Feasibility study suggests use of high-power lasers to contact alien civilizations

Published

on

We currently have, or could quickly develop, the technology to communicate with nearby alien worlds, according to a study recently published by the Astrophysical Journal. To accomplish such a feat, the study proposes using a 2-megawatt laser, pointed through a 30-meter telescope, to build a beacon with significant enough reach to be detected by civilizations up to thousands of light years away. With over 3,800 exoplanets already confirmed and around 3,000 others awaiting confirmation, communicating with those thought to be habitable is one of the next questions to consider.

If intelligent life were to exist on one of the planets surrounding our nearest stars, messages could potentially be sent between worlds using such a laser beacon in patterns similar to Morse code. A few years between messages might seem stark compared to the rate of exchange we’ve become used to amongst ourselves, and the wait for a first response might be daunting. However, the definitive revelation of not being alone in the universe might be worth the time invested.

In the study conducted at the Massachusettes Institute of Technology, author James R. Clark suggested that the beacon’s initial role would be to attract the attention of alien astronomers similar to how our attention is gained in identifying exoplanets. We study anomalies in the electromagnetic spectrums of other stars to find planets, and thus, our star’s spectrum would potentially seem unusual with a projecting laser beam, meriting more attention.

Clark noted that it would take a minimum of 2MW of energy to stand out against our sun’s infrared signal in a “cursory survey by an extraterrestrial intelligence”, which is how the size and wattage of the beacon were calculated. The feasibility of creating this communication tool was explored as part of a graduate school class Clark was enrolled in, and the study’s co-author is his professor, Kerri Cahoy.

Are there potentially habitable planets close enough to even justify utilizing such a technology? Perhaps. One of the better candidates could be the TRAPPIST-1 planetary system in the constellation Aquarius, where a star boasts at least 7 planets in orbit with rocky surfaces and sizes similar to Earth and Venus. Three have been determined to be potentially habitable.

The 40-light-year distance of the TRAPPIST-1 system from Earth would have a significant communications delay, however. At only 4 light years away, though, the exoplanet Proxima Centauri b, a slightly larger than Earth planet orbiting red dwarf star Proxima Centauri, could be a more promising candidate for finding alien pen pals.

Recent studies have pointed to hopeful prospects for its habitability, thus making a communication tool like the beacon in this study even more relevant. Further discussion would be needed, of course – do we want to reach out to other worlds? But the combination of a potentially habitable planet and the ability to communicate with it is an exciting consideration.

Wedbush analyst Dan Ives is doubling down on Tesla’s (NASDAQ:TSLA) long-term upside. In a post on X, the analyst stated that the electric vehicle maker could hit a $3 trillion market cap by the end of 2026 in a bullish scenario, thanks to the company’s efforts to develop and push its artificial intelligence programs. 

An aggressive valuation upside

Ives, Wedbush’s global head of tech research, stated in his post that Tesla is entering a pivotal period as its autonomy and robotics ambitions move closer to commercialization. He expects Tesla’s market cap to reach $2 trillion in 2026, representing roughly 33% upside from current levels, with a bull case up to a $3 trillion market cap by year-end.

Overall, Ives noted that 2026 could become a “monster year” for TSLA. “Heading into 2026, this marks a monster year ahead for Tesla/Musk as the autonomous and robotics chapter begins.  We believe Tesla hits a $2 trillion market cap in 2026 and in a bull case scenario $3 trillion by end of 2026… as the AI chapter takes hold at TSLA,” the analyst wrote

Ives also reiterated his “Outperform” rating on TSLA stock, as well as his $600 per share price target.

Unsupervised Full-Self Driving tests

Fueling optimism is Tesla’s recent autonomous vehicle testing in Austin, Texas. Over the weekend, at least two Tesla Model Ys were spotted driving on public roads without a safety monitor or any other occupants. CEO Elon Musk later confirmed the footage of one of the vehicles on X, writing in a post that “testing is underway with no occupant in the car.”

