This would be a fusion of three helium nuclei. This would happen towards the end of a star's life, it's not occurring in the sun at present, but obviously has happened in various stars in the past, which is why we have the heavy elements in our solar system
Tritium is formed by the capture of neutrons by deuterium (heavy hydrogen) which is in the heavy water in the moderator and coolant.
Heavy Shreddin' happened in 1990.
Heavy Barrel happened in 1987.
Heavy Unit happened in 1988.
Heavy Rain happened in 2010.
Heavy on the Magick happened in 1986.
Not likely. The Sun and its planets formed from a proto-planetary disk of matter, mostly hydrogen, about 4 billion years ago. However, the disk did include material (heavy elements) that could only have come from a previous stellar system, one that was destroyed by a supernova event.
Such elements are formed within stars. The heavy elements which are currently here on Earth were formed in stars some time ago, and then they were blown into space in supernova explosions.
Heavy elements were formed in stars, and blown out into space in supernova explosions.
Norwegian heavy water sabotage happened in 1940.
Yes, colloid is a type of solution where particles are suspended in a medium, such as water. Creek water after heavy rain may contain suspended particles like dirt, sand, and organic matter, making it a colloid solution.
