When Asteroid Impacts Are a Good Thing

Posted by in categories: asteroid/comet impacts, existential risks

Meteorite impacts may be a good thing — but only sometimes.

Craters could create habitable conditions on many planets and moons.

Study: More Than 500 Vertebrates Poised To Go Extinct

Posted by in categories: biotech/medical, existential risks

We should save their DNA and resurrect them or keep in a bubble environment.

Close To Home

The researchers behind the study warned that each time an animal goes extinct, it also threatens humanity’s continued survival.

Black hole “crystals” as seeds of structure formation in the early Universe

Posted by in categories: cosmology, existential risks, particle physics

Circa 1994

It is generally accepted that structure formed in the matter dominated Universe, for obvious reasons. In this paper, we would like to suggest an alternate theory: that structure could have formed in the radiation dominated Universe if it was “protected” from destruction. This protection is envisioned as a “crystal”, of sorts, made up of primordial black holes (PBH’s), which form a cavitation into which any matter particles in the nucleosynthesis period of the Universe (around 100 seconds after the Big Bang) could have taken refuge. A sort of oasis in a sea of radiation. Such a scenario could solve several problems in cosmology, namely: how matter got a foot-hold over anti-matter in the Universe; the structure/galaxy formation problem; and possibly suggest ideas on the gamma-ray count and distribution.

#SpaceWatchGL Opinion: Satellite Technologies Use To Monitor Climate Change and Manage Environmental Disasters

Posted by in categories: climatology, economics, existential risks, habitats, satellites, sustainability

The recent 2020 US West Coast wildfire has opened infernos, as it ravaged hundreds of homes and charred hundreds of neighborhoods. On September 10, 2020, CNN announced that the Creek Fire had taken more than 166,00 acres after destroying 360 structures in Central California, Amidst a state emergency, firefighters had to defeat the “beast” that turned the scenery to a similar fiction movies scene on a doomsday. Wildfire causes environmental disasters that were attributed by many scientists to climate change. The preparedness, detection, and management of wildfires and other environmental disasters, that affected the environment hinge on satellite technologies, essentially, the Remote Sensing of sea surfaces and land areas, and the civil space-based Earth Observation and its applications. Such space-based technologies are deployed to assess, monitor, and manage local, regional, and large-scale transboundary environmental issues that impact the societies, economies, and ecosystems. Thanks to its large areas’ data collection and high-frequency capabilities Earth Observation, in particular, has become a powerful tool to monitor the terrestrial environment and manage environmental disasters as it be addressed in this article.

Satellite technologies have been used to understand climate change better to find solutions to mitigate its deteriorating consequences, such as hurricanes, droughts, rising sea levels, melting polar ice caps, wildfire, and floods. Scientists relied upon various observation systems and satellite technologies, networks of weather balloons, buoys, and thermometer, to collect climate change’s evidence from the depths of the oceans to the top of Earth’s atmosphere. For instance, EO is relied upon to map the greenhouse gases. Earth Observation (EO) monitors the carbon dioxide (CO2) concentration, the second most abundant greenhouse gas component after water vapor, satellite monitored through water management, and weather forecast [1]. Public and private entities harnessed spectroscopy and satellites to monitor externalities data from various sources.

NASA warns newly-spotted asteroid to pass by ‘closer than a weather satellite’

Posted by in categories: asteroid/comet impacts, existential risks

US space agency NASA has forecast a recently-spotted asteroid, 2020 SW, for a fly-by on Thursday. It will fly by at an agonising distance of around 17,000 miles – closer than a weather satellite.

World War III will be fought over water

Posted by in categories: existential risks, finance, food, law, terrorism

RS: The third world war is at our gate, and it will be about water, if we don’t do something about this crisis. These walks are to raise awareness—this year we covered 17 countries, and in nine of them there were displaced people. So many people in the Middle East and African countries are moving to places like Europe, in part because of water scarcity—after forced migration comes, tension, conflict, and terrorism. Where terrorism is active, there is usually a scarcity of water. Look at Syria—a long time ago, it had very good agriculture, but then Turkey built a dam that changed things. It’s a similar story with Libya. If we want a safe future, we need to start conserving water.

What role can regulation play in conservation? Do you think privatizing water is a good way to promote its efficient use?

RS: If we really think about legal changes, we have to first think about river rights, or the rights of nature, and only then about water rights for humans. This type of thinking doesn’t exist today but we need this kind of legal framework that assures that the land of the river is only for the river, that the flow of the river is kept clean, and that the river has greenery on both banks to prevent erosion and silting. Only with all these factors can we ensure that rivers are healthy and only then that we are healthy.
