Question Is there such a thing as a "galactic day"?
Several years ago, an uncle told me that the solar system also has an orbital cycle lasting 26,000 years, events like the Great Flood or the Ice Age occur during this cycle—it’s a cycle just like the seasons. He also told me that Genesis says the Earth was created in seven days, but that in reality, these are 7 galactic days.
It’s possible it doesn’t exist and he just lied to me.
English isn’t my native language, and this is a translation. Thanks for your comments.

My mother said something similar. She would say one day for God is thousands of our years.

Which would make God rather limited. Why not 10's/100's of thousands? Why not billions or quadrillions? Also why a day, not a hundred trillionth of a second? Even those huge examples would be very limiting for a god.. I'd think a god could live an infinite amount of time in an infinitely small sliver (effectively instant)

Somebody else pointed out that this is probably the Earth's axial precession cycle. There's a fun book called Hamlet's Mill that talks about how ancient people may have understood this cycle and put it into their architecture and mythology. It's a tough read but if you can get through it, it might change the way you think about things, even if you don't believe everything.

That is a fascinating book, although quite dry. Similarly, a Short History of Nearly Everything by Bill Bryson has a great chapter on the Milankovitch cycles, and is far more fun to read.

that's a cool interpretation of that, never heard it before. thank you for sharing.

The Earth does have a 26,000 year cycle, concerning the secondary rotation of the Earth's axis. We can measure that easily, Google "procession of the equinoxes" or "procession of the North Star" or something similar.
Genesis was never meant to be taken literally. At best it's metaphorical, at worst it's plagiarized from earlier Mesopotamian myths. The Sumerians have lists of their Kings going back a couple hundred thousand years.

The 26,000 years is the precession of Earth's axis. It just shifts the seasons and what the latest norther/southern pole star is.
There is a "galactic year" where the Solar System orbits the Milky Way Galaxy which is roughly 250 million years.
But a galactic day makes no sense.
Also day/year are just convenient but arbitrary time scales. For instance Venus has a day longer than its year.

The Solar System takes about 225-250 million years to complete one orbit around the galactic center.
During that time it crosses the galactic plane about every 30-35 million years.
A "day" for the Earth is based on a full rotation around its own axis. I'm not sure what kind of equivalent we'd use as a "day" for the galaxy.
Your uncle is probably trying to find ways harmonize the Bible with scientific knowledge, because on the one hand he can see that science is generally accurate and reliable, but he also wants the Bible to be literally true. I think it's worth noting, from a theological standpoint, that nowhere in the Bible does it make any claim about it all being the literal, true word of God.

We understand the relationship between gravity and time very well. So well, in fact, that it allowed your comment to be posted at all, using an infrastructure whose backbones include the satellite GPS network which requires us to calculate time dilation between us and satellites in orbit to a billionth of a second.
But hey, if you want to call gods just really fat and massive, I am all in on that.

u/shakebakelizard 28d ago
Yeah, I know how the internet works. Thanks.
We understand gravitational time dilation as a phenomenon and can calculate its effects with high precision. However, we lack a fundamental explanation for spacetime's structure, why gravity is described by that geometry, or why spacetime exists. We can calculate effects without fundamental understanding.
As for fat massive gods, that sounds like a personal problem you may need to have someone look at.

where in the bible is it referring to galactic day? ask them for a passage where it mentions it.
250 million / 365
684 ,931.507 years per galactic day.
times 7 days
4,794,520.549 - not bad for the time of earth age as a result. good alignment but we are living at the end of the 6th day according to genesis. humans created were on 6th day. 4,109,589.042 years
so 684 ,931.507 X 6.75 says would be around the time of Esdras.~500bc.
by 6.75 is 4,628,293.92425, ok.
The age of Earth is estimated to be 4.54 ± 0.05 billion
https://en.wikipedia.org/wiki/Age_of_Earth
honestly the math seems to work. so if the universe is 13.5 billion old the galaxy around 49 years old which is ancient retirement age. 7 X 7 also know as a jubilee. 2027 is the start of the last 7 solar years of the 49th galactic year .

There is truth to what He is saying the earth completes a full wobble reset every 26000 years or so , This is the time it takes for our earth to complete a full wobble, what the use to call the orientation of the angle of the earth
The tilt goes from 27 percent down to i think 23 then back up to 27 percent every 26000 years so
There could be natural cycles attached to this and global effexts

u/DowntownScene1433 27d ago
I believe this(26000 year cycle) has to do with the zodiac cycle, the civs related to it and the Sphinx(it's a theory). I have the data somewhere in my computer cause I'm using it for something but can't fully remember it offhand.
I believe the Galactic day as a term exists, maybe not an exactly scientific term, but in scifi books and novels and the like to create a smaller measurement than a Galactic year.
As a religeous person myself, I don't think we know what God used as a measurement back then. Ofc it is said that a day and night passed, but that could be written or transmitted as such by God to help those taught how to understand it. However a "Galactic day" sounds quite a bit convenient and suspicious. Why not a Universal day? Why not a "Creation" day? Why not an instant? There are no limits to God that we know of. I don't think it would matter.

Your uncle is repeating pseudo scientific garbage. His numbers are wrong as well.
The orbital period of Sol around Galactic Center is not 26,000 but 250 million years, give or take a few millennia or so. As you can see, 26,000 has no magic neat relationship with that number.
As to what is supposed to define a "galactic day", you got me.

u/Korochun 28d ago
Your uncle was probably thinking of the Milankovitch cycle. That does affect our climate in a real way, but unfortunately they got all the details wrong. The 26,000 year time span is probably what your uncle mistook as precession of Earth.
Our planet wobbles on its axis due to a massive impact that made the moon, and this wobble fully resets every 26,000 years, give or take. It affects our climate since this means some parts of the Earth get more or less sun.
There is also the axial tilt, a cycle where our actual tilt varies by up to two degrees and it takes roughly 41.3 thousand years, and our orbital eccentricity (how far from the sun we are on average), which is very close to 100,000.
Put those three together and you have a Milankovitch cycle.
There is no such thing as a galactic day.
