While the event is generally held to have been caused by a meteor air burst, several alternative explanations have been proposed both in scientific circles and in fiction. [ 3 ] [ 4 ] [ 5 ] A popular one in fiction is that it was caused by an alien spaceship , possibly first put forth in Ed Earl Repp 's 1930 short story " The Second Missile ".
It is based on the theory that the Tunguska event was caused by a micro black hole. [4] Trying to locate weapon of mass destruction, Marianna Bonaventure is an American in the United States Department of Energy's CROM (Critical Resources Oversight Mandate) who has to work together with the outstanding analyst Jonathan Knox.
Another proposed explanation is that the cause was the impact of a micro black hole, as in Larry Niven's 1975 short story "The Borderland of Sol". [11] Some stories nevertheless accept the conventional meteorite explanation, such as the 1996 The X-Files episode " Tunguska " that instead revolves around the impact possibly having introduced ...
One of the best-known recorded impacts in modern times was the Tunguska event, which occurred in Siberia, Russia, in 1908. [85] This incident involved an explosion that was probably caused by the airburst of an asteroid or comet 5 to 10 km (3.1 to 6.2 mi) above the Earth's surface, felling an estimated 80 million trees over 2,150 km 2 (830 sq mi).
For example, the Tunguska event of 1908 is believed to have resulted from a meteor air burst. [4] Black hole mergers, likely involving binary black hole systems, are capable of radiating many solar masses of energy into the universe in a fraction of a second, in the form of a gravitational wave.
Asteroid 2024 YR4 has a 1.3% chance of impacting Earth in 2032, NASA reports. Astronomers all over the world are watching the asteroid, trying to narrow down its future path.
A verneshot has been proposed as an alternate explanation for the Tunguska event, widely regarded as the result of an atmospheric explosion of a small comet or asteroid.. Arguments offered for this mechanism include the lack of extraterrestrial material at the event site, the lack of a credible impact structure, and the presence of shocked quartz in surface outcrops.
