Einstein's general theory of relativity might be over 90 years old, but
it is only recently that many of its implications can be explored
thanks to advances in computing power. This is because its complex
nonlinear equations -- which describe how space--time is curved by
matter and therefore how matter moves in a gravitational field --
cannot be solved exactly, even for the simplest situations.
Now, Joan Centrella and co-workers at NASA's Goddard Space Flight
Center have made an important breakthrough in numerical relativity by
simulating what happens when two black holes merge. These
extraordinarily powerful events, which occur in the final stages of a
galactic collision, produce copious gravitational waves or "ripples" in
space--time.

But we do not see any, neither do we see flying elephants.

From there it follows that of we could build a device that would pass
Le Sage particles only on one direction, we would have the perfect space drive.
Because of this I think the recent results (if these are correct) from
http://www.esa.int/esaCP/SEM0L6OVGJE_index_0.html
are important and should be further investigated.

If they paid for your education then I agree.

It's a question of discovering quantum gravity. With quantum gravity we
may be able to invent force fields and stable negative energy. Who
wouldn't want that?
