  • It doesn’t make sense that we couldn’t see it and the particles that could explain it seemed like they were invented just to justify dark matter

    It always seemed like a natural assumption to me: the particles we know about were discovered because they interact with each other via at least one other force in addition to gravity. But there’s no other force common to all particles, so why not expect particles that only interact via gravity? They’d naturally be hard to detect, since gravity is so much weaker than the other forces.

    Assuming that the only particles that exist are the ones that happen to be easy for us to detect feels like observer bias.










  • When Heggarty’s team reran the analysis with this new database, their findings broadly agreed with the earlier, farmer-origin theory, locating the origin squarely in Anatolia about 8,000 years ago. From there, some branches of the language moved eastward and gave rise to languages including Persian and Hindustani. Other branches moved west to eventually develop into Greek and Albanian. But the analysis also recognizes the steppes as playing an important role as a secondary homeland for most European languages: After one branch traveled northward from Anatolia to the steppes, it radiated from there into northern Europe, giving birth to Germanic, Italic, Gaelic, and other European language families.

    Wait, this theory implies that the Iranian languages (including Scythian, Sarmatian, and Saka as well as Persian) were not part of the steppe pastoralist branch?
