Time is a construct. It is linear, it is psychological. Psychology can be manipulated so yes man's perception of time can be also. Ever been in an isolation room with the lights out. Zero sound outside of what you make. It is eeeerie.
Our microtubules which house our memories and thoughts do much the same thing, they can travel backwards and forwards in time to tell us to react to danger.
An example: Tennis balls travel faster than the time it takes to react to them, as measured by brain electrical stimuli. But the players manage to hit them and return them to somewhere beyond the reach of their opponent. We know about the incoming ball before we perceive it. And as for table tennis?
Agreed, The way i see it, time is simply the movement of atoms changing from one state to the next. A time machine would need to control EVERY SINGLE Atom in the universe and reverse them into a previous state, which would make time travel completely pointless. With that machine, you could simply just change the universe into any state you wanted, you would be God.
it's impossible, and will remain impossible forever. If it were possible, it would already exist and would have always existed
Or
the best we can do is create a snapshot to return to. If Time Travel ever gets invented, it would only be possible to travel back to the point in which it was invented, impossible to travel further back.
I do not believe it's possible to time travel back to the Dinosaur ages, for instance. Even time travel back to ww1 and ww2 seems impossible, unless the tech has existed and been hidden from us for hundreds, if not thousands, of years
I’m just curious, I don’t have extensive knowledge on this or anything, but.
Wouldn’t this assume humans are the only entities in the universe? It’s possible we haven’t discovered time travel, but that doesn’t necessarily mean it is impossible, and also doesn’t mean some other entity didn’t “have it” for a while now.
End of the day, I think it’s just a fun thought experiment. The other possibility is combining time travel with the concept of infinite universes. Every instance of time travel wouldn’t go back to the original timeline, but would bring you back to a specific point while creating a new timeline. Then it gets interesting, if you can’t travel between parallel universes time travel effectively is “useless”.
Idk why I even typed this all up, thinking about this kinda stuff always was super interesting, feels like I spin myself in circles everytime I think about it haha.
Humans having the technology is irrelevant. Either it's possible, and always has been possible and has always existed, or is impossible, and will always be, and will never exist.
I mean, if time travel doesn't exist in this exact moment, then how could a future traveler get to this point in time? If a future traveler could travel back to now, then time travel must exist now and must be possible now, in order for the traveler to exist in the now.
If it ever gets to a point where it exists, either it exists in a way where it always exists and can travel back to anytime, or it would have to be a specific snapshot that we could return to.
I'm just theorizing how it could work, regardless of who controls it
Put simply: where would the knowledge of the tech to time travel come from? It can't come from someone in the future, that would cause a paradox. The knowledge has to hava some source at some specific point in time. And then travel before that specific point in time would be impossible.
If someone "invents" time travel in 2037, and uses the tech to travel to 2025 and someone from 2025 sees and and learns about it, then the knowledge only existed from the knowledge already existing.... who is the patient zero of that knowledge? If the traveler from 2037 could go back to 2025, then the tech has to exist in 2025 to receive the traveler.
The comments here are much more interesting than the linked article. It really says nothing other than a scientist said he’s done it. No details, no explanation.
The Earth is spinning around it's axis, while spinning around the sun. 5 minutes ago, you weren't just in another time, but in another place.
Even if you could calculate exactly where to be, you then have to instantaneously transport yourself there at exactly the right moment.
Not to mention, what if you were on the fourth floor of a building that didn't exist in the time you traveled to? Any excavation on the site could leave you high above the ground or buried underneath it, or you could end up inside a brick wall. How do you realistically figure out exactly where to materialize in the past?
You'd realistically have to use at least an aircraft if not a spacecraft and transport the whole shebang into the past with you inside somewhere safe and then travel to the place you want to be.

🎵 Let's go surfin' now
Everybody's learnin' how
Come on and safari with me 🎵
This is not true. Sounds neat but no, there is no time travel.
People struggle to give up the fantasy. It's fun to think about.
"Sounds neat but no, there is no time travel."
Lots of denial on this thread. I guess everyone is a theoretical quantum physicist.
Theoretical quantum physicist. Emphasis on theoretical. Meaning there is zero proof. Don't need a degree to understand that.

I have two potential thoughts on time travel:
I do not believe it's possible to time travel back to the Dinosaur ages, for instance. Even time travel back to ww1 and ww2 seems impossible, unless the tech has existed and been hidden from us for hundreds, if not thousands, of years

so it isn't fun at all?

Here's my problem with time travel.

like ALICE goes through the project looking glass. Wonderland.
I read this thread yesterday😀
Why yes I have used a mirror to travel in time, funny you should mention it!
