Ray Kurzweil discusses having a universe filled with Computronium.
He discusses this happening within 200 years if wormholes or some other means allow faster than light travel.
What would the computation limits of computronium be?

In June of 2018 we posted that a team of physicists explored the possibility that the black holes we ‘observe’ in nature are no such thing, but rather some type of exotic compact objects (ECOs) that do not have an event horizon. The scientific collaborations LIGO and Virgo have detected gravitational waves from the fusions of two black holes, inaugurating a new era in the study of the cosmos. But what if those ripples in space-time were produced wormholes that can be traversed to appear in another universe.
“Wormholes do not have an event horizon, but act as a space-time shortcut that can be traversed, a kind of very long throat that takes us to another universe,” says Pablo Bueno from KU Leuven University (Belgium). “The confirmation of echoes in the LIGO or Virgo signals would be a practically irrefutable proof that astrophysical black holes don’t exist. Time will tell if these echoes exist or not. If the result were positive, it would be one of the greatest discoveries in the history of physics.”

Scientists say that something mysterious punched gigantic, cosmic “bullet holes” in parts of the Milky Way.
There’s a string of holes in a long stream of stars called GD-1 that suggests that some yet-undiscovered thing blasted its way through, according to research presented to the American Physical Society last month and first reported by Live Science. Harvard-Smithsonian astrophysicist Ana Bonaca, the scientist who discovered the cosmic crime scene, suspects that the gigantic “bullet holes” may have been carved out by invisible dark matter.
Whodunnit
Unfortunately, the culprit of this celestial shooting seems to have gotten away with it — Bonaca told Live Science that there’s no evidence at the crime scene beyond the size of the gaps in the stellar stream.

Dark matter is an unknown type of matter present in the universe that could be of particle origin. One of the most complete theoretical frameworks that includes a dark matter candidate is supersymmetry. Many supersymmetric models predict the existence of a new stable, invisible particle called the lightest supersymmetric particle (LSP), which has the right properties to be a dark matter particle.
The ATLAS Collaboration at CERN has recently reported two new results on searches for an LSP that exploited the experiment’s full Run 2 data sample taken at 13 TeV proton-proton collision energy. The analyses looked for the pair production of two heavy supersymmetric particles, each of which decays to observable Standard Model particles and an LSP in the detector.

The results are fascinating and spur the imagination, but don’t start investing in flux capacitors yet. This experiment also shows us that sending even a simulated particle back in time requires serious outside manipulation. To create such an external force to manipulate even one physical particle’s quantum waves is well beyond our abilities.
“We demonstrate that time-reversing even ONE quantum particle is an unsurmountable task for nature alone,” study author Vinokur wrote to the New York Times in an email [emphasis original]. “The system comprising two particles is even more irreversible, let alone the eggs — comprising billions of particles — we break to prepare an omelet.”
A press release from the Department of Energy notes that for the “timeline required for [an external force] to spontaneously appear and properly manipulate the quantum waves” to appear in nature and unscramble an egg “would extend longer than that of the universe itself.” In other words, this technology remains bound to quantum computation. Subatomic spas that literally turn back the clock aren’t happening.

A new theory proposes that faster-than-light particles known as tachyons could answer a lot of questions about the universe, writes Robyn Arianrhod.
The image mosaic was created using 16 years’ worth of data from the Hubble Space Telescope, and it shows roughly 265,000 galaxies stretching back 13.3 billion years, to just 500 million years after the Big Bang.
Background: This isn’t the first Hubble deep-field image. The first one was released back in 1995, with further deep-field images following in 2003, 2004, and 2012. However, this is by far the most comprehensive. It was created by weaving together several of the previous Hubble photos. The image, dubbed the Hubble Legacy Field, represents 7,500 separate exposures. It contains about 30 times as many galaxies as the previous shots. The image above is just a section of the whole: you can see the full thing here.
A time machine: Because many of the galaxies Hubble captures are so far away, it has taken billions of years for their light to reach us. That makes the telescope a sort of time machine, letting us see galaxies as they were billions of years ago.
