Sure but that is still local. The speed of light means we can't have VR from a computer on Earth to a dude on Mars. If it takes 20 minutes for a command to be given and then 40 minutes go by between command and execution there will be no VR.
VR can only work if you are MILLISECONDS away from the computer.
That doesn't stop you from building a 'galactic encyclopedia' with radio waves or Lasers or gravity waves, neutrino beams, whatever we come up with in the next few hundred years and have receivers on distant stars, SOMETHING has to go to that star first and so far that journey will be max close to c and even if it's within one foot per hour away from c the trip, say its 1000 light years to that star, the spacecraft may THINK it only takes a few hours due to being so close to the speed of light but in reality OUR clocks say the trip took 1000 years and then the signal would have to have been being transmitted for 1000 years before the craft left so there would be any kind of signal when the receiver gets up and running and presumably retransmitting that received signal, which turns that device into what is called a transponder, which takes a received signal and retransmits it maybe on another frequency maybe at a different direction and so forth so after a few tens of thousands of years an operational galactic encyclopedia could theoretically be built but the problem there is it would still be 'local' in a cosmological sense. That signal say some of it leaks out of our galaxy, it won't be picked up by even the NEAREST galaxy for a couple million years. It would be difficult indeed for stuff like that technology to be built to work for millions of years and that signal would be very far down in the mud of other radio, IR, UV, gravity wave, neutrino stuff floating around the detection would be difficult indeed maybe requiring an antenna of billions of kilometers across to get sufficient gain.
But that would only be to allow some kind of comm between two 'close' galaxies, there are hundreds of billions of such galaxies, literally BILLIONS of light years apart, so any such signal even assuming detectors could detect such signals, said signals would not get there for billions of years. By THAT time our whole solar system could have turned into a red giant and Earth consumed in the atmosphere of that new red giant. And maybe the same with other main sequence stars in our galaxy.
You see the problem with all that galactic encyclopedia or VR kind of tech?
