NASA has planned to build a Starshade to look for Alien Planets. Starshade exoplanet-hunting missions may be technologically daunting.
A team of scientists from Israel used quantum superfluid to test Hawking black hole theories which may have found evidence that so-called “Hawking radiation” is a real phenomenon of black holes. The effects of this study could change the way that humans understand the universe and the fate of stars.
According to www.extremetech.com “Decades ago, Hawking’s groundbreaking theoretical work on black holes set forth numerous predictions. In the intervening years, many of them have been proven accurate. Hawking radiation is one of the most interesting and mind-bending of his black hole hypotheses, but it’s been very difficult to test until now”.
Stephen Hawking said that the bizarre realities of the universe at the quantum level mean that black holes don’t last forever. [They “bleed” energy over eons and eventually evaporate. Hawking noted that from a quantum perspective, the vacuum of space is not truly empty. Pairs of virtual particles should be flashing into existence for infinitesimal slivers of time before re-combining and annihilating. A black hole, however, could disrupt that process].
About Stephen Hawking!
Stephen Hawking, cosmologist, professor, physicist, scientists and in other word “Genius”, is one of the best known and famous theoretical physicist of his time. He passed away at the age of 76.
In late 2016, he said: “Although the chance of a disaster to planet Earth in a given year may be quite low, it adds up over time, and becomes a near certainty in the next thousand or 10,000 years.” He was confident that humans would spread out into the cosmos by that time (given the chance), but added: “We will not establish self-sustaining colonies in space for at least the next hundred years, so we have to be very careful in this period.” After more recent events, Stephen Hawking described President Donald Trump’s decision to abandon the Paris Climate Agreement as “the most serious and wrong decision on climate this world has seen.”
