How do you describe Earth's Universal Coordinates

Mathematics is the universal language. How using only mathematics could we describe where we are in the universe, or the galaxy using math?

I'm saying in the movie Contact the aliens sent us mathematic blueprints for a space rocket and directions where to find them. What coordinate system for the universe or galaxy is known.

Maybe there are different directions....
Aliens from Alpha Centauri go to 5,34,6,-3,.2
Aliens from the center of the Milky Way go to 10,374,485,-84,38,6
Aliens from the Andromeda Galaxy travel to 3847,475,489,-488,-484,.44 to get to the center of the Milky Way and get directions from there,

But really I'd like to send out a signal to aliens that I would understand to be able to navigate to Earth...

Is there one?

I only know Algebra II and Geometry

We have NO clue where the universe starts or ends..no clue what is beyond that and beyond that, real math requires a standard starting point of reference, and a guage to measure it by. Hologram, multidimentional, layered, superimposed, does not matter. If you use earth for these points, and know where it starts and ends, that is one thing, but math will only get speculation that cannot be varified at our current rate of knowledge.....I have no clue...

Yes.

While centered on Earth, it could just as well use the center of the Galaxy.

Universal coordinates:

Done and Did already

The little * looking thing in the lower left?
Well, that's our distance from some several noticeable signpost landmarks like pulsars that can be used to triangulate on our position.

Since there is no reference point or origin, we would not be able to provide co-ordinates for those lovely extraterrestrials. However, if we were to go all Star Trek and explore the universe, we would use a 3-quasar reference to navigate. Since the universe is 3-dimensional (discounting the quantum mumbo-jumbo), we would require 3 points of reference, as opposed to only requiring 2 points of reference for exploring via the oceans during pioneer days (sailing atop waves is only 2-dimensional).

Earth in reference to the 3 quasars would be the "origin", and we would calculate the angles and brightness of quasars in relation to the ship we are traversing in as reference during galactic travel.

Sure it's its simple....

Earth is right around the corner from west hell, two blocks from south # and the perfect jail cell.

So I stole that post and made a morse coder message of it:

PLEEeeassee DO NOT tell them where we are................

LONDON — British physicist Stephen Hawking says aliens are out there, but it could be too dangerous for humans to interact with extraterrestrial life.
Hawking claims in a new documentary titled "Into the Universe With Stephen Hawking" that intelligent alien life forms almost certainly exist — but warns that communicating with them could be "too risky."
"We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet," Hawking said. "I imagine they might exist in massive ships ... having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.”
The 68-year-old scientist said a visit by extraterrestrials to Earth might well be like Christopher Columbus arriving in the Americas, "which didn't turn out very well for the Native Americans."

I would have to agree with Phage on this point.
It would not only be logical,but easy to use Earth as a point of reference.
Our Sun may be a better choice, but that is subjective.
Speaking of our Sun, for hoots and giggles, lets input our Sun
into the equation as reference point 2. Now you can have fun and
pick any other Celestial Body as your input #3.
For posterity, choose any other heavenly body above or below
your current imaginary plane as input #5.

You could add a 6th sense input as well. For Classified reasons.
Now add time and trajectory for all current inputs.
Then take a "snapshot".
That result should place you somewhere in The Universe.

That is all I have to say about that. S&F

I thought just laying there seeing myself as the sun looking Beyound the sun!

Saturn is my controlling Planet thats is!

The Rings have me Spellbound!

You would need a common datum. I have my doubts two different planets, unknown to each other, would share such a thing.

Someone mentioned pulsars and triangulation. Possibly, polar plot. Again, common grid would expedite those calculations.

Totally feasible I just do not think it currently exists.

Nevermind

Maybe there are different directions....
Aliens from Alpha Centauri go to 5,34,6,-3,.2
Aliens from the center of the Milky Way go to 10,374,485,-84,38,6
Aliens from the Andromeda Galaxy travel to 3847,475,489,-488,-484,.44 to get to the center of the Milky Way and get directions from there,

... so ... the aliens have read Descartes and
understand Cartesian coordinates. Hmmmm.

