I got interested in this too, especially when science tells us that solid objects are atoms and that is like 99.999% empty space so it's basically holographic. Our brain just interprets reality and even solidity, much like is said in the Matrix movie. Many researchers, authors have done a lot of research on it and so the theory holds weight. Elon Musk like says things like it is unlikely we are even in base reality, and that there are many parallel realities. It also could be some deception or truth mixed with lies so people will just believe whatever variation most pushed of what's becoming a more mainstream topic now, but I don't know. CERN and the D-Wave computers are some crazy stuff too, and they are doing some weird ritualistic stuff there. They obviously know a lot more about this, quantum entanglement and so on than they will tell. A detailed CIA FOIA document also mentions the holographic nature of reality and time travel. Whether that backs it up or discredits the theory is for anyone to decide.
