The reason we call dark matter dark isn’t because it’s some shadowy material. It’s because dark matter doesn’t interact with light. The difference is subtle, but important. Regular matter can be dark because it absorbs light. It’s why, for example, we can see the shadow of molecular clouds against the scattered stars of the Milky Way. This is possible because light and matter have a way to connect. Light is an electromagnetic wave, and atoms contain electrically charged electrons and protons, so matter can emit, absorb and scatter light. Dark matter isn’t electrically charged. It has no way to connect with light, and so when light and dark matter meet up they simply pass through each other. All of our observations suggest that dark matter and light only have gravity in common. When dark matter is clustered around a galaxy, for example, its gravitational tug can deflect light. Because of this we can map the distribution of dark matter in the Universe by observing how light is gravitationally lensed around it. We also know that dark and regular matter interact gravitationally. The tug of dark matter causes galaxies to gather together into superclusters. But an unanswered question is whether dark and regular matter only interact gravitationally. If an atom and dark matter particle intersected, would they really just pass through each other? Since we haven’t directly observed dark matter particles we can only speculate, but most dark matter models argue that gravity is the only common link with light and regular matter. Dark and regular matter clump around each other, but they don’t collide and merge like interstellar clouds. But a new study suggests the two do interact, which could reveal subtle aspects of the mysterious stuff. The study looks at six ultrafaint dwarf galaxies, or UFDs. They are satellite galaxies near the Milky Way that seem to have far fewer stars than their mass would suggest. This is because they are mostly made of dark matter. If regular and dark matter only interact gravitationally, then the distribution of stars in these small galaxies should follow a certain pattern. If dark and regular matter interact directly, then this distribution will be skewed. To test this the team ran computer simulations of both scenarios. They found that in the non-interacting model the distribution of stars should become more dense in the center of the UFDs and more diffuse at the edges. In the interacting model the stellar distribution should be more uniform. When they compared these models with observations of the six galaxies, they found the interacting model was a slightly better fit. So it seems dark and regular matter interact in ways beyond their gravitational tugs. There isn’t enough data to pin down the exact nature of the interaction, but the fact there is any interaction at all is a surprise. It means that our traditional models of dark matter are at least partly wrong. It may also point the way toward new methods of detecting dark matter directly. In time we may finally solve the mystery of this dark, but not entirely invisible, material. Reference: Almeida, Jorge Sánchez, Ignacio Trujillo, and Angel R.

JD Vance Destroys Kamala’s ‘Middle Class’ Narrative In About Two Minutes [WATCH]

Words will always retain their power. For those who will listen, Words are the annunciation of TRUTH. And the truth is there is something terribly wrong with this Country, isn’t there? Currently we have injustice, intolerance and oppression, where once we had the freedom to think, object and speak out as you saw fit. NOW you have systems of mass surveillance, censorship on social and print media, 24 hr televised propaganda coercing your conformity and Soliciting your Submission. How in the HELL did this happen? Who is to Blame?? There are those who are more responsible than others and they will be held to Account. Honesty, Fairness, Justice, and Freedom these are more than words They are Perspectives If YOU Know as I Know If YOU Feel as I feel If YOU LOVE Our Australia as I Love it Then we must set a Date to Restore Her Freedom, Her Honesty, and Her Courage and Her Right Standing. May I say GOD BLESS Australia. WITH THANKS TO TIM'S TRUTH (AUSTRALIA) https://rumble.com/user/TimsTruth

UTL COMMENT:- Russel Brand self declared Socialist flying with Predator and child rapist P Diddy.

MSNBC host Stephanie Ruhle called out Vice President Kamala Harris for not answering her question on how she plans to raise taxes with what would likely be a divided government. In a preview clip of her interview with the Democratic nominee that aired Wednesday, Ruhle pressed where Harris would "get the money" to fund her pricey economic proposals if Republicans on Capitol Hill block her efforts to raise the corporate tax rate. "Do you still go forward with those plans and borrow?" Ruhle asked...

This year will be the first year since 1958 that the Bureau of Ocean Energy Management held no offshore oil and gas lease sales. Energy expert Alex Epstein, author of “Fossil Future,” argued at a recent House Budget Committee hearing the United States' record-high oil production is in spite of the Biden-Harris administration’s policies, not because of them. The data suggests he could be right, which means the impacts of the administration’s energy policies will be...
