This Is What Might Happen if an Asteroid Crashed Into Your Town

An online simulator lets you launch an asteroid at a locale of your choosing and ponder the potential outcome.

If an asteroid made of pure gold, with a diameter of 2,600 feet and blasting at 77,000 miles per hour, came in at an angle of 48 degrees and hit New York City’s Upper East Side, aka around where I live, I unfortunately now know what would happen.

Myself and 6,363,353 people would be vaporized within the space rock’s resulting crater, a massive chasm over half a mile deep. The shard would release more energy than the last volcanic eruption of Yellowstone, a colossal disaster that, thousands of years ago, spewed ash, magma and debris far enough to cover most of the continental United States.

Or at least that’s what I learned from an asteroid simulation website this afternoon while sipping on a cup of coffee.

The Asteroid Launcher is a free, data-driven concept created by Neal Agarwal, a developer widely known by his online persona: neal.fun. Agarwal’s goal is basically to blend immense arrays of data and interesting mental dilemmas to form clever, interactive online thought experiments, like this one that tells you what kind of devastation would follow an asteroid smashing into your town.

«The main inspiration,» Agarwal told me over email, «was definitely growing up watching movies like Deep Impact and Armageddon! I’ve always wanted to have an online tool that would let me test out different impact scenarios and see the effects.»

But of course, the key here with Asteroid Launcher lies in Agarwal’s pseudonym.

There are thankfully no known significant impact threats for the next hundred years or more, according to NASA — and, worst case, the agency is well on its way toward generating a sort of asteroid defense system with the resounding success of its DART mission, which took place earlier this year.

Still, it doesn’t hurt to cater to our intrusive thoughts once in a while. Just for fun.

Peruse Agarwal’s projects and you’ll find an awesome array of rabbit holes to get lost in.

The Size of Space progressively presents you with larger and larger objects, starting with an astronaut and making its way through stars so enormous they make our sun look like a feeble yellow pom-pom. Spend Bill Gates’ Money offers you $100 billion to spend on items ranging from a 12 pack of Coca-Cola all the way to a literal Boeing 747 commercial airplane. It shows you how much money multibillionaires are working with day to day.

And my personal favorite, Absurd Trolley Problems takes you on an illustrative, ethical journey based on English philosopher Philippa Foot’s fictional scenario where an onlooker has the choice to save five people in danger of being hit by a trolley — except the only way to save them is by killing one person in their stead. The hard part about this isn’t so much the decisions, but the fact that you should, hypothetically, remain consistent in every one of those decisions.

«I’ve kept a big ideas list since I was 16, and have recently passed 1,000 project ideas written down (most of them terrible),» Agarwal said. «The ideas can come from everywhere, from books and movies to a conversation with a friend. I think the important thing is writing them down and being as open as possible to new and weird ideas. Sometimes two to three bad ideas can combine and form a great project.»

Which brings us to Agarwal’s latest endeavor: Asteroid Launcher.

You begin by designing your own asteroid, entering a material, rock diameter, speed and impact angle. Then, you can select any location on a realistic map to the left of the screen. All that remains, at that point, is to click a giant button that says LAUNCH ASTEROID.

Boom.

You arrive at a page that tells you, theoretically, what you’ve just done to your location of choice.

These results are surprisingly detailed, as Agarwal embedded his code with asteroid information gleaned from academic science publications, such as a doctoral thesis about asteroid impact risk and a peer-reviewed population vulnerability model authored by experts from NASA, Lancaster University and the University of Southampton.

However, it does appear that some question the results of Asteroid Launcher — one scientist, for instance, tweeted his preference for the more old-school Earth Impact Effects Program to satisfy doomsday cravings.

Though, to that end, Agarwal says the Earth Impact Effects Program uses the same equations as Asteroid Launcher because both are based on a research paper written by Gareth Collins, an asteroid impact expert at Imperial College London. «They’ll give pretty much the same results,» he explained, noting that Clemens Rumpf, an asteroid risk expert who formerly worked at NASA, also contributed to his project.

«The goal of neal.fun is to bring back the weird and fun internet!» Agarwal said. «I grew up at a time when the internet was full of strange and fun flash games and experiments, and watched that all slowly go away as social media took over. Now the web is finally becoming powerful enough again to create fun digital experiences, and I’m excited to keep exploring the potential with new projects.»

On Asteroid Launcher, once you’ve pressed the big red button, scroll down a little, and you’ll catch far more than fatalities spurred by your asteroid design.

Agarwal tells you how many gigatons of TNT your explosion equaled, how many people would receive second-degree burns if your asteroid was closer to a huge fireball, the radius within which peoples’ eardrums would rupture from the shock wave and within which homes would be completely leveled from wind speeds upon impact.

