Very fascinating…I always thought of earth as the ‘blue’ planet, the ‘water planet’…quite instructive…thank you!

As shown in Hollywood movies and few articles in google does inside the earth is hollow earth?

Is there life different there how life is there inside earth what are the natural situation and conditions there?

Ladies ad Gentlemen,

In the sulphur content of Io sent to swirl around Jupiter we see depositions of the red material upon nearby Europa.

If we see emergence of life from Europa, do we see any mechanism for that life in water to transit to the better electromagnetic protection of Ganymede?

Then life can be sustained from cosmic rays, mostly protons, and from the GRB slow and fast supernova and collapsed core object impacts.

Thanks to Prof. Dimitar for the excellent lecture.

Great explanation.

The video’s argument suggests that we might need multiple overlapping definitions of life depending on the context — one for searching microbes on Mars, another for theorizing about post-biological civilizations, and another still for artificial life we might create ourselves.

So yes — like the video, I think the NASA definition is a useful starting framework, but not the final word. It’s built for our current level of technology and understanding, but the universe likely contains forms of life (or life-like systems) that challenge every box we try to put them in.

Life as a planetary phenomenon means that life and a planet are closely connected and influence each other. On Earth, life not only depends on the environment but also changes it, for example by producing oxygen and affecting the climate. Therefore, life is an active part of a planet, not just something that lives on it.

Great explanation

Life at the surface means organisms living on or near a planet’s surface, where they interact with sunlight, air, and water. On Earth, most life exists at the surface because it gets energy from the Sun and essential resources from the environment
