Lambda-CDM explains very well the observations at large scales. We have tested this theory with different observables — with the cosmic microwave background, with galaxy clustering, with the Lyman-alpha forest. And all of them are in agreement with what is predicted by the Lambda-CDM standard model for cosmology. By construction, different models of dark matter [...]

Harvard Cosmologist Cora Dvorkin Dreams in Dark Matter | Quanta Magazine
The universe we can see is only a fraction of the great cosmic beyond. Galaxies, stars, planets, humans, trees — all of it comprises just 5% of the energy and matter in the universe. Among tangible matter, as opposed to the mysterious cosmic rending force called dark energy, only about 15% is the stuff we [...]
How Life Could Continue to Evolve – Issue 88: Love & Sex – Nautilus
... the ultimate currency of life in the universe may be life itself: The marvelous genetic surprises that biological and technological Darwinian experimentation can come up with given enough diversity of circumstances and time. Perhaps, in the end, our galaxy, and even our universe, is simply the test tube for a vast chemical computation exploring [...]
Consciousness Isn’t Self-Centered – Issue 82: Panpsychism – Nautilus
... how does felt experience arise out of non-sentient matter? The Australian philosopher David Chalmers famously termed this the “hard problem” of consciousness.1 Unlike the “easy problems” of explaining behavior or understanding which processes in the brain give rise to various functions, the hard problem lies in understanding why some of these physical processes have [...]
Wormholes Reveal a Way to Manipulate Black Hole Information in the Lab | Quanta Magazine
As experimental proposals go, this one certainly doesn’t lack ambition. First, take a black hole. Now make a second black hole that is quantum entangled with it, which means that anything that happens to one of the black holes will seem to have an effect on the other, regardless of how far apart they are. [...]
