The actual chronovisor is a gnostic machine, it needs gnostic souls to work. Other machines are just fantasies. Man does not have the technology to build one.
The Cosmic Microwave Background (CMB) is a broad band of electromagnetic frequencies ranging from 0.3 Gigahertz upto 630 Gigahertz, that emanated from "The Big Bang", which created our Universe...You would need to "tune into" the specific electro masgnetic frequencies that for example, came from when Jesus was crucified....Sooner you than me! ..Hello everyone! In addition, we have a lot of acoustic noise from everything(not only waves from past). Residual radiation of neutrino or something is a small part of much things. Also, we should find a way, how to amplify the signal. Do you have an idea, how to make it?
