Dark matter nightmare: What if we are just using the wrong equations?
---
Einstein’s theory of general relativity is an extremely well-confirmed theory.
Countless experiments have shown that its predictions for our solar system
agree with observation to utmost accuracy.
But when we point our telescopes at larger distances, something
is amiss. Galaxies rotate faster than expected.
Galaxies in clusters move faster than they should.
The expansion of the universe is speeding up.

General relativity does not tell us what is going on.
#
Is dark matter a particle, and if so what type, and how can we measure it?
If it is not a particle, then what do we change about general relativity
to fix the discrepancy with measurements?
Is dark energy maybe a new type of field?
Is it, too, made of some particle?
Does dark matter have something to do with dark energy or are the two unrelated?

To answer these questions, hundreds of hypotheses have been proposed,
conferences have been held, careers have been made – but here we are,
in 2019, and we still don’t know.

Bad enough, you may say, but the thing that really keeps me up at night is this:
Maybe all these thousands of physicists are simply using the wrong equations.
I don’t mean that general relativity needs to be modified.
I mean that we incorrectly use the equations of general relativity to begin with.

Astrophysicist claims "dark fluid" fills the missing 95% of the Universe
An Oxford scientist's controversial theory rethinks dark matter and dark energy.

An astrophysicist and cosmologist Dr. Farnes published
a paper while at Oxford University with a novel
explanation for dark energy and dark matter.
His theory claims to explain the missing 95%
of the observable universe by the existence of "dark fluid".
This fluid has negative mass, repelling other materials.
