The Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole. Since then, it has been boosting the resolution and filling in the details of an environment dominated by the most extreme gravity in the Universe.

But which gravity are we talking about? Because of its incompatibility with quantum mechanics and our current inability to explain dark matter, people have proposed all sorts of variants of gravity that go beyond general relativity and clean up some of the physics’ awkwardness. It’s possible that the extreme environment near a black hole amplifies the differences among at least some of these hypotheses. So, a group of physicists decided to see whether any of those differences might be large enough that the next generation of telescopes might be able to rule out some potential replacements for relativity.

Searching for subtlety

Any replacement for general relativity faces an awkward challenge: General relativity does pretty well at explaining everything from the large-scale structure of the Universe to phenomena we can measure right here on Earth. So, any alternative theories would have to differ from relativity in very subtle ways that might be extremely difficult to detect.

One of the world’s most ruthless and advanced hacking groups, the Russian state-controlled Sandworm, launched a series of destructive cyberattacks in the country’s ongoing war against neighboring Ukraine, researchers reported Thursday.

In April, the group targeted a Ukrainian university with two wipers, a form of malware that aims to permanently destroy sensitive data and often the infrastructure storing it. One wiper, tracked under the name Sting, targeted fleets of Windows computers by scheduling a task named DavaniGulyashaSdeshka, a phrase derived from Russian slang that loosely translates to “eat some goulash,” researchers from ESET said. The other wiper is tracked as Zerlot.

A not-so-common target

Then, in June and September, Sandworm unleashed multiple wiper variants against a host of Ukrainian critical infrastructure targets, including organizations active in government, energy, and logistics. The targets have long been in the crosshairs of Russian hackers. There was, however, a fourth, less common target—organizations in Ukraine’s grain industry.

Tesla shareholders today voted to approve a compensation plan that would pay Elon Musk more than $1 trillion over the next decade if he hits all of the plan’s goals. Musk won over 75 percent of the vote, according to the announcement at today’s shareholder meeting.

The pay plan would give Musk 423,743,904 shares, awarded in 12 tranches of 35,311,992 shares each if Tesla achieves various operational goals and market value milestones. Goals include delivering 20 million vehicles, obtaining 10 million Full Self-Driving subscriptions, delivering 1 million “AI robots,” putting 1 million robotaxis in operation, and achieving a $400 billion adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization).

Musk has threatened to leave if he doesn’t get a larger share of Tesla. He told investors last month, “It’s not like I’m going to go spend the money. It’s just, if we build this robot army, do I have at least a strong influence over that robot army? Not control, but a strong influence. That’s what it comes down to in a nutshell. I don’t feel comfortable building that robot army if I don’t have at least a strong influence.”

AT&T has been told to stop running ads that falsely promise all customers a free iPhone. The rebuke came from the advertising industry’s official watchdog just a week after AT&T sued the organization over a different advertising dispute.

BBB National Programs’ National Advertising Review Board (NARB) “has recommended that AT&T Services, Inc. modify its advertising to avoid conveying a false message regarding eligibility for an iPhone device offer,” the group, which runs the ad industry’s self-regulatory system, said today.

Verizon initiated the case by challenging AT&T’s “Learn how everyone gets iPhone 16 Pro on us” claim. BBB National Programs’ National Advertising Division (NAD) ruled in favor of Verizon in September 2025. AT&T appealed but lost the challenge in the NARB decision announced today.
