The opposite process, nuclear fusion, where nuclei are joined together, also releases energy. |
Normally, stars balance the gravitational force with the pressure from the nuclear fusion reactions inside. |
These dark nebulas are places where new stars are beginning their gravitational collapse and have yet to begin nuclear fusion. |
I used to be a designer draughtsman working on the nuclear fusion project at the Culham laboratories in Oxfordshire. |
Unlike stars like the Sun, brown dwarfs don't have enough mass to generate energy through nuclear fusion. |
Various propulsion schemes have been proposed, from nuclear fusion to antimatter to laser sails. |
