Almost exclusively day-ta.
I’m a day-ta scientist who grabs raw day-ta from a tay-ta warehouse (using an interface that makes it look like a day-ta base) and manipulates it inside day-ta frames in order to do day-ta analysis. I also design day-ta analytics schemas.
Sometimes, though rarely, that day-ta warehouse holds rah dah-ta, though, and I can’t tell you how it got there or why.
You should downgrade your certainty. By a lot.
The expansion is an expansion of space, and therefore explicitly increases the distance between galaxies. It does not, and cannot increase the speed at whoicj those galaxies travel through that space.
Right now, there are galaxies moving away from us at rates higher than the speed of light, a thing which is physically not possible if the expansion is due to an acceleration of the galaxies themselves.
You’ve misunderstood things completely backwards.
