lol a material that dense and that small would just blow up

    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?

    NASA originally published that it was around 1000 pounds and two feet across. Then Jpost sensationalized it. A ball of iron that size would be about 1800 pounds.

    how is that possible, isnt the densest element like 22g/cm^3? i dont know how much 3 baby elephants weight but its definitely more

    Obvious product placement by the baby elephant lobby

    I'm confused.

    Not from the mass or size.

    But from exactly what it is doing to Mars?

    Product placement getting the bills paid without being excessively obnoxious--rare.

    Yesterday I searched for how much an acre is, only to find this: https://www.wagrown.com/what-does-an-acre-look-like

    1,584 potatoes
    The amount of potatoes needed to make a line from one end to the other end of an acre.

    And Wikipedia made it sound even funnier to me: https://en.wikipedia.org/wiki/Acre

    It is traditionally defined as the area of one chain by one furlong (66 by 660 feet), which is exactly equal to 10 square chains, 1⁄640 of a square mile, 4,840 square yards, or 43,560 square feet, and approximately 4,047 m2, or about 40% of a hectare.

    Or with rods: https://en.wikipedia.org/wiki/Rod_(unit)

    The 'perfect acre' is a rectangular area of 43,560 square feet, bounded by sides 660 feet (a furlong) long and 66 feet (a chain) wide (220 yards by 22 yards) or, equivalently, 40 rods by 4 rods. An acre is therefore 160 square rods or 10 square chains.

    If you've ever played or watched cricket, which is a very imperial kind of game, then the pitch (the distance between the wickets) is exactly one chain, and the field (the whole playing ground) is typically one acre although it isn't standardised.

    Cricket ball is leather, about the size of your fist, and surprisingly heavy. A chain is about as far as you can throw such a ball over-arm, and an acre is about the circle of how far you can smack such a ball with a bat before it touches the ground.

    heavy would imply weight wouldn't it? if they are all in orbit wouldn't 10,000 baby elephants weigh the same as 3, the same weight as a football field, or an Olympic sized swimming pool, and the same as a single can of Dr Pepper?

    It could also imply mass which doesn't change regardless of gravity.

    Also being in orbit doesn't significantly reduce the amount of gravity impacting the object. The reason astronauts feel weightless is because bring in orbit means they are moving fast enough to keep missing the object they are orbiting. So it isn't a lack of gravity, it is constant free fall.

    I use metric to hold papers down on my desk.

    If I have 10 papers, I add another metric.

    It's not "Meteor the size of a Dr Pepper" but "A meteor The size of Dr Pepper" as in the whole company.

    So, 12oz can contains 355mL, which is 355cm^3

    Okay so how much force is 3 baby elephants?

    Yes, I’d try to estimate the density.

    Most people probably know how big a pop can is, and understand that even baby elephants are pretty heavy. It gets the point across better than "A meteor with a volume of approximately one third of a litre and a mass of approximately 350 kilograms".

    But it's so ludicrous it doesn't pass even the most basic smell test.

    What's a baby elephant weight? 100lbs., right out my butt. (Google says 200 at birth.) You can't pack 300lbs. of anything into a pop can. Nothing in this solar system.

    No.

    33cm3 and 350kg would be much better.

    Shows how American you are if you think baby elephants is better.

    Metric is scientific, media units are relatable. 355 CC's with a mass of roughly 360 kgs is hardly easy to visualize compared to 3 elephants on a scale next to a can of Dr Pepper.

    Metric is perfectly relatable for anyone growing up using it. This is just you outing yourself as USAmerican.

    P.S. We would use Litres, which everyone has a concept of (Everyone has seen a 1 litre carton of milk) and is easily converted to/ from cubic cm (1000 cm^3 = 1 L = 1000 mL).

    Y’all failed to realize that Americans are math, science, and just regular plain sorts of illiterate. So if you want them to understand anything, you have to give it to them in units they can physically see or common household objects.

    Just think of it as trying to explain a difficult concept to a toddler or maybe at best a six-year-old. That’s what it feels like talking to the American public.

    That would be a density of over 750 g/cm³, more than 20 times denser than Osmium, the denset known material (outside extreme gravity wells)

    Somebody messed up their arithmetic. Three baby elephants weight roughly 800 lbs. To weigh that much, an object the size of a soda can would have to be composed of extremely dense matter, like from the interior of a star.

  • source
  • [–] 5 points 2 weeks ago

    Yeah no they didn't. Not unless it's the world's smallest neutron star.

    Seriously even if you don't know a thing about science, all you have to do is look at those numbers and you can intuit that they don't work.

    Even if it were composed entirely of osmium, it would have that mass.
