Sometimes it feels like this could be how we finally make experiments to see what the theory of everything looks like, a bit like the first high energy experiments were from less exotic cosmic rays.

If you point a light detector to any empty area of the sky, you will still get some light.

The existence of this is quite mind blowing, since "there is nothing there emitting that light".

To make sense of how it is possible to see this light, you can think of the universe as the expanding raisin bread model, but it expands faster than light (thus the existence of the cosmological event horizon), so we are still receiving light form the middle, not the borders.

CMB is basically perfectly black-body radiation at 2.725 48 K, but it has small variations with variations of the order of 200 microKelvin: cosmic microwave background anisotropy.

There is a slight variation in temperature of CMB across the sky of the order of 200 microKelvin. It is small to the ~2.7 K average temperature, but it can be measured.

If the initial conditions of the Big Bang and the laws of physics were perfectly symmetric, then we could expect the universe to just be one perfectly uniform boring soup.

But instead some asymetry made all the fun weird things we see today happen eventually, like galaxies and life.

And the cosmic microwave background serves as a way for us to look back in time to the early conditions of the universe, as it was set in stone as soon as the universe became transparent to this light during recombination.

Or if you want to get poetic, it is the closest we can ever get to listening to the original word of God when he setup the initial conditions of the universe.

The ansiotropies of CMB is the ultimate astronomical compass we will ever have, as it is the thing with the least proper motion.

If looking through these don't make you think of the Book of Genesis then nothing will.

Besides the libertarian argument that one has the right to transfer their property to anyone they want, including their family, note that children have been raised and molded by the parent from birth, knowing that they will inherit the family business. As weird as it might seem, simply consider them a continuation of the dead parent; they will now continue administering the business. Then the same arguments as above for respecting private property apply.

There are several ways to make a profit, life would be pretty boring otherwise. Examples include:

But none of these factors are so powerful that a company in a free market can extract exorbitant profits from a customer unwillingly paying with no better choice. Note that intellectual property would not exist in a libertarian system. Of course, people sometimes buy products/services without doing their due diligence or simply not caring enough about ease of quitting, ease of repair, control, etc., and later face difficulties, but that is simply the consequence of their own decisions.

A bass trap is a type of acoustic treatment used to manage low-frequency sounds in a space, such as a recording studio, home theater, or any area where audio quality is important. Bass traps are designed to absorb and reduce bass frequencies that can create problems like muddiness and resonances in the sound.
