Are we going about this in the wrong way?
I know there are species of plants in the Amazon, that can allow for people to Astral Project, their spirit can pass through the universe and enter dimensions that are so astonishing, they cant find the words because they don't exist to describe such an experience, maybe we are not meant to space travel physically but spiritually? Just an idea.
Astronomers have measured the galaxy’s diameter at 100,000 light years which means little until you appreciate that one light year equals 6 trillion miles, the distance a beam of light travels in one year. The fastest spacecraft ever built, the Helios probes, reached 157,000 mph (253,000 km/hr) as they zipped around the sun studying the solar wind from the mid-1970s to 1985. While that’s nine times faster than the International Space Station, it would still take 4,383 years to travel one light year at that phenomenal pace.
The Milky Way is a spiral galaxy with a prominent dense bar of stars across its core. The sun and planets are located with a spiral arm some 27,000 light years from the centre.
Even fleet light takes 100,000 years to cross from one side of the galaxy to the other. A light ray leaving Earth 100,000 years ago, when Neanderthals were the dominate human species in Europe, recently arrived there in our mobile-phone obsessed era. What will Earth look like 100,000 years from now?
