minus-squareJay@lemmy.calinkfedilinkEnglisharrow-up0·2 个月前Our planet actually gets roughly 50,000 tonnes lighter every year. (We gain 40t from meteors but also lose about 90t of hydrogen.) https://www.cbc.ca/radio/quirks/sept-1-2018-gene-editing-in-dogs-wildfire-prediction-zika-fizzles-and-more-1.4804892/is-earth-getting-heavier-or-lighter-1.4804900
minus-squareHawke@lemmy.worldlinkfedilinkarrow-up0·edit-22 个月前Math does not check out. 40 - 90 = -50. Not 50,000. Edit: from the source, the correct statement is “We gain 40 000 t from meteors but also lose about 90 000 t of hydrogen.

minus-squareddash@lemmy.dbzer0.comlinkfedilinkarrow-up0·2 个月前What is heavier, one ton of meteors or one ton of hydrogen?
minus-squaresugar_in_your_tea@sh.itjust.workslinkfedilinkarrow-up0·2 个月前Only if you use imperial units. The article uses tonnes, which is a unit of mass, not weight.
minus-squareHawke@lemmy.worldlinkfedilinkarrow-up0·2 个月前Yes but I would interpret “heavy” to be a function of weight, not mass.

minus-squareDem Bosain@midwest.sociallinkfedilinkEnglisharrow-up0·2 个月前Yeah, and when you burn that fuel it gets hotter, and that makes it a little lighter too.

Depends on gravity ;-)

African or European?
