I am looking for something that would contain everything that we know and have connected topics so I would need only one source instead of 20. I am realising that if there would be something like this I would probably know about it but I am testing my luck ... it could only contain data till technical revolution in England or similar date because closer to the present the amount of data rises exponentialy and it may not be possible to write it all down. It could be book but I would be more glad for some online source, thanks.
Hello! Unfortunately, there is nothing like what you seek. There is simply too much knowledge, too many different understandings, and too much information to contain in one place. The closest you might get is wikipedia, which has its obvious drawbacks.
