Another Confirmation of the General Theory of Relativity

"Einstein proved right in another galaxy" | ScienceDaily

Quote
An international team of astronomers have made the most precise test of gravity outside our own solar system.

By combining data taken with NASA's Hubble Space Telescope and the European Southern Observatory's Very Large Telescope, the researchers show that gravity in this galaxy behaves as predicted by Albert Einstein's general theory of relativity, confirming the theory's validity on galactic scales.

In 1915 Albert Einstein proposed his general theory of relativity (GR) to explain how gravity works. Since then GR has passed a series of high precision tests within the solar system, but there have been no precise tests of GR on large astronomical scales.

It has been known since 1929 that the Universe is expanding, but in 1998 two teams of astronomers showed that the Universe is expanding faster now than it was in the past. This surprising discovery -- which won the Nobel Prize in 2011 -- cannot be explained unless the Universe is mostly made of an exotic component called dark energy. However, this interpretation relies on GR being the correct theory of gravity on cosmological scales. Testing the long distance properties of gravity is important to validate our cosmological model.

A team of astronomers, led by Dr Thomas Collett of the Institute of Cosmology and Gravitation at the University of Portsmouth, used a nearby galaxy as a gravitational lens to make a precise test of gravity on astronomical length scales.

Well done that team!

Very interesting. Some thoughts about dark matter and dark energy were turning to alternatives that DM and DE do not exist and that gravity is not a constant throughout the Universe. Looks like this may be a nail their coffin.
If religions were TV channels atheism is turning the TV off.

Um, Tank, which theory nails 'tother's coffin, please?

Guessing the new theory nails inconstant gravity? Should it prove to have legs that is.

Well it's the new evidence that nails the inconsistent gravity idea.
