This is how ESA telescope Euclid is going to visualize dark matter

Posted by in categories: cosmology, physics

How can you see something that’s invisible? Well, with Euclid! This future ESA telescope will map the structure of the universe and teach us more about invisible dark matter and dark energy. Scientific coordinator of Euclid and Leiden astronomer Henk Hoekstra explains how this works.

Why do we assume that exists, if we have never seen it or even measured it? “We are orbiting the centre of our galaxy at 220 kilometres per second,” says Hoeksta. A bizarre speed, which fortunately we don’t notice. Still, something strange is going on. “Based on the number of stars in our Milky Way, the stars at the edge of the Milky Way should have a much lower speed, but they move as fast as the Sun. Yet these stars are not being slung into the . Something is holding them together.”

Betelgeuse Has Finally Stopped Dimming, Says Astronomer

Posted by in category: cosmology

Betelgeuse has been acting strangely, but don’t expect any fireworks in the next 100,000 years; rumors of a pending supernova have all been overhyped.

The CIA Admits Psychic Abilities Are Real, But Cannot Figure Out The Science Behind It

Posted by in categories: cosmology, quantum physics, science

According to a CIA document declassified on 08/07/2000 titled “Coordinate Remote Viewing (CRV) Technology 1981–1983,” submitted to the organization August 4 of 1983, coordinate remote viewing “utilized through the methodologies that have been developed…works with remarkable precision,” but the individuals who submitted it admitted that they were “unable to explain in conventional terms why it is that the co-ordinate serves as a stimulus in the manner it does.” Nevertheless, they were convinced that David Bohm’s model of quantum mechanics provided a potentially plausible explanatory hypothesis for the mechanisms that make it possible.

David Bohm was a controversial yet brilliant luminary in physics who argued that the entirety of the cosmos is populated with quantum black holes that lead from the “explicate order” of spacetime to a realm that transcends space and time which he referred to as the “implicate order.” These black holes were termed “holospheres,” and hypothesized as the mechanism which connects the implicate order to the explicate order. From the perspective of the remote viewer, it is possible that the signal line we acquire is mediated by these holospheres, which connects us with an implicate order that is conceptually more or less identical to the Eastern concept of “Akasha” or the “Akashic records,” as articulated in the work of writers such as Swami Vivekananda.
