Warning: This Carl Sagan explaination has caused existential crises.
He explains how 5th dimensional beings perceive 3D creatures, and the implications are so disturbing, I paused it three times.
He said:
A being from the 5th dimension could reach into your locked house, take an object off your kitchen table, and place it in orbit around Jupiter without ever crossing a wall, a door, or the vacuum of space.
People ridiculed when Carl Sagan said this.
But, he was walking through the cleanest piece of geometric logic in modern physics, and most people who watched it never realized what he actually gave them.
The demonstration starts small.
Imagine a flat creature living on a sheet of paper. Its entire universe is length and width. It has no concept of "up" because up doesn't exist in its world. The direction is literally unthinkable to its nervous system.
Now take a three-dimensional apple and push it slowly through the paper.
What does the flat creature see?
A dot appears from nowhere. The dot expands into a circle. The circle grows, shrinks, then collapses back into nothing. The apple was always whole. The flatlander only ever perceived cross-sections of something its dimensions could not contain.
That's the entire trick.
Sagan's move was to rotate the analogy upward and let you feel the vertigo yourself.
You are the flatlander. Your body, your brain, your sensory apparatus evolved to process three spatial dimensions and one directional slice of time.
Anything existing in a higher dimension would pass through your world the same way that apple passed through the paper. As fragments, apparitions, sudden appearances, inexplicable disappearances.
A 4D being could see every organ in your body simultaneously from the outside, the way you can see every room of a dollhouse at once from above.
A 5D being could observe your entire lifetime from every version of you from infant to corpse like a single unmoving sculpture stretched across time.
What's interesting is it's a direct consequence of how dimensions mathematically nest inside one another.
Every dimension has full access to the interior of the one below it. A 3D hand can touch any point inside a 2D square without crossing its edges. A 4D hand could touch any point inside your sealed body without breaking your skin.
Sagan has really handed us a quiet reframe of every "impossible" phenomenon humans have reported for thousands of years like visions, presences, objects moving through walls, beings that seem to know your past and future.
Though his Geometry doesn't confirm any of it. But it removes the argument that such things would violate physics.
Life is fucking electric bro. Don’t fall for the doomer shit. Thats for losers and normies scared of their own shadows. Walk around like God sent you and smile at everyone you see. Spread light and abundance. Build things and take chances. This is the best time in history!
Earth is just one of about 100 billion planets in our galaxy, which is just one of about two trillion galaxies in the universe. And our lifetimes are only about 1/3,000 of humanity's existence, which itself is only 1/20,000 of the Earth's existence.
In other words, we are unbelievably tiny and short-lived and no matter what we accomplish, our impact will be insignificant.
At the same time, we instinctually want to matter and to evolve, and we can matter a tiny bit--and it's all those tiny bits that add up to drive the evolution of the universe. #principleoftheday
I’m a retired brain surgeon and I wanna tell you why you feel like life is passing by. I just need one minute to explain this to you so hang in there.
Repetitive daily routines stop the brain from recording clear detailed memories. When every day looks the same, your brain does not track time the same as a clock does. It tracks change. If nothing new happens then days, months, and years start to blur together.
This is know as Time compression. When life lacks variety, your brain compresses past days together, making it feel like time is sped up.
To stop feeling like life is passing you by, add new experiences to your life. Break routine habits, like changing your daily home routine, taking a different route to work, or trying a new hobby.
Schedule small trips or plan new adventures so your days do not blend together.
Practice mindfulness by staying fully focused on what you are doing right now and not trying to race off to the next task.
Keep a journal and write down happy memories or memorable parts of the day before you go to sleep.
Take deep, calm breaths when you feel anxious or rushed to return your focus to the moment.
You can and you will retrain your brain to not feel like life is passing you by by following these few simple measures.
No animal on earth knows what a Monday is.
No plant. No ocean. No nervous system in nature. The week doesn’t exist. You’ve been exhausted by something that was never real.
Where can the three of us build a rooted, sunny, nature-rich life with enough distance from family pressures, strong schooling and community, and enough professional freedom to feel safe?
The goal is not to escape ordinary life.
The goal is to build an ordinary life you don't need to escape from.
Travel then becomes spice rather than medicine
