    1 trillion grams per second

    There must be a better way to say this

      I assume you mean one octillion of femtograms?

      I guess one billion kilograms doesn’t sound as cool?

        one billion kilograms has the same problem - it is ambiguous, because you have to guess whether you are using short or long scale.

        you could say million tonnes, but ton is not SI unit and is again ambiguous, because there is many different tonnes.

        correct presentation that isn’t open to interpretation is 1 x 109 kilograms.

          I mean, if it is spelled tonne then it is the metric unit of 1000 kilograms. Metric is also not necessarily synonymous with SI units. Celsius is another example of that.

    Source for this article, which includes the preprint, why don’t they include these in articles anymore, dammit.

    To give a sense of the phenomenon’s speed, it’s shrinking almost as fast as NASA’s earth science budget.
