Robert M. Schoch, Ph.D. discussed how coronal mass ejections from the
sun unleashed discharges upon Earth which destroyed ancient advanced
cultures. Schoch declared. To that end, he noted that ancient
hieroglyphs, such as Easter Island's rongorongo script, appear to depict
plasma phenomena in the sky as observed by the denizens of Earth.
Additionally, Schoch cited ice core studies, lunar materials, and the
preponderance of ancient, seemingly abandoned, monuments as evidence for
such an event. To that end, he pointed to Turkey's Gobekli Tepe site,
which has been dated to this time frame and, he believes, was purposely
buried by its creators, as an indication that the ancients tried to
protect their civilization from the solar event.
Based on his
research, Schoch surmised that these coronal mass ejection events happen
roughly every 10,000 years and that the Earth is due to be hit again
soon. Additionally, "super energetic electrons and protons" would blast
the Earth, damaging electronics, and earthquakes as well as volcanic
activity would be induced. While Schoch dismissed the idea that the
Mayan calendar is an exact prediction of the next coronal mass ejection,
he did suggest that the infamous timetable is alluding to such an
event. Ultimately, he warned that "any time between now and the next
five years, even ten years," the planet could fall victim to the massive
solar blast.
Schoch also provided an update on his research into
the Sphinx and contended that there "absolutely something under the
left paw." He explained that seismic investigation into this anomaly
indicates that the chamber is 12 by 9 meters and theorized that there is
a cliff base beneath the sands of the Sphinx where a door likely leads
into the mysterious structure. Unfortunately, Schoch lamented that the
rising water tables in Egypt are now likely flooding the chamber, which
makes timely exploration of the find to be of paramount importance.
Connecting his Sphinx research with the study of coronal mass ejections,
Schoch speculated that the structure was contemporaneous with the
Gobekli Tepe monument and depicted a male lion which would indicate a
message, of sorts, concerning the sun.

Various
existential risks have the potential to destroy, or drastically
restrict, human civilization; could cause human extinction; or even
cause the end of Earth. Severe events could cause the extinction of all
life on the planet Earth, the destruction of the planet Earth, the
annihilation of the solar system, to the annihilation of our galaxy or
even the entire universe. Existential risks are distinguished from other
forms of risk both by their scope, affecting all of humanity, and
severity; destroying or irreversibly crippling the target.
Natural
disasters, such as supervolcanoes and asteroids, may pose existential
risks if sufficiently powerful, though man-made events could also
threaten the survival of intelligent life on Earth, like catastrophic
global warming, nuclear war, or bioterrorism.
While individual
threats, such as those posed by nuclear war or climate change, have been
intensively studied on their own, the systematic study of existential
risks did not begin until 2002.
Future scenarios
Some that
will almost certainly end life on Earth are certain to occur, but on a
very long timescale. Others are likely to happen on a shorter timescale,
but will probably not completely destroy civilization.
Some
foreseen hazards which have been excluded from the list on grounds that
they seem too unlikely to cause a global terminal disaster are: solar
flares, supernovae, black hole explosions or mergers, gamma-ray bursts,
galactic center outbursts, buildup of air pollution, gradual loss of
human fertility, and various religious doomsday scenarios.
Biotechnology
could lead to the creation of a pandemic, chemical warfare could be
taken to an extreme, nanotechnology could lead to grey goo in which
out-of-control self-replicating robots consume all living matter on
Earth while building more of themselves - in both cases, either
deliberately or by accident.
It has also been suggested that in
the pursuit of knowledge humanity might inadvertently create a device
that could destroy Earth and our solar system.
Warfare and mass destruction
The
scenarios that have been explored most frequently are nuclear warfare
and a Doomsday device. It is difficult to predict whether it would
exterminate humanity, but very certainly could alter civilizations in
the event of a nuclear winter.
Present trends of overpopulation,
economic development, and non-sustainable agriculture. Most of these
scenarios involve one or more of the following: Holocene extinction
event, scarcity of water that could lead to approximately one half of
the Earth's population being without safe drinking water, pollinator
decline, overfishing, massive deforestation, desertification, climate
change, or massive water pollution episodes
