Rapid climate change is making the Earth’s atmosphere unsuitable for human life, as industrial and international pivots toward sustainable energy goals aim to secure humanity’s common future.
However, when several threats to human life occur simultaneously – such as the climate and the COVID-19 crisis – the question of long-term survival arises. We will certainly overcome the COVID-19 crisis, and the species has a good chance of overcoming long-term climate change.
But sometime – billions of years from now – the Sun will eventually destroy the Earth. A recent study published in the journal Astronomy of nature offering a view of Earth-like crusts floating around their host star system. While none of us will be around until we see the Earth reach its final stage as well, it raises the question of how humanity will survive on Earth. If he can.
Elon Musk’s two-planet species is planning for Mars
A year ago, Elon Musk published new details about his plans to colonize Mars with his aerospace company, SpaceX – suggesting that a working human presence could take seed on the Red Planet by the middle of the 21st us.
If we take Musk at his word, SpaceX is launching and dealing as a whole – from commercial rideshares and Starlink satellites to orbit on Earth, the contract from NASA to launch parts for Gateway Upcoming Lunar, to the explosive prototype Starships – united in one mission to establish a permanent human presence on Mars.
With human populations on both Earth and Mars, the species has a better chance of surviving events at an extinct level, because – inhibiting the singularity of black holes, solar flares or -usually monstrous, or a nearby supernova – such events are not yet visible on both planets at the same time.
SpaceX aims to send humans to Mars by 2026
The challenge, of course, is to develop a broad new set of engineering and technology to support humans in environments that are largely lethal to human bodies. One day we may be hitting the Red Planet – thickening and changing the atmosphere to support human life – but this could take centuries, or longer.
Nonetheless, Musk’s SpaceX has come a long way from several commercial shows each year – with 26 successful shows in 2020. But despite Musk’s bid to send humans to Mars by 2024. Or is it 2026 was it?
Titan’s moon Jupiter could host an insulated colony
Since the European Space Agency’s (ESA) Hydrogen probe hit the surface of Jupiter’s moon, Titan, researchers have considered the planet for possible colony.
Unlike the moon and Mars, any moon has the densest atmosphere in the solar system – which would act as protection from solar radiation. Oceans of methane and ethane on the Jovian moon may contain large groups of liquid hydrocarbons – potentially fuels.
Titan also contains water, as well as an abundance of natural resources – by which future astronauts could build and maintain a foundation.
Life longer than the solar system
While Venus and Europa may support small habitats – in the clouds and under the ice sheets of each body, respectively – the most effective way for people to survive local extinction events is to spread beyond our solar system.
The nearest Alpha Centauri star system is about 4.4 light years away – which means it would take almost 4.5 years to reach the system if we move at the speed of light (which is theoretically impossible). This is especially troubling since new research has emerged into a world that could sustain life in the Alpha Centauri A residential realm.
Generation vessels are very enthusiastic
Sadly, conventional methods of chemical rocket propulsion would take 19,000 to 81,000 years to reach Alpha Centauri. In addition, a study in 2019 suggested that a generational land – where humans can live and reproduce during the eons-long journey – required artificial land to grow food, and be large enough to generate artificial gravity through spinning. This could mean a minimum radius of 735 ft (224 m), and a minimum length of 1,050 ft (320 m).
Preventing such a strong and long-lasting commitment, we could also seed “plants” across the constellation with the building blocks of life – effectively compromising the survival of our species to the system. our home sun and let other life forms radically evolve. environments.
The Genesis project could ensure that life grows in other systems
Called the Genesis project, the interplanetary spawning effort would spread microbial life on “abruptly inhabited exoplanets – ie planets that are capable of sustaining life, but are unlikely to cause it. himself, “said Claudius Gros of Goethe University ‘s Institute of Theoretical Physics, according to Phys.org report.
While we still have options to help humans survive on Earth by settling other planets into our solar system, a low-cost backup plan could cost a “jump-start” evolution on planets that would not tend to develop life independently and ensure that light “consciousness,” as Musk calls it, has a chance to emerge elsewhere. Just in case we don’t live on Earth.