Even using constellations would have to be
rigged from the vantage point of the person
the information it was sent too.

Also time is a critical component, so even
if coordinates are used, they would probably
be fourth dimensional, at least.

I assumed that the "settings" of the "machine"
were specified in the alien blueprints.

Would love to have been in the room when
S. R. Hadden reverse engineered those bits.

It is odd that our solar system's plane isn't lined up with the galactic plane...

www.space.com...

Besides it takes a minimum of 6 variables to define just an orbit,
in a Cartesian system. This doesn't include precession of the Axis,
precession of the Perihelion, or how far above or below the
galactic plane the solar system in question is. The Earth and it's
Solar system currently being above the plane, but soon to start
heading below it.

Correct!

@How do you describe Earth's Universal Coordinates

Dimension-Galaxy-Nebula-Universe element count number=
total elements material present within dimension-galaxy-nebula-universe
Planet element count number=
total elements material present within planet
Species count number=
total past and current species counted present within planet
Nearest STAR material make up number=
total elements material present within STAR

coordinates =
Dimension-Galaxy-Nebula-Universe element count number.Planet element count number.Species count number.Nearest STAR material make up number
coordinates =XXXXX.XXXXX.XXXXX.XXXXX

This OP would be a way to locate with unique signature per location of interest...

How could there be any possible 'map', or other attempt at referencing Terra without also lookng at time?

Would it perhaps be something like, go 13.798±0.037 billion years post the big bang, and cruise along the equatorial symmetry plane of the Milky Way for about 14 light years? If you can see the Scutum Crux Arm of the Galaxy hang a hard left, because you've overshot the central Galactic Freeway for
Earthlings. These are segregated stellar freeways - always keep your i-passport on your person, as the last thing you want to encounter is a pissed off racist Rigellian with super-laser technology made with ground up slave labour more or less digested through the paradoxical Large Quasar Group and then filtered through the Himiko Cloud.

Be very careful if you find yourself anywhere near the Virgo Supercluster as this is an extremely bad neighborhood, with a rumoured Black Hole somewhere in the vicinity give or take a few hundred light years. Several interstellar hitchhikers have gone missing near this Supercluster, never to be seen again.

How we have described our location on things like the the Pioneer probe plaques, the covers of the Voyager probe golden records which left the solar system and in interstellar radio messages is by using the position and spin of a series of stars called pulsars, which emit a steady "ticking" and measuring of a distance from each of them. This ticking is like a signature, or fingerprint. Each pulsar's is slightly different.

If someone were too look at how far the Sun and our Earth is from any three of these referenced pulsars then they could triangulate the location of our solar system anywhere in the galaxy and perhaps beyond it.

Not only would the pulsars etched into the record cover and plaque tell an alien WHERE we came from but WHEN the message was sent since these pulsars move and slow down over time while maintaining their unique fingerprint.

So you can tell them where we are by using pulsars and they'd know when you sent the message as well.

The Pioneer 10 Plaque - The radiating lines to the left represent different pulsars, their unique ticking and their distance from us (we are in the center) of all the converging lines.




Voyager Golden Record cover: Note how a similar diagram of our location using pulsar positions is in the lower left of it.



The thing to remember is that any human derived co-ordinate system is irrelevant from an alien perspective.

That is why we turned to nature which was nice enough to provide us with these landmarks which any intelligent species in the universe would learn about fairly early in their exploration of it.

The point of the OP was to provide a means for those of the alien persuasion to locate Earth. Since, as pointed out in the OP, the aliens in Contact were able to designate a location in space(time) to humans (as backward as we surely are), humans should be able to convey our location to aliens (as advanced as they may be).

A simple coding problem with a variety of solutions.
