Miniature Black Holes Hit Earth Once Every 1000 Years!

A NASA study claims that the universe is occupied by miniature black holes or primordial black holes, which are formed during the Big Bang. Accordingly, these black holes collide with Earth once every 1,000 years.

Unlike the black holes most of us know, these ones weigh a lot less, possibly as heavy as our moon, an asteroid or even between these two. It is also possible these black holes can shrink down to only 0.25 millimeters in diameter or about the width of a human hair. Astrophysicist Timothy Brandt, from the Institute for Advanced Study, adds that some of these can have sizes less than that of an atom.

Nevertheless, Alexander Kashlinsky, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, asserts that detecting these miniature black holes when they pass through Earth is incredibly hard. Still, we could notice if one of these comes to us as evidenced by the alteration of our satellites’ orbits.

These tiny cosmic objects are also speculated to surround the whole universe. Some scientists theorize that countless small black holes actually occupy most of space instead of dark matter, which many currently presume to occupy majority of space.

“On the dark matter particle side of the spectrum, the range of possibilities is narrowing down quickly,” Kashlinsky points out. “If nothing is found there, and nothing is found in the black hole theater, then we may be in a crisis of science.”

Still, the experts assert that further research is necessary. As of now, they have not found concrete evidence that could confirm these black holes exist.

Another NASA observation of our universe reveals that it is expanding five percent to nine percent faster than assumed. Based on the space agency’s Hubble Space Telescope data, the universe expands as fast as 73.2 kilometers each second per megapersec (megapersec= 3.26 million light-years). Therefore, the distance of a cosmic object from another will double within the next 9.8 billion years.
