This is how the world ends: will we soon see category 6 hurricanes?

Posted by in categories: climatology, mathematics

Not the end, but interesting… Also, note that hupercanes are possible products of some mathematical instability, where the speed start to grow almost unlimited after some threshold. Buts Cat 6 is not a hypercane, as in the hypercane winds will be 500 mph.


There is no such thing as a category 6 hurricane or tropical storm — yet. But a combination of warmer oceans and more water in the atmosphere could make the devastation of 2017 pale in comparison .

The universe is a big place, so when we get beautiful images from NASA’s Hubble Space Telescope, they cover a very small spot in the sky that may not fully represent what the universe at large looks like

The universe is a big place, so when we get beautiful images from NASA’s Hubble Space Telescope, they cover a very small spot in the sky that may not fully represent what the universe at large looks like. To change that, we’re expanding our view by significantly enlarging the area covered around huge galaxy clusters previously seen to get a better look at the universe.

Scientists Say We Can’t Terraform Mars. Elon Musk Says We Can

Posted by in categories: biotech/medical, Elon Musk, engineering, environmental, space

SpaceX’s CEO shrugs off 20 years of NASA research.


SORRY, ELON. To be ready for human occupants, Elon Musk has long called Mars a “fixer-upper of a planet.” But according to a new NASA-sponsored study, a better description might be a “tear-down.” The scientists behind that project say it’s simply not possible to terraform Mars — that is, change its environment so that humans can live there without life support systems — using today’s technology.

BUILDING AN ATMOSPHERE. Mars has a super thin atmosphere; a human unprotected on the surface of Mars would quickly die, mostly because there’s not enough atmospheric pressure to prevent all your organs from rupturing out of your body (if you survived a little longer, you could also suffocate from lack of oxygen, freeze from low temperatures, or get fried from too much ultraviolet radiation).
