Are Black Holes Unfalsifiable and Therefore Not Science?

In summary, the article asserts that the existence of black holes cannot be falsified, and therefore they do not qualify as science. Some people have argued this before, though it is a controversial topic.

An observer inside an event horizon would suffer from reverse redshift. He/she would 'see' the universe age at infinite speed according to GR. Draw the light cone.

observer inside the horizon reaches signularity in finite time. You mean, he will see everything before he hits singularity? this is not true and I am ready to draw a lightcone.

My error, you are correct. Time will gradually speed up as observer approaches the singularity.

in GR all coordinate systems are equally vaid. So in some coordinate systems BH forms in finite time. In the others we lose communication with the inner parts of BH.

Would you then argue just as animatedly against claims the existence of black holes?
