The Laser Interferometer Gravitational Wave
Observatory is spearheading the completely
new field of gravitational wave astronomy and
opening a whole new window on the universe.
LIGO's exquisitely sensitive instruments may
ultimately take us farther back in time than
we've ever been, catching, perhaps, the first
murmurs of the universe in formation. Tags :NSFLIGOLaserInterferometerGravitationalWaveObservatory
The Laser Interferometer Space Antenna or
LISA mission will study the mergers of
supermassive black holes, test Einstein's
Theory of General Relativity, and probe the
early Universe. Detecting gravitational waves
is a new way to observe the Universe. Through
them we will learn more about the mergers of
giant black holes and the death spirals of
stars that black holes capture and swallow.
LISA will look for gravitational waves coming
from our Galaxy and other galaxies. LISA will
also map the structure of space and time
around black holes and determine if
Einstein's theories are correct. Tags :LISAgravityESANASA

ourben has asked the question, "Do like
charges repel, or are they being attracted by
unlike charges elsewhere?" There is a
definite answer to this, but I take two parts
to get there.
The answer is that we know like charges
repel, and Faraday cages can be used to prove
it. Tags :GravitationalElectricalFields
