No, they didn't (part 3)

It was about time for more bullshit sensationalist "science" headlines. This time people are geeking out over the possibility that a science experiment in Antarctica detected "evidence" of a parallel universe where time runs backward.

Of course they didn't.

The latest Internet frenzy comes to you via this article from NewScientist.com with the headline, "We may have spotted a parallel universe going backwards in time". Other news outlets dropped the "may" from their headlines and simply reported it as "fact". You can thank sloppy headline writers for the hype... again. Which gives me the opportunity to pull out this graphic one more time, and award it to all the media outlets that have copied it from one another without the slightest effort toward critical analysis.

The source of the data is the Antarctic Impulsive
Transient Antenna (ANITA), a NASA-sponsored balloon experiment. You can read the report here [PDF]. The report details four anomalous particle detections over the years, the results of neutrino collisions. A problem with these detections is that they appear to have originated from the direction of the Earth, which would be unlikely given the way these are known to originate. Note, please, the word unlikely. Note that it does not mean "impossible". Rather, it hints at a possibility. It is possible, for example, that the readings were erroneous. It is possible that the current models are not accurate. It is possible that some other factors, as yet unknown, were involved. For instance, while the polarity is inconsistent with a reflection, multiple reflections, as unlikely as they may be, may account for it. It is possible that, as unlikely as it may be, the detected neutrinos made it through the Earth. It is also possible that a very unlikely hitherto unobserved event did in fact occur.

What is less likely than any of those possibilities is that the readings have revealed a hitherto-unknown entire universe, along with evidence of how the laws of nature operate in same. There is no evidence that there is a universe where left is right, up is down, and time is reversed. While in the right hands these may become hypotheses, as reported they are speculations and fantasies. Not evidence. At the moment what we have is four readings in need of explanation.

Let me be clear, though... the NASA report is not at fault. The authors are exceedingly clear about what they discovered. They don't say what it is; rather, they say what it's unlikely to be, and why they think that. And as they state in the report, "Current or future data may be able to confirm or falsify whether neutrino interactions are the origin of this event." These are scientists, not click-mongers and sensationalists.

In case you've forgotten previous hype, the following once-major headlines are also bullshit:
  • Scientists have discovered cold fusion
  • Study finds scientific reproducibility does not equate to scientific truth
  • Bristol academic cracks Voynich code
  • Satnavs ‘switch off’ part of the brain we use for navigation
However, one headline that is decidedly not bullshit is this:


Keep calm and carry on. Your life hasn't changed after all.
