Inside the Ice Man Dark Matter Mystery and Fukushima Cleanup

The video covers three topics: the genetic analysis of the 5300-year-old Iceman Ötzi, revealing his health predispositions and ancestry; a perplexing observation of dark matter behavior in galaxy clusters, challenging current astrophysical theories; and the ongoing issues surrounding radioactive waste management following the Fukushima nuclear disaster, highlighting the long-term challenges posed by isotopes like cesium 137.

What was one of the surprising health conditions discovered in Iceman Etsy?

• He was lactose intolerant.

• He had blue eyes.

• He had type A blood.

• He was immune to Lyme disease.

What is a unique characteristic of dark matter that makes it difficult to observe?

• It is visible through telescopes.

• It reflects light.

• It emits bright light.

• It does not emit or reflect light.

What unexpected observation was made about the galactic cluster ABL 520?

• The dark matter disappeared completely.

• The galaxies moved away from the dark matter.

• The galaxies and dark matter remained together.

• The galaxies merged with the dark matter.

What is the half-life of iodine 131, one of the isotopes from the Fukushima disaster?

• 30 years

• 100 days

• 8 days

• 1 year

Why is cesium 137 particularly concerning in terms of health effects?

• It decays within a few days.

• It is harmless to humans.

• It can be absorbed by various body cells.

• It has a short half-life.