It’s darkly obsessive to check out as many asteroid designs as you can. Immediately after making my dream gold impactor, I plugged in the stats of the asteroid that NASA’s DART spacecraft punched into in an attempt to change the relatively small space rock’s orbit around a larger hunk of space rock.

I couldn’t get things to be completely accurate, because this is so theoretical, but here’s what I came up with.

Dimorphos is considered to be made of «rubble,» aka a bunch of materials, so for material, I went with generic stone. It’s actually about 525 feet in diameter, but Asteroid Launcher requires some rounding. I put in 500 feet. As for speed at time of impact, a parameter we don’t know, I popped in the speed at which the DART spacecraft hit the rock, because, well, why not? That came out to something like 14,400 miles per hour, which had to be rounded as well. I set the location to London and angle to 90 degrees for no reason whatsoever.

Here’s what we got for results — they’re much less shocking than my first ridiculous, gleaming monster asteroid.

My next plan was to input the parameters of the dinosaur-killer asteroid, Chicxulub. But get this: It was so gigantic it didn’t even fit in the diameter section.

«Asteroid impact science is still an evolving field and not everything is known yet,» Agarwal said. «Generally the larger the asteroid, the more uncertain we are about the effects.»

OpenAI Launches ChatGPT Health: A Dedicated Tab for Medical Inquiries

The company wants you to upload your medical records and connect the wellness apps you use.

ChatGPT is expanding its presence in the health care realm. OpenAI said Wednesday that its popular AI chatbot will begin rolling out ChatGPT Health, a new tab dedicated to addressing all your medical inquiries. The goal of this new tab is to centralize all your medical records and provide a private area for your wellness issues.

Looking for answers about a plethora of health issues is a top use for the chatbot. According to OpenAI, «hundreds of millions of people» sign in to ChatGPT every week to ask a variety of health and wellness questions. Additionally, ChatGPT Health (currently in beta testing) will encourage you to connect any wellness apps you also use, such as Apple Health and MyFitnessPal, resulting in a more connected experience with more information about you to draw from.

Online privacy, especially in the age of AI, is a significant concern, and this announcement raises a range of questions regarding how your personal health data will be used and the safeguards that will be implemented to keep sensitive information secure — especially with the proliferation of data breaches and data brokers.

«The US doesn’t have a general-purpose privacy law, and HIPAA only protects data held by certain people like health care providers and insurance companies,» Andrew Crawford, senior counsel for privacy and data at the Center for Democracy and Technology, said in an emailed statement.

He continued: «The recent announcement by OpenAI introducing ChatGPT Health means that a number of companies not bound by HIPAA’s privacy protections will be collecting, sharing and using people’s health data. And since it’s up to each company to set the rules for how health data is collected, used, shared and stored, inadequate data protections and policies can put sensitive health information in real danger.»

OpenAI says the new tab will have a separate chat history and a memory feature that can keep your health chat history separate from the rest of your ChatGPT usage.

Further protections, such as encryption and multifactor authentication, will defend your data and keep it secure, the company says. Health conversations won’t be used to train the chatbot, according to the company.

Privacy issues aside, another concern is how people intend to use ChatGPT Health. OpenAI’s blog post states the service «is not intended for diagnosis or treatment.»

The slope is slippery here. In August 2025, a man was hospitalized after allegedly being advised by the AI chatbot to replace salt in his diet with sodium bromide. There are other examples of AI providing incorrect and potentially harmful advice to individuals, leading to hospitalization.

OpenAI’s announcement also doesn’t touch on mental health concerns, but a blog post from October 2025 says the company is working to strengthen its responses in sensitive conversations. Whether these mental health guardrails will be enough to keep people safe remains to be seen.

OpenAI didn’t immediately respond to a request for comment.

If you’re interested in ChatGPT Health, you can join a waitlist, as the tab isn’t yet live.

(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

I Tested the Honor Magic 8 Pro and Found a Huge Problem With the Camera

I discovered a catastrophic problem with this phone’s cameras and it needs to be fixed fast.

I’ve found a big problem with the Honor Magic 8 Pro’s camera that urgently needs addressing. I’ve taken hundreds of test photos in my weeks with the company’s latest flagship phone, and while plenty of them are perfectly decent, many of the images I’ve taken with the ultrawide lens display horrendous image processing issues around the edges that ruin them completely.

I discovered the issue when I first got the phone late last year, and while it’s had several significant software updates since then, the problems persist. So what’s gone wrong? It’s possible that I’m monumentally unlucky and happen to have been given a broken unit. If so, I fully expect the replacement models I’ll be testing to be free of any issues. Or, maybe it’s a more widespread problem and I’ll see the same issues cropping up again. I personally think it’s more likely to be an issue at the software level, and as such, it could be a simple fix for Honor to push out in the coming days and weeks.

