Studying the Mandela Effect I have come to realize that humans may never be able to travel to the stars or even other Planets.
The Earth changed position in the Milky Way galaxy. We moved from the Sagittarius arm to the Orion arm. If Earth moved, if makes logical sense that every other Star moved also. The Effect could have hit every Galaxy. In fact, the entire Universe might have changed.
I keep saying believe your memory, not your computers but I was wrong. If your on a ship and you believe your memory over the computer you will in essence be going the wrong way. Away from your home Planet.
Humans may never space travel because if the Mandela effect is ongoing, and it appears it is, Stars locations in Space are constantly changing.
The Earth may be placed 80 thousand light years from its previous location. A fair distance to travel if you are not stocked up for the trip.
I have said it appears every person on the Planet is from a different previous dimension. In my old dimension, the picture of the farmer was with his wife and the Turkey leg painting did not exist. In this dimension Mars is much smaller than my old dimension.
If the Mandela Effect moves space, who knows where you will end up. You should actually trust your computer and not your own memory for your home Stars location.
I don't believe humans could build a ship stocked with enough supplies to traverse 80 thousand light years. Until we can, the question is not can we travel in space. The question becomes, can we get home?
