has ever seen

It isn’t. The lives of the animals that lived before man are. Humans have always lived comparably gentle lives of farming and hunting with the comfort of beer, warm fires, and pussy awaiting them at home.

>implying there have been moar altruistic people than self-serving

There are and always have been more altruistic people than self-serving people. Humans are naturally emphatic thanks to mirror neurons.

>>11410648
>To destroy is evil.

Prove it. You can not.
Don’t shitpost.

>>11410645
Hell isn’t real, so there is no “road to hell” that could be paved. Try again.

>>11410652
When you destroy you take things away. When you have a glass of milk, it is good. When it's empty it is bad.

>>11410650
holy hell you're ignorant as fuck or trolling

>>11410656
>doesn't into metaphors

>>11410658
>When you destroy you take things away.

Prove “taking things away” is always evil. You can not prove any moral claims. It is impossible and you should know this. Don’t shitpost.

When you have a Nazi, rapist, serial killer, or environmentalist with all of their body fluids still contained within their body, it is bad. If you have a Nazi, rapist, serial killer, or environmentalist with all of their bodily fluids scattered around a room, it is good.

>>11410667
All I see is a greater form of evil. The big fish eats the little fish.

>>11410662
Metaphors are inherently deceptive and misleading, and as such should be avoided (unless you intend to deceive and mislead).

>>11410661
Holy hell you're ignorant as fuck or trolling.

Don’t worry, anon. One day you will leave the depressive phase you are currently in and realize the divine beauty of mankind. We walk with the royal bearing of Zeus; our muscles flex with the strength of Ares and the youthful vigor of Hermès, and our brains, without compare in the known universe, churn endlessly with the wisdom of Thoth. Truly, this world belongs to us.

>>11410671
>Metaphors are inherently deceptive and misleading
i disagree. i think they can be used to paint a picture and help people understand. but i'm probably mistaken and don't understand that people will perceive things in a way i dont want so you're probably right.

>>11410670
>All I see is a greater form of evil

Yes, you are the beta cuckold that would lay on the ground while Vikings raped his wife and burned his house down, because fighting them is “destructive” and thus evil. Until now, I did not believe that testosterone counts could be negative.

>>11410679
>Don’t worry, anon. One day you will leave the depressive phase you are currently in and realize the divine beauty of mankind
I recognize the obstacles of human nature present in all of us standing in the way of this beauty. You live in blissful ignorance which is fine. God has always forced the disgustingness of reality into my mind. It's k.
AND YA I'M USING GOD AS A METAPHOR FOR THE FORCES IN THIS UNIVERSE OF WHICH I DON'T UNDERTAND

>>11410683
I would fight. I would still be commiting destruction though. This is the "protect" part of good. Always remember: "Rope is cheaper than a funeral."

>>11410690
is that shit electrified or is that guy just being a retard on purpose

>>11410334

No.

Here is why.

>Let's say time travel is invented for real in the year 2800.
>The first time traveler travels back to see the crucifiction of Jesus.
>Now time traveling is invented and available.
>Just how many people will do the same now?
>Say the technology is widely available by the year 2850 and commonplace by 2950.
>How many time travellers would present be at every single major event in history?

>>11410695
You try running with microfilaments up the ass and tell me he is "being retarded"

>>11410690
>I would still be commiting destruction though.

So what? Everyone destroys and everyone creates. Neither are intrinsically “good” or “bad”.

> Always remember: "Rope is cheaper than a funeral."

Mass graves and incinerators are the just destinations of evildoers.

>>11410690
So what, we keep them alive then fucking what?

>>11410705
Sing kumbaya and watch My Little Pony

>>11410702
>everyone creates
See: >>11410632
Nothing has ever been created. Only the big bang was the last thing we saw come into being to be so massive that what we combine comes from it. It is the only thing "created" thus far. Sure you can come up with an idea, but even they are contrived from their environment. A combination of you and what is around you. This is a combination.

