Could you counteract this by moving one second into the past and recalculate time and space...

but if you went back in time wouldn't you go back in space too?

Of course there is
There are many variables, but of course there is an absolute position of Earth
You just have to designate a point of reference and Earth's position is just a vector
Of course it has Jesus Christ, the universe expands radially

Absolutely not. The universe expands from everywhere. It is even common compare it with the surface of a balloon being inflated

>You just have to designate a point of reference
Yeah but that's no absolute position, it's relative by definition of "reference"

If our understanding of physics isn't completely incorrect time travel to the past is impossible and time travel is only possible relative to time as experienced by someone else.
So if you want time travel find a black hole or neutron star, stay close enough to not instantly die, wait a few hours to days depending on desired "time skip" and return to earth.

Newton suggested the orbits of the planets were circular.

Just move exactly one year at a time retard.

Exactly what he was asking... Relative to what? What is the "center" of the universe? It may take only 1 vector, but unless you have a truly static point as reference, you'll be flying blind.

You are only considering the position of the Earth relative to the Sun, but the Solar System itself moves around the center of our galaxy which, in turn, also moves. In other words, until what is know by science, there is no absolute position on universe.

Nigga just build a spaceship and fly back like how is this real lmao

The problem with this logic is that one second into the past, only considering the speed of the Earth moving around the Sun, would be way far from your time travel machine. If you consider also the velocity of the Sun around the center of the Milky Way and the velocity of the Milky Way around god knows what, you would die in space anyway.

This isn't how a time machine could work. It's definitely within the realm of possibility, but not like you think it is. Going back in time is really just reversing "entropy" and letting it play in reverse until you're where you want to be. Everything goes back, even you. Which means you stick to the planet like you always did. It also means you're younger, and it means you don't have any knowledge of the future since your brain is rolled back too.
Doing this isn't useful from within the universe. You'd need to step out of it to do meaningful work. Consider the universe as a flip book. Each page is a discrete state in this model (which I believe is the case, but being discrete isn't necessary for the analogy to work). Now this isn't a normal flip book, it's an algorithmic flip book. When you flip forward, a new frame is generated from the previous frame using some algorithm. When you flip back, the algorithm is reversed one step. Now, the things moving around in the page as frames progress end up getting really smart about their environment, they even start to guess at the algorithm which defines their existence! Clever indeed, but no matter what they do, they could never flip a page themselves. They're just images on a paper.

That's us. We're images on paper to whatever is containing our reality. There is no reason to believe there is nothing outside our universe, but we may never he able to comprehend what that outside is, nevermind trying to influence it. To us, "reversing entropy" is an absolutely futile task. We can't even compute a single frame forward or reverse completely due to Heisenberg's uncertainty principle.

Chances are it's a server rack in some five dimensional university campus.

There's no such thing as absolute position in the universe.

The initial location of the time machine

General relativity allows traveling back in time.

why the fuck is it a cube then

This picture implicitly assumes there is a preferred reference frame. I mean, time machines are also nonphysical so maybe the consistency in the joke is that it isn't supposed to make any sense.

The balloon metaphor compares the 2D surface of the balloon with the 3D space of the universe. If you choose a few points on the SURFACE of the balloon and inflate it, you can't say what point is in the center because every point is moving away from each other.

It's complicated. Read more about it here timecube.2enp.com/

>What is triangulation?

And sorry the grammar, it is quite hard to manage all the prepositions when you speak multiple languages. I know you probably doesn't understand how it is like.

Why did you post this?

Because i searched the original and thought to myself why not post it.
There is nothing to worry about.

Actually could be. Could be anything. Could be another higher dimensional universe and our universe is just something that happens naturally in it.

You were wrong. There is a lot to worry about.

Triangulation suffers from the same problem. The universe itself is growing - the points you chose will have moved themselves. If your points of reference move then they're useless as an objective measurement.
There's also the issue of velocity. Assuming you get the positioning correct, you also need to adjust the velocity of the person so that they're not instantaneously obliterated by the Earth.
Plus the fact every calculation has to be done at a universal scale pretty much guarantees that even the smallest margin or error will result in death - and there will be a margin of error unless you're dealing with perfect data... which doesn't exist

Please tell me.

No, but you could counteract it by not being a fucking retard.

It isn't.

based schizoposter

You make a fundamental mistake. You assume that the time machine imparts on the object some kind of property that causes said object to travel forward in time. That's not how time travel works.
In reality, a time machine would create a wormhole between itself in the present and itself in the future, through which you travel, so you would always appears at the same exact place relative to the time machine, with the same exact relative momentum.

What's your point? Sure we can calculate with reasonable certainty where any celestial body will be at some point in the future, given some observation of its current trajectory and expansion of the universe. That still only leaves you able to calculate some point relative to yourself, not find some absolute coordinate system.
