Can we make Mars Earth-like through terraforming?

Posted by in categories: engineering, environmental, space

đŸŽ”đŸŽ¶â€ŠMars ain’t the kind of place to raise your kidsâ€ŠđŸŽ”đŸŽ¶ Even then, since Mars has 38% of Earth’s gravity, it can only retain an atmosphere of about 0.38 bar.


These are some of the most compelling ideas on how to terraform Mars into a habitable, Earth-like world for future explorers.

Scientists propose theory to resolve time travel paradox and make time travel possible

Posted by in categories: mathematics, physics, space, time travel

A new theory suggests time travel might be possible without creating paradoxes.

TL;DR:

A physics student from the University of Queensland, Germain Tobar, has developed a groundbreaking theory that could make time travel possible without creating paradoxes. Tobar’s calculations suggest that space-time can adjust itself to avoid inconsistencies, meaning that even if a time traveler were to change the past, the universe would correct itself to prevent any disruptions to the timeline. This theory offers a new perspective on time loops and free will, aligning with Einstein’s predictions. While the math is sound, actual time travel remains a distant possibility.

NASA’s DART: Crashing Into Discovery With World’s First Planetary Defense Test

Posted by in categories: futurism, space

Following NASA ’s DART mission, which successfully tested asteroid deflection techniques by colliding with the moonlet Dimorphos, extensive research has revealed insights into the geological features and evolutionary history of the Didymos asteroid system.

Studies have characterized the surface and interior of these celestial bodies, examined their formation processes, and assessed their response to impacts. These findings not only provide a clearer understanding of binary asteroid systems but also enhance planetary defense strategies.

A Look at Tesla’s 4680 Gen 2 Battery Cell

Posted by in categories: energy, space, sustainability

Right off the bat, one of the biggest improvements is the weight of the 4,680 shell itself – down to 49g from the 70g weight of a gen 1 cell. Tesla has essentially optimized the shell, making it thinner, and reducing its internal complexity. They do this by welding the tabless electrode to the cell cap.

That weight reduction is significant – at the battery pack level, the Cybertruck has 1,344 cells – which means that it reduces 28.2kg or 62.1lb of the overall pack weight. But rather than leaving that space empty, Tesla has instead filled that weight with more battery material. Calculated, that’s about a 10% increase in overall pack energy density.

Using sound to measure wind speeds on Mars

Posted by in categories: futurism, space

“By measuring sound travel time differences both forward and backward, we can accurately measure wind in three dimensions,” said Dr. Robert White.


The planet Mars has several similarities with Earth, including extinct volcanoes, dry lake beds, and active dust storms, the last of which is governed by the Red Planet’s prevailing winds. However, given the average surface pressure of Mars is 0.6 percent of Earth’s due to Mars’ paper-thin atmosphere, which means the wind speeds are far smaller than on Earth. But can we accurately measure this wind speed and how will it contribute to future missions to the Red Planet?

This is what a recent study published in the Journal of the Acoustical Society of America hopes to address as a team of researchers investigated using sound to measure wind speeds on Mars, which holds the potential to help scientists better understand the various processes that comprise the Red Planet and how these processes could influence future missions, as well.

Everything in the Universe—Even Aliens—May Share a Form of Consciousness, Scientists Say

Posted by in category: space

“Certainly,” says Christof Koch, Ph.D., a neuroscientist and prominent figure in the field of consciousness studies. “Any complex system, whether evolved on Earth or elsewhere, could be conscious.” What that consciousness might look like is another matter entirely. Could aliens exhibit empathy, self-awareness, love, hate, or fear?

To answer these questions, consider panpsychism, an ancient cosmic theory that suggests consciousness could be a ubiquitous feature of the universe, akin to gravity or charge. This idea, dating back to ancient Greek philosophers like Thales and Plato, has seen a resurgence in the 21st century as mainstream scientific approaches struggle to fully explain consciousness.

Astronomers identify more than one thousand new star cluster candidates

Posted by in category: space

By analyzing the images obtained with the James Webb Space Telescope (JWST), an international team of astronomers has managed to identify more than 1,000 new star cluster candidates in the Cigar Galaxy. The finding was reported in a research paper published August 8 on the pre-print server arXiv.

An ocean’s worth of water may be hiding under Mars’ red dusty surface, study suggests

Posted by in category: space

This throws a curveball in my brain regarding UAPs.


A new study suggests Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean.
