Dark energy: Einstein was wrong, and right

Scientists studying data from the European Southern Observatory's Very Large Telescope in Chile were able to reproduce their observations of galaxies' movements going back 7 billion light-years. This is pretty impressive by itself, but they say it also reveals the truth of Einstein's "cosmological constant"--the activity of "dark energy"--which he introduced, then later disavowed.

a light-year is a measurement of distance, not time.

A light-year is a measurement of distance, but, the light arriving here now from these galaxies represent the galaxies as they were 7 billion years ago. So the statement in the article is correct.

It is well known that Einstein couldn't even do simple math. So of course he would get his formulas mixed up and got the wrong results. That is how he could be both right and wrong at the same time. That is how quantum math is supposed to work.

Please, don't shout your ignorance from the rooftops. Relativity is a highly mathematical theory - I can assure you Einstein had a pretty good knowledge of maths. And realtivity and quantum theory are utterly different. Unless physics and maths have changed since I did my degree.

All of this cited evidence stems from the assumption that red shift is caused by the light emitter speeding away from the observer and causing a Doppler wavelength shift . Some physicists believe this to be incorrect. Dr. Milo Wolff is one such physicist and those interested in an alternate view might be interested to read his article on the subject found here: http://www.quantummatter.com/_Media/Astron-CosmolWebSite.pdf
