2Physics Quote:
"Stars with a mass of more than about 8 times the solar mass usually end in a supernova explosion. Before and during this explosion new elements, stable and radioactive, are formed by nuclear reactions and a large fraction of their mass is ejected with high velocities into the surrounding space. Most of the new elements are in the mass range until Fe, because there the nuclear binding energies are the largest. If such an explosion happens close to the sun it can be expected that part of the debris might enter the solar system and therefore should leave a signature on the planets and their moons." -- Thomas Faestermann, Gunther Korschinek (Read Full Article: "Recent Supernova Debris on the Moon" )

'Inertial Confinement'

The "inertial confinement" technique uses lasers or ion beams rather than
magnets to confine the plasma. This will be investigated by the National
Ignition Facility (NIF) in the US and the Laser M├ęgajoule (LMJ) in France.
However, both these billion-dollar lasers will primarily be used for nuclear
-weapons research, with only 15% of their time being available for other
areas of physics. In this conventional approach to inertial confinement, the
lasers that compress the fuel capsule also heat it.

Hi,

Can you post some links and details about such topics.

IMO, it really doesn't serve the purpose when your posts are this short. Just my 2 cents.

Thanks for the links. The link to ucb IFE details the whole concept and the programme with the limitations behind it.

I really appreciate your effort !
