How can we send information backwards in time? Serious replies only

I can tell you how to send information to the future

Like even if our 4d space time is only some rulers and protactors of a higher dimensional plane it it still only going in one direction and that is change.
It doesn't matter if there are other dimensions surrounding us, we cannot see. If we move "forward", they will to - in some sense.

Because if you could, it would have already been done.

You could reconstruct the universe to exactly the way it was in the past but including the information

You put a laser somewhere in earth's orbit. Then you split the beam into 2 beams of entangled photons. One of the beams goes to a local object through a double slit without any measurements taken. The second beam goes towards your satellite in orbit of Mars. A computer controlled measuring device will either measure the polarization of the photons or not on arival. You let those go through a double slit as well. If you measure them on arival, the photons on earth side, which will hit the wall behind the double slit will form a particle pattern, if you don't they will form a wave pattern. This way you can send a single bit of information back through time from Mars to Earth. If you want to do it from Earth to earth, you need 2 lasers, one at Mars and one at earth, so you first measure the mars laser at earth and then the computer at mars will measure or not the laser coming from earth and this way you can send a bit back twice the amount of time light will take to travel from Earth to Mars.

You could beam it back to (You)re past, relatively speaking. But you'd still be in the relative future, so you wouldn't be there to see it.

If a black hole connects to a white hole in a universe where time moves backwards.

its theoretically possible; however its likely that all information that enters this system will be degraded/destroyed and it might take billions of years to pass.

Don't you think Cher would have done it, instead of making a gay song about it?

OP asked for sending information not humans

Find a way to encode data into the hawking radiation of a black hole.
The laws of physics go on vacation past the event horizon of a black hole and if higher gravity = slower time perhaps ~infinite gravity = negative time. If that's the case then the hawking radiation coming from a black hole could be from billions of years in the future.

Beta particles move backward in time. This can be used to send back information by organizing the particles into a data stream. They travel, like most particles, at the speed of light in a vacuum. So, you'll need to send them for the time needed to back. 1 year back, the data must travel 1 year. Also, you'll need a receiver. You cannot send back information to a point before the technology is created.

that's the "it" I was referring to.

No they don't you fucking neanderthal. Beta particles are Helium nuclei.

basically if you could travel backwards in time youd have to incept the idea into someone's head. the genesis for an alteration to a timeline would most likely require that the action that causes the change to occur from an inhabitant of that period of time. if you, the traveler, plants the idea and it deletes you from time, you get stuck in a loop. to stop that from happening you have to cause the shift and BEFORE the change occurs you need to travel back in time. that way you can see the ripple effect of changing history before it hits you, and if there are undesired effects you can push them back into line. this requires time travel and a docile, portable, supercomputer AI so its all larp for you guys

Time is the measure of movement, so in theory, you can't go back. However, in a multiverse system, merely travel across to a universe that's how ever many years behind that you want to go/send info to. But your current one, like all the others, can't be traveled backward and forward in. This scenario eliminates the grandfather paradox.

Travel faster than light, then travel to a point in space which is the same number of light-years away from earth as your age, use an OP telescope to look at earth, watch yourself be born, then think yourself in to your baby body and piss a message on the wall

mix ammonia with hydrogenperoxide. That should do the trick and open a time portal.

You can't, because I already did.
The first thing I did was making it impossible for others to do the same. Don't want others to interfere with my time manipulations.

since time is circular just live untill the end of time, and watch universe be reborn wait untill the specific timeframe go in and tell them all about it, then be imprisoned in asylum or burn at stake at your own convinience.

if you don't have that at home mix rubbing alcohol with chlorine bleach. Effect isn't as good but still OK.
You can also use vinegar if you don't have rubbing alcohol.
