Leftover Christmas wrapping paper? That the dogs played with.

How many million light years away? More than the big bang?
To: Renfrew
We can observe all sorts of phenomena, and even their effects. But that doesn’t tell us how they really work.
It’s said that ‘no man is an island’. I think that’s true of elemental forces, too.

Two ways this could be wildly wrong, both could apply:
1. The distance is much less than they calculate, meaning the radiated power is also much less than they calculate.
2. The object is not isotropic (radiating equally in all directions), but is instead creating a narrow beam aimed in our direction. Aka the flashlight effect. The initial miscalculation many years ago about AGN (Active Galactic Nuclei) was that they were isotropic, which would have meant the radiated power was ludicrous. Later they discovered black holes were driving the AGN we observed and the high power measured was because we were looking down the throat of the black hole jets.

You are probably more likely to be correct than wrong.
Based on using physics during my career as a mechanical engineer, I am well aware of measurement errors.

The way I understand big bang, it was as close to infinity as one can get, since the whole universe was formed with the big bang. I do not think the big bang was a local event, to measure distance from it.

Practical effect of 97.5% of space exploration on life of a middle class American is close to zero. It is all about curiosity and exercising the brain. Somewhat similar to conquering mount Everest in the early 1950’s. People risked their life to reach the summit. Did that change our lives? Mostly not.
