As physicist Michio Kaku puts it in his article on Big Think, ‘Forget Alien invasion—space junk is the real menace from space.’ The aftermath of the past fifty years of launching to a height as low as low earth orbit—and, of course, beyond—has been the end of the dreams of the famed minds who saw space as the ultimate dumping ground. As it turns out, even physicists now have a problem when it comes to sending things off to faraway places: they need to dodge the space junk floating around the earth much like a satellite (which is supposed to be there anyway.)
Now our problems do not end there.
