Dark Energy Explained | Cosmology 101 Episode 8

There is something very, very strange happening to our universe. Some mysterious force—dark energy—has taken control of the cosmos, driving distant galaxies to move in ways that challenge our understanding of fundamental physics.

We can't see it, we don't know what it is, and we’re not even sure how it can exist, yet it makes up about 70% of the universe, and it's growing.

Join Katie Mack, Perimeter Institute’s Hawking Chair in Cosmology and Science Communication, as she unravels the enigma of dark energy in this episode of Cosmology 101.

Perimeter Institute scores again. I have a doctorate and have been studying this for several years. Ms Mack does a nice job of putting dark energy where we feel it should be.

What IF....we look outside beyond the mere field of Physics and include all knowledge which happens to be structured within consciousness ( bold initial premise ). With an evolving and expanding Universe of presumably countless, intelligent, advanced living organisms that are also evolving and accelerating in their understanding of the cosmos. How does this evolution of maybe infinite number of beings inhabiting limitless space manifest ? Perhaps it manifests as an expanding Universe in which the observing conscious entities, including humans, expand their consciousness. Now most Physicists reading this will cringe with such non-mathematical expressions being used with non quantifiable words and the problem is that those Physicists need to experience the Universe within ( more cringing ) and the cringing is an initial step int he discovery of the Cosmos that is within and without. Maybe and topological strange loop like an n-dimensional Klein bottle where inside and outside are the same might be a crude example of what mind may look like to them. So perhaps what is perceived as the unexplained Dark Mass and Dark Energy is in fact the Unconscious aspect of the Universal Mind of Cosmos which includes every one of us on Earth as well as less intelligent but necessary animals, insects etc on the Great Chain of Being on our planet. So as imperfect as this is, having made this draft in about a quarter of an hour, I will stop. One reference on You Tube that might be worth watching is that of a Physicist brave enough to start exploring this and making it public - that brave Soul ( metaphor ) may be found here : Simple Technique to Connect with Pure Conscious Awareness | Rupert Spira . There are similar methophors to be found in Torah; Bible, Kabbalah Vedas of India; Sufi Mysticism, Bahai and in particular The Heart Sutra and Buddhist Sutra of Buddhism. May you find that the Inner and Outer Universe are One and it is a Conscious One. Happy exploring. Finally thanks to the presenters of this video. May Peace and Love prevail on a very conflicted Earth. Namaskar, Namaste, Amen.

We are as ants in the grass who assume that it represents the entire universe. Or maybe we are closer to bacteria in stool.

We need new ideas that don't violate conservation of energy
