Until we have definitive direct evidence of dark matter in the form of WIMPS, axions, etc. Magazine issue Scientists Say It’s Too Early to Tell Want it all? We know it is there, it is not a hypothetical things which is not observed, as was the aether. The dark matter particles could warm a planet for trillions of years. All this mysterious “dark matter” and “dark energy” is much alike the need for “ether” at the end of the 19th century. “This is the ultimate form of sustainable energy,” Hooper told That could come in handy far into the future, when stars have exhausted their nuclear fuel and died. David Schramm & Gary Steigman (if I remember the 2nd name right) did a calculation to examine various scales, starting with binary galaxies & small groups through to the scale of observable universe, towards end of 1970s. Sign in to manage your newsletter preferences The Italian and Chinese physicists on the DAMA Project have held out since 2000 for their claim that they are detecting dark matter. (i.e. “You’d lose the water and end up with a By weak lensing I presume this means for small Newtonian gravity. In a new paper uploaded to Hovering, Flying, and Hopping Across the Solar SytemCan You Get COVID-19 Twice?
I have pondered whether some of the solid state approaches to quantum computers might work here.
This is still a rather vexed issue. we should be a bit cautious about our interpretation of the indirect evidence.DAMA has reported some signal, but the statistics are still too rough to draw conclusions. (Credit: NASA) Dark stars may not just be for Grateful Dead fans anymore. Explore Wikis; Community Central; Start a Wiki; Search Sign In Don't have an account? Theoretically, dark matter could be invisible normal matter, but this is likely to be only a small amount of the Universe’s missing mass.These objects, collectively known as MACHOs (Massive Astrophysical Compact Halo Objects), emit very little light, but they can be detected if they pass in front of or near a background object (via the way that their gravity bends the light from the more distant object).However, studies to date have concluded that MACHOs can only account for a tiny fraction of the missing mass in the Universe. A small DM interaction with the nitrogen in a diamond lattice (one approach to quantum computing) might flip a quantum bit. I think this issue needs very urgently to be settled.

A larger DAMA/LIBRA experiment reaffirms the phenomenon, which appears as flashes in the team’s sodium iodide detector. If you mean specifically the convergence of wordlines you see looking back, no it doesn’t, if you take inflation seriously. “Dark whatever” will eventually drift to the sidelines of the history of science. This might be a surprise, but we don’t know what most of the universe is made of. “They’re talking about a tiny fraction of possible cases.”That’s because these dark-matter-rich areas are so far away – 26,000 light years – that even if the presence of planets could be detected, current and planned telescopes would not be able to image them, looking for signs of water.“We’re most interested in stars within about [65 or 100 light years] of the Earth because we think we can build a big telescope sometime within the next 20 years to try to image planets around them,” Kasting told If dark matter does interact as Hooper and Steffen have calculated, though, it could produce too much heat for life to survive on some planets, frying those that are also getting heat from their host stars.

Register Start a Wiki. Although most people jump on the bandwagon of needing dark matter to connect mass distribution to rotation curves, there are a few independent lines of evidence to suspect that the sums haven’t been done right, but subscribed to by most people for so long that it’s now too much against the stream to say that they were wrong in the first place.
