Quote of the Day:


The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd.

Bertrand Russell

  1. crocodile ancestor
    It walked upright? That sounds a bit misleading, since it brings to mind an image straight out of David Icke. Or maybe an old Godzilla movie. 😉

    So here’s a version of the article that has a better illustration. Clearly, it only used two legs for locomotion, but in my book, that isn’t the same as walking upright.

  2. Quantum gravity
    Glad to see scientists working on quantum theory of gravity are finally finding mathematical reasons why dark matter doesn’t need to exist.

    I’ve said on this forum before that I’ve always considered dark matter to be a cosmological “fudge factor” to account for the fact that science’s theories aren’t yet completely correct.

    yer ol’ pal,

    1. accounting issues
      Actually, from talking to a physicist friend of mine, dark matter is exactly what you say: a fudge factor introduced to make the balance in equations work. So is “dark energy”.

      There isn’t really any claim that those things have been observed. Instead, the discrepancy between predictions of the currently accepted models on the one hand, and observed measurements on the other hand, are quantified by the “dark matter” and “dark energy” terms in the equations.

  3. Earth-like Planet
    From the article…

    The vast majority of these have been gas giant planets like Jupiter, which are hostile to life as it is known on Earth.

    Ok, I had to submit this article if for no other reason, the writer actually deserves credit for promoting the concept that life might exist in the universe that is actually different than what exists on earth. If anyone here knows anything about me, it’s my rant about statements implying some spacial mass does support life. The ‘as we know it’ could always be assumed, but why assume a reader understands something when you can actively promote a concept? Ok, off my soapbox now. Though if I knew who the writer of the article was, I’d send them a nice email…
