PSI Blog 20201214 Cosmogonical Laugher—Imagined Aliens Might be able to Stop Imagined Expansion of the Universe
Cheer up! Here is some cosmic
comedy from MIT’s cellar. I can’t even imagine how anyone could get tax money to work on this latest absurdity:
“An Advanced Civilization
Could Resist the Accelerating Expansion of the Universe
And Earth-bound
astronomers should be able to tell if someone is out there doing it, a
physicist says”
The author comes up with a
list of worries, including Covid, depression, and climate that might be of
concern and writes:
“But one threat that is near
the bottom of the list is the accelerating expansion of the universe. Indeed,
it hasn’t been considered a clear threat at all until now.
Today that changes, at least
a little, thanks to the work of Dan Hooper, a particle physicist at the Fermi
National Accelerator Laboratory in Batavia, Illinois… a new twist to the tale.
His idea is [from old-time regressive Freeman Dyson] that an advanced
civilization could build a sphere [around the Sun] that emits waste radiation
in a specific direction. This radiation would accelerate the sphere — and the
star it contains — in the opposite direction.
Over time, an advanced
civilization could use this technique to gather stars as a source of energy and
thereby keep them inside the cosmic horizon as the universe expands.”
So much
for your cosmogonical sci-fi lesson for the day…

The Blogger / Google login status, and the ability to post comments, is sensitive to both cookie and script filters. Your readers may need to enable (stop filtering) "third party cookies", in their browser and on their computer. The effects of the newly unavoidable CAPTCHA, and the Google "One account" login, requires third party cookies, even more than before.

Third party cookies filtering, in a browser setting, is the most common solution, overall - but your readers may have to search for other filter(s) that affect their use of Blogger / Google.
Any filters are subject to update, by the creator. If the problem started a few days ago, your readers may have to look on their computers, and find out what product or accessory was updated, a few days ago.