It remains unclear whether the vehicle was supported by chase cars or remote monitoring, and Tesla has not disclosed how many vehicles are involved. That being said, Elon Musk stated a week ago that Tesla would be removing its Safety Monitors from its vehicles “within the next three weeks.” Based on the driverless vehicles’ sightings so far, it appears that Musk’s estimate may be right on the mark, at least for now.

Production-ready Tesla Cybercab hits showroom floor in San Jose

Tesla has implemented subtle but significant updates to both the Cybercab’s exterior and interior elements.

Published

on

Tesla has showcased what appears to be a near-production-ready Cybercab at its Santana Row showroom in San Jose, California, giving visitors the closest look yet at the autonomous two-seater’s refined design. 

Based on photos of the near-production-ready vehicle, the electric vehicle maker has implemented subtle but significant updates to both the Cybercab’s exterior and interior elements, making the vehicle look more polished and seemingly more comfortable than its prototypes from last year.

Exterior and interior refinements

The updated Cybercab, whose photos were initially shared by Tesla advocate Nic Cruz Patane, now features a new frameless window design, an extended bottom splitter on the front bumper, and a slightly updated rear hatch. It also includes a production-spec front lightbar with integrated headlights, new wheel covers, and a license plate bracket. 

Notably, the vehicle now has two windshield wipers instead of the prototype’s single unit, along with powered door struts, seemingly for smoother opening of its butterfly doors. Inside, the Cybercab now sports what appears to be a redesigned dash and door panels, updated carpet material, and slightly refined seat cushions with new center cupholders. Its legroom seems to have gotten slightly larger as well. 

Cybercab sightings

Sightings of the updated Cybercab have been abundant in recent months. At the end of October, the Tesla AI team teased some of the autonomous two-seater’s updates after it showed a photo of the vehicle being driven through an In-N-Out drive-through by employees in Halloween costumes. The photos of the Cybercab were fun, but they were significant, with longtime Tesla watchers noting that the company has a tradition of driving its prototypes through the fast food chain’s drive-throughs.

Even at the time, Tesla enthusiasts noticed that the Cybercab had received some design changes, such as segmented DRLs and headlamps, actual turn signals, and a splitter that’s a lot sharper. Larger door openings, which now seem to have been teasing the vehicle’s updated cabin, were also observed at the time.

Tesla analyst realizes one big thing about the stock: deliveries are losing importance

Tesla analyst Dan Levy of Barclays realized one big thing about the stock moving into 2026: vehicle deliveries are losing importance.

As a new era of Tesla seems to be on the horizon, the concern about vehicle deliveries and annual growth seems to be fading, at least according to many investors.

Even CEO Elon Musk has implied at times that the automotive side, as a whole, will only make up a small percentage of Tesla’s total valuation, as Optimus and AI begin to shine with importance.

He said in April:

“The future of the company is fundamentally based on large-scale autonomous cars and large-scale and large volume, vast numbers of autonomous humanoid robots.”

Levy wrote in a note to investors that Tesla’s Q4 delivery figures “likely won’t matter for the stock.” Barclays said in the note that it expects deliveries to be “soft” for the quarter.

In years past, Tesla analysts, investors, and fans were focused on automotive growth.

Cars were truly the biggest thing the stock had to offer: Tesla was a growing automotive company with a lot of prowess in AI and software, but deliveries held the most impact, along with vehicle pricing. These types of things had huge impacts on the stock years ago.

In fact, several large swings occurred because of Tesla either beating or missing delivery estimates:

  • January 3, 2022: +13.53%, record deliveries at the time
  • January 3, 2023: -12.24%, missed deliveries
  • July 2, 2024: +10.20%, beat delivery expectations
  • October 3, 2022: -8.61%, sharp miss due to Shanghai factory shutdown
  • July 2, 2020: +7.95%, topped low COVID-era expectations with sizeable beat on deliveries

It has become more apparent over the past few quarters that delivery estimates have significantly less focus from investors, who are instead looking for progress in AI, Optimus, Cybercab, and other projects.

These things are the future of the company, and although Tesla will always sell cars, the stock is more impacted by the software the vehicle is running, and not necessarily the vehicle itself.
