When Albert Einstein defined the gravitation as a deformation on the space shape he revoluted a new world of ideas, one of those are the gravitational waves? Sounds like ilogical but this theory has strong bases, if the Einstein's theory about gravitation its true that means that a certain mass can deform the space, more the mass more the deformation, imagine a water filled bed (thats the space seen from just three dimesions) if you put a mass over the bed it sunks and deform the bed, now place a smaller mass near the firstone, it shall fall in the hole until reaches the bigger mass, that was gravitation for Einstein. now there should be a way to describe that deformation in the space in shape of waves, these new theory includes the time, says that near a huge mass the time goes slower, so near a blackhole of infinite mass the time would stop... intersting? it doesnt ends... The NASA and other agencies are working on the LISAproject, this is an ambicious project that uses laser thechnologies to DETECT and MEASURE the deformation of the space and even time caused by the gravitational waves, this shall demostrate almost 100 years later that Einstein was right or wrong, find more about the LISA project in http://lisa.nasa.gov/

Well when you speak of space or time it's all a matter of interpretation. Space and time are abstract notions. If matter does bend space then that space it's more than sure not empty space since empty space is an abstract notion: The representation of nothingness (which by definition can not be bend, you can't bend "nothing"). So I prefer to think that mass "seems" to bend space as matter seem to act near masses as space would have been bend. (But still, space as 3D coordinates it's a mathematical system ergo an abstract system)
