Antarctic Sea Ice Is at a Record Low — Again

Posted on Categories Discover Magazine

The extent of sea ice around Antarctica has reached a record low level — for the second Southern Hemisphere summer in a row.

Now a group of astronomers have taken this question further by asking whether life could exist in other universes. In other words, they want to know whether we are alone in the multiverse.
