Have they decided on the fate of Hubble yet?

...Advances in computer technology now allow us to simulate the entire universe...

In a coarsely gridded sort of way.

Invisible, yet undoubtedly there — scientists can measure its effects — its exact characteristics remain elusive.

Unlike normal matter particles, physicists believe, they do not collide and scatter like billiard balls but rather simply pass through each other.

Collisonless? Invisible? Apparently do not interact with other matter, including dark matter? Yet, dark matter shapes most of the universe?

I'll bet that changes in these theories will be forthcoming in the near or slightly more distant future. Tough I probably won't be around to read about it.

The universe is always newsworthy.

Another story about the same dumb ol' universe. Doesn't anyone ever broaden out a little?

[LLoyd George]

"it is very challenging to verify the simulation results observationally"

Really? (Not surprisingly!)

"Dark matter [is] invisible, yet undoubtedly there"

You can count me as a doubter. Dark matter is a contrivance to fill the gaps in otherwise sensible theories.

I find it much easier to believe the fine structure constant and light velocity have changed over the history of the universe.

To me this is a more rational explanation of measurements that seem to indicate an accelerating universe and gravity with no apparent matter.