This. Why would you even want to continue being alive if nothing is ever actually created?!

>>11410769
>>11410765
This thread was originally about time travel, not ethics. I can afford to incinerate them as many times as I want. Then rivive them. Then incinerate them. Then rivive them again. With time travel at my command. Until they learn their lesson. When you can do such things, tell me, where's the hypocrisy now? There's none anymore. Only the lesson.

>>11410785
Y-You're either joking or you're pure evil.

convenient theory. could reality really be this clean?

>>11410404
Human brain. Whenever you recall a memory you're time traveling inside your head.

>>11411370

>>11410696
also if you say went back in time and shot hitler, your future self would not have the motivation to go back in time to do that, and cause a paradox, i do think their is alternate earths and if you could jump to them it wouldn't do shit.

>>11411433
I'm not completely sure if I understand what you're saying but if there are alternate timelines there's no reason to think there's any extra limitations to what you could do. All of the apparent "paradoxes" disappear in a very easy and obvious way if you just remind yourself that you didn't really travel to the past of your own world, you just arrived at a parallel universe that is currently in a state that it awfully similar to some past state of the universe you came from.

>>11410546
No, you get shredded into atoms and obliterated.

Why the fuck does this have more replies than my actual science thread? this sucks.

i do now that she pigged out

I wish there were some kind of time echo we could tap into, so I could look at ancient carthagian boobies without actually interfering with the past

Time doesn't exist b ut force does things have a nature so yeah but your body is not gonna allow it

>Time Travel (assuming to the past)
Well anon
Exceeding the speed of light is already out of the question taking into account the laws of physics so Tachyons and etc are out
Wormholes would collapse under their own gravity as soon as they form, and exotic matter to stabilize the wormhole isn't even confirmed to exist so I wouldn't rely on that
Cosmic Strings are not viable and would require too much energy to move the colossal galaxy sized crevices in the universe to near light speed to even get it in a position where time travel theoretically could work, and you'd need a ship capable of withstanding the journey among other things.
No time travel theories to the past are applicable to humans and even if they were we probably wouldn't be able to survive it or it would take too many resources to be practical.
Traveling into the future is more theoretically viable but even that would take too much energy (You'd have to move at near light speed)

>>11412148
>Exceeding the speed of light is already out of the question taking into account the laws of physics so Tachyons and etc are out
our laws of physics don't rule out tachyons, though there's no reason to think that they exist either - in that sense they're like wormholes. what they do rule out is accelerating normal (non-tachyonic matter) to or above light speed.

unless you think the possibility of "causality violations" rules tachyons out but then you could just as well dismiss time travel to the past without going to the detail you went.

>>11412164
Tachyonic particles by definition constantly move faster than the speed of light, but tachyonic fields with imaginary mass exist (like the higgs field). All im saying is that the existence of Tachyonic particles with imaginary mass and whose speed constantly exceeds c is not consistent with the laws of physics

>>11412199
>All im saying is that the existence of Tachyonic particles with imaginary mass and whose speed constantly exceeds c is not consistent with the laws of physics
The reason superluminal speed is normally impossible is because you need infinite energy to accelerate matter with normal mass to that speed. But that doesn't apply to tachyons because of their imaginary mass.

Yes OP, just rearrange matter to be arranged in the same way it was arranged previously. Look at deterministic initial conditions and end conditions and predict how the matter was arranged when time is reversed.

>>11412211
can't say I have a definite answer for that but I've heard that particles with imaginary mass, even though they check out mathematically, could not check out physically. Instead I've heard they're more seen as inconsistencies or instabilities and something to avoid within a theory. Looks like I have some studying to do lol

>>11410546
No, time would accelerate so that as you were drifting into the black hole, you could look back at the light following you in, and watch the lifetime of the universe flash by while tidal forces cause you to spaghettify into a thin beam of particles circling the drain into the singularity

>>11410340

>Nothing has ever been created

Wrong. Things are created daily.
