It sure can - and some stars do, to a minor degree. However, it can no longer gain energy from this fusion - it costs energy to create heavier elements.

To fuse Iron, you would need a huge amount of heat and pressure, higher than what can be provided by even the massive stars is existence. The upper limit of a stars mass puts this limit on what materials it can fuse. Elements heavier than Iron are created during a supernova explosion, the death of a massive star.

What were the heavier elements in the universe for by?

Heavier elements in the universe were primarily formed through processes such as stellar nucleosynthesis and supernova explosions. Inside stars, lighter elements like hydrogen and helium fuse under extreme temperatures and pressures to create heavier elements up to iron. Elements beyond iron are generally formed during supernova events, where the extreme conditions allow for rapid neutron capture processes (r-process). These heavier elements are then released into space, contributing to the formation of new stars, planets, and ultimately, life.


Nuclear fusion only releases energy when elements that are lighter than what element are involved?

Nuclear fusion only releases energy when elements lighter than iron are involved. This is because elements lighter than iron release energy due to the process of fusion, while elements heavier than iron require energy to be input for fusion to occur.


What were the heavy elements in the universe formed by?

Heavy elements in the universe were primarily formed through processes such as stellar nucleosynthesis and supernova explosions. In stars, lighter elements fuse under extreme temperatures and pressures to create heavier ones, with elements beyond iron typically formed during supernova events when massive stars explode. Additionally, neutron capture processes, like the r-process and s-process, contribute to the formation of various heavy elements. These processes occur over cosmic timescales, contributing to the elemental diversity observed in the universe today.


Does It takes less and less time to fuse heavier and heavier elements inside a high-mass star?

Yes, it takes less time to fuse heavier elements inside a high-mass star because the higher the mass of the star, the higher the core temperature and pressure, which accelerates nuclear fusion reactions. As the star runs out of lighter elements to fuse, it progresses to fusing heavier elements at a faster rate until it reaches iron, at which point fusion stops and the star undergoes a supernova explosion.


What role did supernova play in creating the natural elements?

It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.
