• What Came Before the Big Bang?
    The two things that I’m always curious about space/time is whether we live in a simulation, and what happened before the Big Bang. Here are 3 ideas on the latter.

    A second major hypothesis is that the universe, and time, did not exist before the Big Bang. The universe materialized literally out of nothing, at a tiny but finite size, and expanded thereafter. There were no moments before the moment of smallest size because there was no “before.” Likewise, there was no “creation” of the universe, since that concept implies action in time. Even to say that the universe “materialized” is somewhat misleading. As Hawking describes it, the universe “would be neither created nor destroyed. It would just BE.” Such notions as existence and being in the absence of time are not fathomable within our limited human experience. We don’t even have language to describe them. Nearly every sentence we utter has some notion of “before” and “after.”

  • How Big Business Got Brazil Hooked on Junk Food
    Junk food is not all bad. If it wasn’t for junk food, a lot of people in Brazil would be starving as they would not be able to buy enough food to sustain themselves. Yet is surviving on junk food any better?

    Ms. de Vasconcellos has diabetes and high blood pressure. Her 17-year-old daughter, who weighs more than 250 pounds, has hypertension and polycystic ovary syndrome, a hormonal disorder strongly linked to obesity. Many other relatives have one or more ailments often associated with poor diets: her mother and two sisters (diabetes and hypertension), and her husband (hypertension.) Her father died three years ago after losing his feet to gangrene, a complication of diabetes.

    “Every time I go to the public health clinic, the line for diabetics is out the door,” she said. “You’d be hard pressed to find a family here that doesn’t have it.”

  • The Untold Story of Kim Jong-nam’s Assassination
    The real life assassination of a North Korean leader is almost unbelievable (as with many things North Korea), but someone has done a lot of leg work to try and get a detailed story of what happened.

    The liquid that Siti rubbed on Jong-nam’s face was likely not true VX. Experts have suggested that a modified version of normal VX—VX2—was employed instead. As Vipin Narang, a professor of political science at MIT who holds two degrees in chemical engineering, explained to me, “VX2 is made by dividing VX into two nonreactive compounds. What the women were likely doing was creating active VX on Jong-nam’s face by each delivering their ingredient.”

    This complicated method of poisoning Jong-nam would have had several advantages. First, the toxin would have been safe until activated. Even then, VX2 is not very volatile compared with other chemical weapons, meaning it was less likely to affect bystanders or first responders. If VX2 was employed, it’s unlikely Siti would have been affected, as striking first she never would have been exposed to the second reactant.

  • Valve is not your friend, and Steam is not healthy for gaming
    I never liked Steam as a store or a service. The software just seemed clunky and unnecessary and I’m not even a gamer so I can imagine what people who use it every day would think. This story is biased as the author has a big beef with it, but it also lists out a bunch of things wrong with the service

    Valve themselves eagerly trumpeted that they had paid more than $57 million to Steam Workshop creators over four years — an enormously impressive figure until you realize that it’s only 25 percent of the sale price, which means Valve just made $171 million profit from … setting up an online form where you can submit finished 3D models.

  • Where are all the aliens?
    This article talks about the Fermi paradox (if there are so many stars, why can’t we find other intelligent species?) and lists a bunch of reasons why it may exist. It’s a primer article on the paradox and I felt I’ve read it somewhere else before, but it’s still interesting.

    Possibility 5) There’s only one instance of higher-intelligent life—a “superpredator” civilization (like humans are here on Earth)—who is far more advanced than everyone else and keeps it that way by exterminating any intelligent civilization once they get past a certain level. This would suck. The way it might work is that it’s an inefficient use of resources to exterminate all emerging intelligences, maybe because most die out on their own. But past a certain point, the super beings make their move—because to them, an emerging intelligent species becomes like a virus as it starts to grow and spread. This theory suggests that whoever was the first in the galaxy to reach intelligence won, and now no one else has a chance. This would explain the lack of activity out there because it would keep the number of super-intelligent civilizations to just one.
