Plunge Across a Black Hole’s Event Horizon Courtesy of New NASA Video
The clip was made over five days using NASA’s Discover supercomputer.
Black holes, those mysterious places in space where gravity is so strong that not even light can escape, make for great movie plot twists. But Hollywood aside, there are many things humans don’t understand about a black hole. A new video from NASA attempts to show what it looks like when an object crosses the event horizon, or boundary, of a black hole. Since no technology can survive this experience, this might be as close as we’re ever going to get.
The video, created by NASA’s Jeremy Schnittman and Brian Powell, begins with a camera view floating toward a black hole. As the camera approaches, it orbits around the black hole before the camera flies into the burning gas that surrounds it. It delivers a great view of some photon rings before entering the event horizon. From there, the camera experiences the stretching and distortion that’s colorfully known as spaghettification, as it’s pulled into the black hole. As the camera is sucked in, the simulated sky shrinks. Moments later, the camera goes dark as it hits the singularity, the one-dimensional center of a black hole, where the laws of physics cease to exist.
The simulation then plays again, but with explanations overlaid to explain each step of the process. The video then replays a third time, now in slow motion, and zoomed in to show the intricacies of the photon ring layers. It ends with a final replay of the whole simulation but this time with more technical details about how it was created. In all, the simulation is much more detailed than the images we have of the Milky Way’s black hole.
It’s quite the trip, and produces some truly striking images, especially those of the photon ring layers and the sky rapidly shrinking as the camera is pulled in.
Schnittman also made a second video with a simulation of the camera making a couple of orbits around the black hole before safely escaping. That one is a 360-degree YouTube video, allowing viewers to look around and see the entire trip from multiple angles.
The simulated black hole is enormous
The black hole in the simulation measures about 16 million miles (25 million kilometers) in diameter. That’s way bigger than Earth, and comparable to some black holes in our own cosmic backyard.
In case you, too, want to go flying into a black hole, Schnittman has some advice.
«If you have the choice, you want to fall into a supermassive black hole,» he said. «Stellar-mass black holes, which contain up to about 30 solar masses, possess much smaller event horizons and stronger tidal forces, which can rip apart approaching objects before they get to the horizon.»
In short, if you opted for a small black hole in this hypothetical situation, you might be torn to bits before you got to the good stuff. Supermassive black holes seem to be the way to go.
Thanks, NASA’s Discover supercomputer
The simulation was created using NASA’s Discover supercomputer, which is located at the NASA Center for Climate Simulation in Greenbelt, Maryland. The project generated approximately 10 terabytes of data, which NASA says is equivalent to roughly half the estimated text content in the Library of Congress.
It took about five days to complete and used just 0.3% of Discover’s 129,000 processors. NASA says the same work would’ve taken about a decade on a regular laptop.
Why work on such a huge and comprehensive simulation of a black hole? Schnittman says it’s mostly for research.
«People often ask about this, and simulating these difficult-to-imagine processes helps me connect the mathematics of relativity to actual consequences in the real universe,» Schnittman said in a post on NASA’s site. «So I simulated two different scenarios, one where a camera — a stand-in for a daring astronaut — just misses the event horizon and slingshots back out, and one where it crosses the boundary, sealing its fate.»

OnePlus and Oppo to Raise Smartphone Prices as Memory Costs Climb
Oppo says rising costs for key phone components will trigger price adjustments on some devices starting March 16.
Chinese smartphone-makers OnePlus and Oppo plan to raise prices on some existing models starting next week, according to a 9to5Google report citing GizmoChina and a notice posted on Oppo’s China online store.
In its notice, Oppo said it would adjust pricing after evaluating rising costs for several key components used in its mobile phones. The changes are expected to take effect around March 16 and will affect some of the company’s more affordable smartphones, as well as some OnePlus models.
Flagship devices — like those in the Find and Reno series — are not expected to be affected for now. The reported adjustments currently appear to be limited to China.
The move highlights growing pressure across the smartphone supply chain as component costs climb. Analysts say prices for memory and storage chips used in phones have been rising in recent months as demand surges across the tech industry.
Much of the chip demand is coming from the rapid buildout of AI data centers, which rely on large amounts of high-performance memory.
That pressure isn’t limited to Oppo and OnePlus. Analysts say smartphone brands across the industry are facing rising component costs amid increased demand for memory chips.
As manufacturers shift production toward higher-margin memory used in AI servers, supply for consumer electronics such as smartphones and laptops can tighten.
If component costs continue to rise, manufacturers may face difficult choices later this year, including raising retail prices or adjusting device specifications to offset higher manufacturing costs.
OnePlus and Oppo didn’t immediately respond to a request for comment.

Harvard Business Review Study Finds ‘AI Brain Fry’ Is Leaving Workers Mentally Fatigued
Study participants reported increased mental fatigue while using AI tools, but less burnout overall.
Workers who excessively use AI agents and tools at work are at increased risk of mental fatigue, according to a recent Harvard Business Review study. In certain industries, more than 25% of hired professionals report increased mental strain due to their role in AI oversight — though these professionals also generally experienced less burnout than peers who aren’t using AI.
This phenomenon — which the researchers refer to as «AI brain fry» — is described as a «‘buzzing’ feeling or a mental fog» that caused study participants to develop headaches and difficulty focusing and making decisions. Individuals pointed to being overwhelmed by large amounts of information and to frequent task switching as the reasons for these feelings.
Studied individuals experienced more brain fry when they utilized AI agents to manage a workload beyond their own cognitive capacity. When participants used AI to replace mundane, repetitive tasks, managing the growing number of tools led to increased mental fatigue.
Crucially, the study found that fewer individuals who used these AI agents reported workplace burnout.
The researchers predict that this is because burnout testing assesses emotional and physical distress. In contrast, they report, acute mental fatigue «is caused by marshalling attention, working memory and executive control beyond the limited capacity of these systems.»
These are the processes that are taxed when study participants use multiple AI tools in their workflow, according to the researchers.
The Harvard study identifies several business costs incurred by workers suffering from AI brain fry. The foremost consequence is that these individuals may end up making lower-quality decisions. «Workers in [the] study who endorsed AI brain fry experience 33% more decision fatigue than those who did not,» the study reports. Workers who report AI brain fry were also more likely to self-report making both minor and major errors at their jobs.
Another recent Harvard Business Review study similarly found that employees who use AI tools «worked at a faster pace, took on a broader scope of tasks and extended work into more hours of the day,» but warned that «workload creep can in turn lead to cognitive fatigue, burnout and weakened decision-making.»
