Scientists call it the doomsday glacier.
That’s partly because the Thwaites, a Britain-sized glacier in western Antarctica, is melting at an alarming rate: It’s retreating by about half a mile (2,625 feet) per year. Scientists estimate the glacier will lose all of its ice in about 200 to 600 years. When it does, it will raise sea levels by about 1.6-2 feet.
But the sea-level rise wouldn’t stop there. Thwaites’ nickname stems mostly from what would happen after it melts. Right now, the glacier …

No one has yet managed to travel through time at least to our knowledge but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.
As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in th…

We Finally Know How Much Radiation There Is on The Moon, And It’s Not Great News – ScienceAlert

As the US prepares to return humans to the Moon this decade, one of the biggest dangers future astronauts will face is space radiation that can cause lasting health effects, from cataracts to cancer and neurodegenerative diseases.​

As the US prepares to return humans to the Moon this decade, one of the biggest dangers future astronauts will face is space radiation that can cause lasting health effects, from cataracts to cancer and neurodegenerative diseases.
Though the Apollo missions of the 1960s and 1970s proved it was safe for people to spend a few days on the lunar surface, NASA did not take daily radiation measurements that would help scientists quantify just how long crews could stay.
This question was resolved Fri…
