![]() The result could present a challenge to basic theories of dark matter.Īnother explanation for how space acquires energy comes from the quantum theory of matter. This image shows the distribution of dark matter, galaxies, and hot gas in the core of the merging galaxy cluster Abell 520. Come to think of it, maybe it shouldn't be called "normal" matter at all, since it is such a small fraction of the universe. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe. It turns out that roughly 68% of the universe is dark energy. Other than that, it is a complete mystery. We know how much dark energy there is because we know how it affects the universe's expansion. Theorists still don't know what the correct explanation is, but they have given the solution a name. ![]() Maybe there is something wrong with Einstein's theory of gravity and a new theory could include some kind of field that creates this cosmic acceleration. Maybe it was a result of a long-discarded version of Einstein's theory of gravity, one that contained what was called a "cosmological constant." Maybe there was some strange kind of energy-fluid that filled space. But something was causing it.Įventually theorists came up with three sorts of explanations. No one expected this, no one knew how to explain it. So the expansion of the universe has not been slowing due to gravity, as everyone thought, it has been accelerating. Then came 1998 and the Hubble Space Telescope (HST) observations of very distant supernovae that showed that, a long time ago, the universe was actually expanding more slowly than it is today. The universe is full of matter and the attractive force of gravity pulls all matter together. ![]() Granted, the slowing had not been observed, but, theoretically, the universe had to slow. ![]() It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. Shot with soft light and draped in Millennial pink, the world projects a bubblegum vibe, sweetly smiling while stripping citizens of their autonomy.In the early 1990s, one thing was fairly certain about the expansion of the universe. The episode was penned by Michael Schur (“The Good Place”) and Rashida Jones (“The Office”) and directed by Joe Wright (“Pride & Prejudice”). “Nosedive” brought in big name Hollywood talent to kick off its first season on Netflix. Plus, the angrier Lacie gets about her situation, the lower she’s ranked by those she interacts with, creating a self-fulfilling spiral of social media exile. What starts off an an annoyance (can’t open certain doors) spirals into something more ominous and even life-threatening for others. But after a series of unfortunate incidents, her rank starts to slip. Bryce Dallas Howard plays Lacie, an amiable citizen with an above-average social media ranking. ![]() Set in a near future where a large percentage of the population has adopted a form of social-media eye implant that ranks people like Yelp reviews, this pastel meditation shows what happens when we allow fictional clout to dictate societal norms. Honorable mentions: “ Fifteen Million Merits,” “Be Right Back,” “Shut Up and Dance” and “Black Museum.” In celebration of Season 6, here are the 10 best episodes of the series, ranked. Season 6 ups the star power with Salma Hayek, Michael Cera, Aaron Paul and Kate Mara.Īs social media, artificial intelligence and technology still have a hold over our world, “Black Mirror” seems more relevant than ever. Several big-name stars got an early break on the series, like Daniel Kaluuya, Jodie Whittaker and Letitia Wright, while later episodes spotlighted actors like Jon Hamm, Miley Cyrus, Will Poulter and more. One hallmark of “Black Mirror” is its cast. Each standalone story revolves around some kind of near-future technology, dystopian future or cultural obsession that wreaks havoc on characters’ lives, usually to a twisty, violent ending - with some exceptions! Almost every episode ends in tragedy, heartbreak or brutal death for the cast, but some, like “Hang the DJ” and “San Junipero,” end things on a lighter note. With Season 6, fans of bleak, sci-fi drama and twist endings will get five more episodes to entertain themselves.Ĭharlie Brooker created “Black Mirror” and has written almost every episode by himself, with some help along the way. Originally conceived as an anthology program on the British outlet Channel 4, “Black Mirror” moved to Netflix starting with Season 3 and has released 22 episodes and one film so far. “Black Mirror” has shocked, creeped out and warned audiences of the dangers of technology for more than a decade, and it’s returning with Season 6 on Netflix on June 15 after a four-year wait. ![]()
