In the early days of the solar system, Earth likely collided with another massive body, causing the Moon to orbit our planet. According to current theories, it was this event that would make the Earth and the Moon relatively dry compared to the other planets in our system. During the collision, various “volatile” substances were thrown into space, but at the same time the water was supposed to hit the Earth. Recent research appears to contradict this.

Scientists from Lawrence Livermore National Laboratory decided, based on the amount of isotopes of rubidium and strontium (an indicator of the amount of water on the Moon) in the Earth-Moon system, that the object that contributed to the formation of our satellite must have been very “dry”.

Greg Brenica, co-author of the latest research, explains, and adds:

At the same time, we invite you to listen to the latest episode of the podcast from a technical point of view. This time we talked about the introduction of DVB-T2 / HEVC to Poland, which, due to the change, has to replace televisions and the so-called “Ukrainian trap”. Do owners of compatible TVs have to do anything when the new standard comes and how to check if the current device meets all the requirements?
