Not necessarily all, but there are a lot of them. NASA thinks that zero point energy and vacuum energy are worth investigation, at least. These ideas are part of their long-term research concepts in http://www.space.com/businesstechnology/technology/advanced_propulsion_020522-1.html [Broken]Originally posted by wolram

For no particularly good reason, some of us took Latin in high school. Gravis means heavy and the opposite of gravis is levis.Originally posted by elas
Sakharov of the Russian Academy was the first to propose that ZPE in a vacuum and gravity are one and the same entity in 1976. His work was not published in the west until 1983 when a USA physicist was about to publish a similar paper. Eventually they agreed to a joint publication in Physics Review under both names.
Look at Newton's concept of corpuscular gravity and you will see that it has a zero point at its centre so Newton was actually way ahead of the field although he failed to realise the significance of the zero point.
Now add a line to Newton's graph and you have the so-called anti-gravity. It is then only necessary to realise that the 'anti-gravity' force is created by the adjacent gravitons, to realse that there is no such reality as 'anti-gravity' but, only Newton's corpuscular gravitons (i.e. vacuum fields) acting in opposition to each other. That is to say that gravity is its own anti-force.