I’ve spoken to Honor about this and, unsurprisingly, the company is keen to say that this isn’t widespread, stating «Our internal investigation confirmed that the issue was limited to an isolated hardware anomaly in that specific early development sample. It doesn’t reflect the hardware or software polish of the final retail units now launching in the European market.» And sure, my test unit was an early non-EU version, but it is also the phone that the company did send me to review. Receiving early prerelease samples is common in the industry and while small hiccups can sometimes be expected, I rarely find such significant problems as this.

Honor is sending additional retail units for further testing and I hope that I’m able to confirm that this isn’t an issue seen on all models. I was prepared to write a full review of this new flagship phone, but these camera issues are severe and raise more questions than answers. I will update this article with more information and my testing results as they become available.

Even if it is an isolated incident, it’s still disappointing to see such significant problems on a new phone, especially a flagship that costs £1,099 in the UK. Honor doesn’t officially sell its phones in the US, but for reference, that price converts to roughly $1,480.

The phone does have some positives. I like its processor performance and display, for example, which I’ll come on to later. But the camera issues I’ve seen mean I can’t recommend buying this phone until it’s clear whether they’re limited to my review device or if they’re issues common across all models.

Let’s take a closer look at what’s going on.

Honor Magic 8 Pro camera troubles

Taken with the camera’s standard zoom, the shot above is fine — there’s a decent amount of detail and the exposure is even overall.

But switch to the ultrawide mode and things go horribly wrong. There’s a vibrant purple fringe around the edge that’s full of image processing artifacts that ruin the shot.

It’s not a subtle problem; it’s a huge red flag that something is very wrong with this phone.

For reference, here’s the iPhone 16 Pro’s ultrawide shot. Notice the difference?

As you can see, it’s not an isolated incident. It seems to be more apparent when there are areas of shadow in the edges. It makes me suspect that the phone is seeing these dark patches and trying — and failing — to brighten them and add detail back into the scene. It’s not dissimilar to the early problems I found on Google’s Pixel 8 Pro, which also struggled with shadow detail, suggesting to me that this is a software fault, rather than a mechanical problem with my unit.

It also doesn’t seem to affect the ultrawide lens when recording video, which again suggests it’s not a hardware issue as I’d expect to see the same problems from the lens in any mode. The downside of that is that it could theoretically affect all models of the Honor Magic 8 Pro. However, the big upside is that software problems can be easily remedied with over-the-air updates.

To be honest, I don’t love the camera elsewhere, either. The image processing has gone overboard in this image, brightening the shadows and trying to rescue the highlights in the background excessively. It’s resulted in an over-processed image that looks unnatural.

The iPhone 16 Pro’s attempt has allowed those shadows to remain what they are — shadows — and I vastly prefer this version as a result.

I’ve also noticed that there can be significant color shifts when switching between the main and ultrawide lenses, which I would again prefer not to see on a camera phone of this price.

However, this could be attributed to the same software processing issues I’ve already discussed, so I’ll have to leave my verdict on the camera for when I’ve done more testing.

On the upside, this shot of the Tennents brewery in Glasgow looks good.

And I like the colors and tones in this sunset scene in Edinburgh. So it’s not all bad — it can take a decent photo sometimes. So what about the rest of the phone?

Honor Magic 8 Pro: Display, performance and battery life

I like the phone’s 6.71-inch display, which is bright and vibrant. It’s lovely for gaming, too, thanks to its max 120Hz refresh rate. It’s powered by Qualcomm’s latest Snapdragon Elite Gen 5 processor, which puts in some of the best scores we’ve ever seen on our benchmark tests for both processor performance and graphics processing.

It certainly feels nippy in everyday use. Games like Genshin Impact, unsurprisingly, played smoothly at max graphics settings. The phone runs on a 6,270-mAh battery, which, while sizable, only gave average results on our battery drain tests. Battery performance sits alongside phones like the Galaxy S25 or Google Pixel 10, but it’s a big step below the iPhone 17 Pro Max or OnePlus 15.

If it feels like I’m glossing over the rest of the phone somewhat, it’s because I am. With the issues I’ve seen so far, it’s possible that there may be other early teething troubles elsewhere, so I’m going to hold off giving any kind of definitive verdict on any part of the phone until I’ve tested more models and have a full appreciation of what the phone is really like to use.

Honor Magic 8 Pro: Should you buy it?

Right now, I absolutely don’t think you should. The issues I’ve seen with the camera are significant and badly need addressing. It could be that it’s a simple software fix that can be rolled out in the coming weeks, or it might be an isolated incident that affects me and me alone. I’ll be retesting on multiple devices and it could be that they’re absolutely fine.

But unless you’re desperate for a new phone today and you absolutely have to have an Honor phone, then I recommend waiting until we’ve got more clarity about how deep these problems lie.
