“This is bigger than just Trump. This is about the DNA of our country. This is about the systematic racism and sexism that still exists every day. This is about Trump preying on the fears of the “Other.” And all of these visceral feelings are bubbling to the top as his supporters show us on a daily basis.”
“We need to continue to use our voices on social media, and in peaceful, non-violent ways, to remind the world that our country is about inclusion, and that we do not share Trump’s intolerance and hatred. America is NOT one nationality, one race, or one religion. America is a diverse mix of backgrounds, religions, races, sexual orientations, and ethnicities. That’s what makes our country great.”
This tiny ball provides evidence that the universe will expand forever. Measuring slightly over one tenth of a millimeter, the ball moves toward a smooth plate in response to energy fluctuations in the vacuum of empty space. The attraction is known as the Casimir Effect, named for its discoverer, who, 55 years ago, was trying to understand why fluids like mayonnaise move so slowly. Today, evidence indicates that most of the energy density in the universe is in an unknown form dubbed dark energy. The form and genesis of dark energy is almost completely unknown, but postulated as related to vacuum fluctuations similar to the Casimir Effect but generated somehow by space itself. This vast and mysterious dark energy appears to gravitationally repel all matter and hence will likely cause the universe to expand forever. Understanding vacuum energy is on the forefront of research not only to better understand our universe but also for stopping micro-mechanical machine parts from sticking together.
