Do We Need to Revise General Relativity?

An interesting article.

According to the modified gravity theory, an offshoot of MOND, a black hole's shadow should be ten times larger compared to what general relativity predicts. The Event Horizon Telescope aims to image a black hole and its shadow for the first time in 2017.

Great that they can soon test it.

You deniers are going to destroy the gravity credit market. The science is settled.

[ganeemead]

There is no such thing as “dark matter”. Galaxies are held together by electromagnetic forces, not gravity.

[thoughtomator]

Of course we do. Trying to keep general relativity together has led to extreme absurdities like assuming the universe is over 19 parts in 20 composed of stuff we have no way to detect and doesn’t interact with anything (other than to magically and conveniently correct the errors in general relativity).

Plasma cosmology - a universe dominated by electromagnetism, rather than gravity - is providing answers that make sense where institutional science repeatedly fails.

Oh man. I was going to post “The science is settled.” but you beat me to it!

Well, you know, if the Navy gets a hold of it, they’ll rename it “Admiral Relativity”, and then we’ll really be in trouble.

Thanks rdl6989.

I thought General Relativity lost his command in some kind of scandal.

[Paine in the Neck]

...they surmised that either there must be some huge unseen mass driving the rotation, or that the laws of gravity given by Einstein's General Relativity need to be changed.

Maybe they should be asking themselves if something other than gravity is at work before conjuring up all these ad hoc just-so stories.

Didn’t Obama fire him because he wouldn’t order his troops to collect guns from Ameri....uh, um, oh, never mind!

[brivette]

let’s not be general..

[ctdonath2]

Do enlighten us.

[Tenacious 1]

Why do we assume that gravity and the speed of light are the same and constant throughout the universe? It is assumed that the mass of something can predicts its gravitational force (and vica-versa). What if gravity is proportional based on the location, temperature and/or speed of the mass? If dark matter has no mass, can it be matter at all?

I’ve always thought Newton was a fraud.

It depends on your point of view.

[Bloody Sam Roberts]

It’s all those Midiclorians that have gone over to the Dark Side.

[Bloody Sam Roberts]

Agreed. It’s all nonsense.

There is a series of books, “Hidden in Plain Sight” (used to be 99 cents each on Kindle), that suggests something along these lines too. I enjoyed the books, not too heavy, and thought provoking if you’ve spent time pondering physical “reality.”
