Time is a construct that humans created to better understand our reality. Its a ruler, nothing more, nothing less.

A guide to time travel.
This community is serious; not intended for fan fiction or parody.
What we normally think of as time travel isn't yet possible, but discussions of the physics, rules, constants, and possibilities will be productive as we work out ways to make time travel a reality.
Discussions of science fiction, imaginings, myths, and hoaxes are not productive and don't belong here.
This community is dedicated to the pursuit of time travel as a science, not chasing down myths and hoaxes. Please constrain your posts to the realm of physics, mathematics, ethics, practicality, and related subjects.

You're saying entropy doesn't exist?
Or that your subjective delusions of what can be objectively measured is the same as my subjective delusions? Then how are they subjective and not objective?
The whole "brain in a vat" thing is so old.
Hmm wonder why a black hole warps space and time then. I guess you could say we gave it the thing a name.
That’s philosophically true, but mathematically, time is also an objective interval that exists regardless of our perspective. That interval doesn’t need humans to exist.
Time passes whether humans exist or not. All animals exist in time, and a consciousness is not required. Are you suggesting time didn’t exist when nothing but bacteria existed?
Time is an interval of spacetime, whether we exist to perceive it or not.
Math is another human invention, another ruler. It is the mind that experiences time, time is experienced differently based on many different inputs. Which doesn’t negate its usefulness, but it was invented by a literal Ape, with serious limitations, we have so much to learn.
It’s not. Maths is an objective measure of the world, and time exists beyond us. We define these things in our language, but they don’t need us. We didn’t create these things, we only describe them.
Yes, but from the eye of the observer.
THE EYE
Seriously though, it isn’t just a construct. Mathematics is how we define constructs.
👌🏻
Let me be clear, I believe everything we experience is illusory, all built atop the quantum universe. This next part gets a bit cray, we are all of one and the same, the underlying energy that feeds us endlessly. It’s the only way to fully explain absolutely everything. I do believe in science as well, but I also realize we’re just a bunch of monkeys flying around through the cosmos on this rock.
When I was only 2 years old I had an awakening experience that forever changed me, and I had this realization of what we are. Like full on holy-shit moment, and over my lifetime I’ve had several out-of-body experiences and have been able to validate the experiences with the help of others.
In 4th grade, I was in the lunch line which was outside going between 2 brick walls, and like a 4th grade moron made myself pass out, hit my head on the wall and passed out. During which time I was out of body like 50 feet away and could see myself laying on the ground, I could see in every direction all at the same time with a limit of focus on a direction, I could see the other kids playing, everything. When I snapped out of it and got up, I looked around freaked out a bit, then proceeded to my classroom and when I got past the building which was one of the walls I could see the playground, and thats when it hit me, the exact kid I saw on the swing was still swinging. Another group was playing dodge-ball. I mean it was all there, and the kid that I walked to get lunch with told me I was on the ground for like 2 minutes.
Anyways, sorry for the rant, but it was just an interesting experience that made me question reality.
Let me be clear, I believe everything we experience is illusory
Not bad. But explain a thought, whats involved in you being aware of any external stimuli. Electrical and chemical interactions.
yes and those are physical things in the real world, not illusions
This next part gets a bit cray, we are all of one and the same, the underlying energy that feeds us endlessly.
Ah, um…this is meant to be a sub talking about science, not metaphysics or religion.
I appreciate your personal story. Really, I do.
But that has no bearing whatsoever on a practical, repeatable method of time travel, right?
