Web“Cosmic Vision 2015-2025” is the current planning cycle for ESA’s space science missions. It was created in 2005, and is predated by the Horizon 2000 plan prepared in 1984, and Horizon 2000 Plus, which was drawn up in 1994–95. To put these plans in context, Rosetta and its lander Philae began life in Horizon 2000. Web16 apr. 2010 · The Inflation Theory, developed by Alan Guth, Andrei Linde, Paul Steinhardt, and Andy Albrecht, offers solutions to these problems and several other open questions in cosmology.
