The researchers also accounted for an odd feature
of general relativity in which clocks at different heights keep different times.
We will have to have in our hands the full quantum theory of gravity [a
combination of general relativity and quantum mechanics, yet to be understood] to find out the answer.
There is simply no better introduction to the strange
wonders of general relativity and quantum mechanics, the fields of knowledge essential for any real understanding of space and time.
Over the past decade or so our theoretical
understanding of general relativity has improved a great deal, allowing us to calculate the precise pattern of gravitational waves it predicts for such a merger.
Einstein's famous theory
of general relativity predicts the existence of gravitational waves, but it's taken humanity over a century to develop the technological know - how to build a detector sensitive enough to perceive them.
Also, by showing that the gravitational field isn't smooth but quantised, like space itself, it would point toward a theory of quantum gravity, the long - sought reconciliation
of general relativity with quantum mechanics.
This detection has, in a single stroke and for the first time, validated Einstein's theory
of general relativity for very strong fields, established the nature of gravitational waves, demonstrated the existence of black holes with masses 30 times that of our sun, and opened a new window on the universe.
«We still don't understand exactly how the corona is produced or why it changes its shape, but we see it lighting up material around the black hole, enabling us to study the regions so close in that effects described by Einstein's theory
of general relativity become prominent,» said NuSTAR Principal Investigator Fiona Harrison of the California Institute of Technology (Caltech) in Pasadena.
Now, physicist Clifford Will has calculated another effect
of general relativity on Mercury's orbit, he reports in a paper accepted in Physical Review Letters.
This «anti-gravity» effect is represented in Einstein's equations
of general relativity by a term called the cosmological constant.
A new way to test one of the basic principles underlying Einstein's theory
of General Relativity using brief blasts of rare radio signals from space called Fast Radio Bursts is ten times, to one - hundred times better than previous testing methods that used gamma - ray bursts, according to a paper just published in the journal Physical Review Letters.
He sought an
extension of general relativity that would incorporate electromagnetism, thereby wedding the large - scale world, where gravity dominates, with the small - scale world of quantum physics.
«And our results confirmed the
validity of General Relativity at the 0.05 % level, which is by far the best precision yet achieved for the strong - field regime.»
Skeptical at first, scientists slowly began to accept the idea in the ensuing decades, as more evidence supporting Einstein's theory
of general relativity came to light.
