2 locks and dams have shutdown operations and more is expected. Once Smithland lock and dam shuts down then the Ohio is effectively closed from Paducah on up. The dam at Louisville is shutting down today.
A new study suggests that Earth may lie within a massive, matter-deficient region of space—called the KBC supervoid—spanning 2 billion light-years. This vast underdensity could help resolve the Hubble Tension, the puzzling mismatch in the universe’s measured expansion rate.
Distant observations (like the cosmic microwave background) suggest a slower expansion rate of 67 km/s/Mpc, while nearby measurements (from supernovae and Cepheids) give a faster rate of 73 km/s/Mpc. Researchers believe the supervoid’s gravitational effects may be distorting our local view, making nearby galaxies appear to move faster than they truly are.
Even more intriguing, this immense void poses a challenge to the standard model of cosmology, which assumes a uniform matter distribution and relies on dark matter. Instead, the findings align better with Modified Newtonian Dynamics (MOND)—a bold alternative to dark matter that tweaks the laws of gravity.
If confirmed, this could mean we’re witnessing the first major shake-up in cosmology since Einstein—hinting that our place in the universe might be affecting how we see the cosmos expand.
📸 Upcoming missions like Euclid and Roman will put this radical idea to the test.

Now don’t get your Best Buy briefs in a bunch there little fella. Picked up this one from the big blue box you called your second home a couple years back when you fellas told me to get a mesh extender.
Reset it and to @VegasFrank ’s dismay, Zoom worked far better this evening.
