Such examples can be given in different interpretations. For example, the sphericity of the Earth was known in the ancient world. Here is a reference: "The earliest theory about the Earth's sphericity was put forward in the 6th century BC in Greece. The philosopher Aristotle was a student of Plato. He gave three examples to prove the sphericity of the Earth: 1) the farther you go north, the higher Polaris is; 2) stars are visible in the south that are not visible in the north; constellations on the equator are high; 3) the shadow of the Earth falling on the Moon during a lunar eclipse is always round."
Even now, many people can't make scientific sense of his arguments. I will say more: even when it was technically possible to check it, when it was possible to improve the fleet to the appropriate level and realized a voyage proving it… not everyone believed it. What then, there are "unicums" even now. But the fact of proof became a fact not because of the fact that there were powerful ships compared to the ancient ones, but because they developed the science of navigation, invented appropriate instruments. So now we think that for flights into deep space we need, though improved, but still the same devices and technologies that we already have. However, something fundamentally new is needed. To give an example I can say that at that time, when they started to heat houses in cities with coal, they drew a picture of the future, where the elevator raises coal to the upper floors. And science-fiction writers, and not only them, outlined the future transportation problem as a problem of cleaning horse manure. Or for comparison we can take a vacuum cleaner and a broom: the function is the same, but the technological difference is fundamental....
The most important thing is that our mind ends up in distant worlds, not our body. The body is material, it will not fly above the speed of light.
Now let's think about the moral and spiritual side of the process.
Imagine, we have to take a child, he must have a connection with us, there must be a person he trusts unconditionally or with whom he is on very good friendly terms. There must be people whose advice and counsel the baby listens to. So imagine if that child there reveals the secret of the event that happened here, before the onset…
