      True, quick math that’s 4225x heavier than pure uranium, but still 666x lighter than neutron star soup. No material holds together at that density without a stars worth of gravity

        Sorry, I’m having trouble understanding. Could you express that in approximate number of cans of Dr. Pepper?

          Say you had a year’s* worth of Dr. Pepper supplies jam-packed into a single can of Dr. Pepper.

          * approximate values assuming 3 servings a day

          you need the gravity of a star like Taylor Swift to hold a mass as small as Marco Rubio but as dense as R.F. Kennedy Jr.

          It’s the size of a dr. Pepper and the weight of 3 baby elephants.

          It’s also the size of a baby elephant foot and the weight of 728 cans of dr. Pepper.

            That’s fine and dandy, but what I really wanna know now is, to the size of how many Dr. Pepper cans can I compress 3 baby elephants and have that hold together?

            • 3 baby elephants, each about 100 kg is 300 kilogram. Round to density of water, so say 300 liter and ignore the chunks. One can is 0.355 liter. Round to ⅓ liter. That makes 900 cans. About one pallet low stacked pallet.

                Thanks for spelling that out, but maybe I need to be more specific about the assignment. In your example the elephants still consist of elephant matter. I wanna know what happens, if we’re allowed to change that on a nuclear level, so shift some protons, neutrons (and whatever other particles, that I know nothing about) around. How many Dr. Pepper cans is the currently known limit of physics here?

                • Say we change the mass of elephants to osmium. That’s 41 liter or 123 cans. That fills up about half of the bottom of a pallet.

                  Say we chuck the elephants into Jupiter and let them sink to the core. That’s 27 liter or 80 cans. Roughly 3 cardboard trays of 24 cans each.

                  Say we chuck the elephants into the center of the sun. That’s 2 liter or 6 cans, so a six-pack.

                  If you use exotic matter things get silly. You’re not talking about cans anymore. 300 kilograms of neutronium is barey a micrometer in size. Black hole matter is smaller than a proton.

        Somethings amiss here, the article talks about a meteorite that broke up in earths atmosphere, and above there’s talk about mars

          The meme is fake. It’s one of those “breaking news” generated images and the “Channel 23” logo is just slapped on.
