I was not familiar with Harald Lesch, who I see is prominent in the field of Astrophysics and a science populariser in Germany. Mostly published in German I think. Can you give me a link to his negative comments on the possibility of LANR/CF, because I can't find any references myself?
@Alain: Lesch is a popular wide screen talker - not a serious scientist, sometimes paid by big pharma or food companies. He fight's (well paid) for vacination at any price and against homeopathy.
The universe would expand forever and never end, but to humanity in the far future, look about the same as it does today.
axil : That's exactly what Einstein (his ART theory) didn't say.
Regarding dark matter: I just ask everybody to wait some more years. Currently we live in a speculation phase, where every day at least one new theory is presented. As about physics (ether, atomic nucleus) too, where we know nothing compared to what one could know...
