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.

Tesla gets its latest short from Michael Burry: ‘Happy it jumped back to this level’

Published

Tesla short seller Michael Burry, the subject of the film “The Big Short,” where he was portrayed by Steve Carell, has revealed he has opened a new bet against the stock.

In a new update to his Substack newsletter in a post titled “Trading Post June 30, 2026,” Burry revealed a new set of bets against Tesla, Caterpillar, NVIDIA, Applied Materials Inc., and the iShares Semiconductor ETF.

In regard to Tesla, Burry wrote:

“And finally I shorted Tesla at 416.22. Happy it jumped back to this level.”

This means Burry likely opened his new short position after the company’s recent rally on Wall Street, which saw Tesla shares sink in mid-May, only to recover to well over the $400 mark. Currently, shares trade at around $427.

The company saw a big Tuesday as shares climbed considerably, over 10 percent. The size of the Tesla short was not provided, nor did Burry give any information on the position’s structure, the number of shares, dollar value, or whether options were used in the short.

The Tesla and SpaceX merger everyone is talking about is quietly building

Over the years, Burry has been one of the more vocal critics of Tesla, calling its share price “media inflated,” and saying it was “ridiculously overvalued” as recently as December.

The company has largely transitioned away from being known as an automotive company and instead is much more widely regarded as an AI play, mostly due to its Full Self-Driving efforts, Optimus robot development, and data collection related to both.

This has not pulled those skeptics away from being vocal about their distaste for how Tesla is valued, but there’s no denying that the company is a global force in many things, including sustainable energy, automotive, and AI.

SpaceX gets initial stock coverage from Tesla’s biggest bull

Wedbush Securities is initiating stock coverage on SpaceX (NASDAQ: SPCX), marking the first comments on the company since it went public several weeks ago. Wedbush and its analyst handling coverage, Dan Ives, are widely bullish on fellow Musk company Tesla (NASDAQ: TSLA).

Ives wrote his first note initiating coverage of SpaceX shares on Wednesday with a $190 price target and an ‘Outperform’ rating. The firm believes the company is well positioned off of its IPO because of its wide array of projects, including AI compute power and infrastructure, connectivity projects, and launches.

“We view SpaceX as one of the most differentiated assets within the tech market with a strong footprint across its three core markets, with Starlink driving success with connectivity,” Ives wrote, “Starship launches leading to a demand flywheel and increasing deal flow for its Colossus clusters.”

Wedbush leans heavily on Starlink, which they say is the “profitability driver given the strength of its recurring revenue base of ~12 million subscribers as of June 5th.” Ives believes Starlink is still in the “early innings” of penetrating the global telecommunications and broadband market, as it only holds less than a 1 percent share. However, this number is sure to increase over time.

It also highlights the importance of Starship, which it says is an “essential layer” of SpaceX’s overall success. SpaceX developing and displaying the ability to reuse rockets is a major cost and reliability advantage “as it reduces the necessary hardware launch costs while generating a feedback loop for future flights to improve their launch flight rate without accelerating capex spend.”

Finally, SpaceX’s recent AI/Compute projects are also very elementary, Ives writes. It is worth mentioning Wedbush said its $190 price target is derived from a valuation forecast that sees the company yielding roughly $2.48 trillion of implied enterprise value.

There are also some factors that Wedbush did not take into account with its initial coverage. The firm wrote in the note:

“We note that there is optional value coming from Starship’s accelerating scale towards sub-$200/kg unit economics, orbital data centers, and enterprise AI monetization as these factors could drive meaningful upside but these face major hurdles, so we do not take that into account with our valuation.”

SpaceX shares are down just over 2 percent today, trading at around $167 at the time of publication.

Tesla expands massive safety feature worldwide in latest update

Tesla has expanded the footprint of a massive safety feature worldwide with a recent Software Update labeled as 2026.20.6. The expansion of the “Blind Spot Warning While Parked” feature represents the more widespread availability of the feature, which aims to prevent “dooring.”

Dooring is when a driver or passenger opens a car door into the path of an oncoming road user, usually a cyclist or motorcyclist. It is among the most common types of cycling accidents, the League of American Bicyclists says.

For this reason, Tesla created a feature that warns occupants not to open the door because an object is approaching. The feature will sound a chime, and it will also delay the opening of the door to prevent an incident.

The release notes state (via Not a Tesla App):

“If you attempt to open a door while an approaching object is detected in your blind spot (for example, a bicyclist approaching from behind) a chime sounds, and your door will not open upon initial button press. Wait a short time and press the button a second time to override the warning.”

Tesla initially rolled out this feature back in 2024 with the Model 3 “Highland.” However, it remained with the Model 3 exclusively for over a year; that was until Tesla added it to the Cybertruck this past Spring.

Now, it is making its way to the new Model Y, 2021 and newer Model S, and 2021 or newer Model X.

The prevention of dooring incidents could eliminate many injuries to cyclists, especially in an urban setting. Dooring accounts for 10-20 percent of bike-related crashes in major cities, and over 17,000 dooring-related incidents were treated in the U.S. over the course of a decade. These usually involve fractures, contusions, and head trauma.
