When astronomers look at the distribution of galaxies on scales of billions of light-years they find that they are not evenly distributed. This detailed simulation of large scale structure was created as part of the Illustris simulation. The distribution of dark matter is shown in blue and the gas distribution in orange
The 'dark matter' looks like filaments.

Why not? Beginning and end, just like time are things we have invented to try and makes sense of our world, simply because we can't understand it otherwise. But doesn't mean these things have to exist.

We didn't invent time.

We did, however, invent the measure of time.

Why is a second the duration that it is. Why are there 60 seconds in a minute? why 60 minutes in an hour? Why 24 hours in a day?

Who decided how long a second should be and why did they decide this? Is it because they knew where/when it started and ended?

We've also changed it, it used to be a percentage of a solar day now it's "the duration of 9192631770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom."

My only assertion was that time is not invented.

To answer the questions.

It is the duration it is because of our calendar they, then tied it to an atomic reaction because then anyone (with equipment) can recreate and get a precise measurement of a second. There are 60 minutes in an hour because of the use of a sexagesimal counting system when humans first started noting time and it's passage into night and day. The Egyptians are responsible for the 24 hour day, i'm not sure what competing theory is correct on why though.

It was decided by priests probably when they started subdividing everything, i'm not sure. The International committee for weights and measures defined the new second in 1967 to caesium decay. They decided this because anyone with equipment could measure a precise and accurate second.

Finding a way to measure something is not the invention of it, maybe the discovery but not invention.

Is there 'nothing' north of the north pole?

You could say, if you keep going north, you can go past the north pole, but what you get is not 'more north',.. but it's not 'nothing' either.

This questions what 'north' means in the first place, and the meaning of the original question...

South is what's north of the north pole :blink:

Exactly,,. which is why it makes you question the basis of the question

The answer isn't 'nothing', but 'there is no logical answer to the question'

Which is why it messes with your head (with or without drink...)
