Asked in Planetary Science
Is Gold and silver formed on other planets?
Gold and silver - and indeed all the elements are not formed on any planet (though they may be found on planets). the elements Hydrogen and Helium were formed at the begining of the universe during the early stages of the big bang. Later all the other elements up to the mass of Iron were formed from hydrogen and helium in the cores of stars. The elements heavier than Iron are all formed in supernova explosions when big stars explode at the end of their lives. These explosions scatter these new heavy elements out into space where the eventually collapse to form new suns and the planets round these suns. Thus all the Gold and Silver found on earth were formed in dead stars and were part of the dusty disk that formed round our sun in its youth. This disk gave rise to all the planets and therefore there will be some Gold and Silver in all the planets. Elements are not formed on planets (Unless human intervention was involved). Heavy metals like Gold and Silver are formed through fusion inside of a star. As a result, gold and silver should be scattered throughout the universe.
Are black holes fundamental in the universe?
Without an early presence of black holes, it is impossible for galaxies to have formed. No galaxies, no heavy elements near Main Sequence Stars. No such elements near stable stars, no rocky planets that have the time to develop life. No life, no observers. So, black holes are "fundamental" in the sense that a Universe without them would be a Universe without anyone to recognize that there were no black holes!
What ways uranium formed?
Asked in Elements and Compounds
How are elements formed from hydrogen?
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.
