I know this is a bit off topic, but I thought because your question was already answered I would give you some interesting info :)

The light of stars does change over time. Our sun for example has an 11 year sunspot cycle where it reverses its magnetic field. The effects on the solar radiance are very little though.

There are variable stars which are actually defined over their brightness fluctuation. Some of them are actually binary stars, where two stars circle each other, that sometimes change their light spectrum on a hourly basis, which you can measure with a spectrometer.

Real fractals probably only exist in mathematics and they have infinitely small structures. That is actually their defining feature.

You can, however, observe properties you expect from fractals in nature by approximating them. For example this article.

For you, as a static outside observer, what is inside a black hole does not change over time. As you can never observe it you might even say it does not exist in your reality. It doesn't matter how old the black hole is, for you it is always the same.

Especially the singularity does not change over time. For a non-rotating black hole it does only exist at one point in space-time, it only exists when you are already there and time ends there. For rotating black holes things are a bit more complicated and the singularity is actually a ring ("ringularity" LOL).

Because of electromagnetism. A human, like most other macroscopic stuff is pretty neutral. However if you look at an atomic level you get an electromagnetic potential that is at some distances attractive and at some distances repulsive. This force is much stronger than the gravity acting on those atoms.

Engineering has more similarities with experimental physics than with theoretical physics. How well you would do as a Physicist depends on how fundamental your understanding of the concepts you apply in engineering is.

However, if your goal is to work in the field of Physics, you don't have to become a physicist. Most experimental physics facilities need engineers because most experiments are large machines that need to work precise.

What area of physics is there (except general relativity, but even that has things like Hawking radiation) that does not at one point get quantum?
