Was never much of a chemistry interested so just realizing this is fascinating. Hydrogen is here thanks to oxygen otherwise would escape Earth gravity.

we actually lose roughly 3 kilograms per second of hydrogen and 50 grams per second of helium!

Seriously????!!!!! Now I regret or not that chemistry when I was in school went into one ear and as soon as I finished with the grades it exited through the other ear. Maybe if I knew more I wouldn’t be as fascinated to discover this within the context of today’s understanding of the world and art. You mean we lose this on a planetary level, and was it always the same? Or depends on climatic conditions. How was during ice ages?

The earth loses that amount, which is a miniscule amount. what i tend to find is the more i know the more i realise i dont know that much. "To describe the theory of thermal atmospheric escape, one starts with the concept that at a high altitude, which is around 500-600 km for Earth, the frequency of collisions between gas particles becomes negligible. Above this “exobase” is the “exosphere”, where a planet’s atmosphere merges into the vacuum of space. At the exobase, ascending particles are unobstructed, so particles fly away into space if they are moving upwards faster than the escape velocity. Below the exobase, collisions confine the particles. " Catling & Zahnle et al

Fascinating indeed and about the knowledge yes the large the circle of knowing the larger is the outside. This is the right way, also explanation why those with small circles of knowledge tend to be so confident vs those with large circles. Just one more dumbo question from my side. The amount of hydrogen and helium that we lose per second, does it get replenished or is just gone and unnoticeable because there is so much of both

Thats a yes and a no (and i dont know for certain). Basically yes it does replenish the gasses because of things like volcano eruptions, exchange between our oceans and atmosphere, plant decomposition, photosynthesis. The no is because we're not gaining much more matter other than from perhaps asteroid impacts, its whats already on/a part of Earth changing from one state to another.
