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.»

These Small Tweaks Can Give Your Old Android a Big Speed Boost

Instead of buying a new phone, try clearing some space, updating your software and changing a few battery settings.

If your Android is a few years old and starting to feel sluggish, it doesn’t mean you have to rush out and buy the newest flagship model. Thanks to longer software support from brands like Google and Samsung, older models can still run smoothly, as long as you give them a little attention.

Before you start shopping for a replacement, try a few simple adjustments. You might be surprised by how much faster your phone feels once you clear out unused apps, optimize battery use and turn off background drains.

Whether you use a Samsung Galaxy, Motorola or OnePlus phone, chances are you can still improve battery life and overall speed without buying something new. Just remember that Android settings vary slightly from brand to brand, so the menus may look a little different depending on your phone.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

Settings to improve your battery life

Living with a phone that has poor battery life can be infuriating, but there are some steps you can take to maximize each charge right from the very beginning:

1. Turn off auto screen brightness or adaptive brightness and set the brightness level slider to under 50%

The brighter your screen, the more battery power it uses.

To get to the setting, pull down the shortcut menu from the top of the screen and adjust the slider, if it’s there. Some phones may have a toggle for auto brightness in the shortcut panel; otherwise, you need to open the settings app and search for «brightness» to find the setting and turn it off.

2. Use Adaptive Battery and Battery Optimization

These features focus on learning how you use your phone, including which apps you use and when, and then optimizing the apps and the amount of battery they use.

Some Android phones have a dedicated Battery section in the Settings app, while other phones (looking at you, Samsung) bury these settings. It’s a little different for each phone. I recommend opening your settings and searching for «battery» to find the right screen. Your phone may also have an adaptive charging setting that can monitor how quickly your phone battery charges overnight to preserve its health.

Why you should use dark mode more often

Another way to improve battery life while also helping save your eyes is to use Android’s dedicated dark mode. Any Android phone running Android 10 or newer will have a dedicated dark mode option.

According to Google, dark mode not only reduces the strain that smartphone displays cause on our eyes but also improves battery life because it takes less power to display dark backgrounds on OLED displays (used in most flagship phones) than a white background.

Depending on which version of Android your phone is running, and what company made your phone, you may have to dig around the settings app to find a dark mode. If your phone runs Android 10 or newer, you’ll be able to turn on system-wide dark mode. If it runs Android 9, don’t despair. Plenty of apps have their own dark mode option in the settings that you can use, whether or not you have Android 10.

To turn it on dark mode, open the Settings app and search for Dark Mode, Dark Theme or even Night Mode (as Samsung likes to call it). I suggest using dark mode all the time, but if you’re not sure, you can always set dark mode to automatically turn on based on a schedule, say from 7 p.m. to 7 a.m. every day, or allow it to automatically switch based on your location at sunset and sunrise.

Keep your home screen free of clutter

Planning to hit up the Google Play Store for a bunch of new Android apps? Be prepared for a lot of icon clutter on your home screen, which is where shortcuts land every time you install something.

If you don’t want that, there’s a simple way out of this: Long-press on an empty area of your home screen and tap Settings. Find the option labeled something along the lines of Add icon to Home Screen or Add new apps to Home Screen and turn it off.

Presto! No more icons on the home screen when you install new apps. You can still add shortcuts by dragging an app’s icon out of the app drawer, but they won’t appear on your home screen unless you want them to.

Set up Do Not Disturb so that you can better focus

If your phone routinely spends the night on your nightstand, you probably don’t want it beeping or buzzing every time there’s a call, message or Facebook alert — especially when you’re trying to sleep. Android offers a Do Not Disturb mode that will keep the phone more or less silent during designated hours. On some phones, this is referred to as the Downtime setting or even Quiet Time.

Head to Settings > Sounds (or Notifications), then look for Do Not Disturb or a similar name. If you can’t find it, search for it using the built-in search feature in your settings.

Using the feature, you can set up a range of hours when you want to turn off the digital noise. Don’t worry, any notifications you get while Do Not Disturb is turned on will still be waiting for you when you wake up. Also, you can typically make an exception that allows repeat callers and favorite contacts’ calls to go through. Turn that on. If someone is calling you in an emergency, odds are they are going to keep trying.

Always be prepared in case you lose your phone or it’s stolen

Is there anything worse than a lost or stolen phone? Only the knowledge that you could have tracked it down if you had turned on Google’s Find My Device feature.

To prepare for a successful recovery, here’s what you need to do: Open the Settings app and then search for Find My Device. It’s usually in the Security section of the Settings app.

If you have a Samsung device, you can use Samsung’s Find My Mobile service, which is found in Settings > Biometrics and security > Find My Mobile.

Once that’s enabled, you can head to android.com/find from any PC or mobile device and sign in to your account. Samsung users can visit findmymobile.samsung.com to find a lost phone.

If you have trouble setting any of this up, be sure to read our complete guide to finding a lost Android phone.

Assuming your phone is on and online, you should be able to see its location on a map. From there, you can make it ring, lock it, set a lock screen note to tell whoever has it how to get it back to you, or, worst-case scenario, remotely wipe the whole thing.

And always keep your phone up to date

As obvious as it may seem, a simple software update could fix bugs and other issues slowing down your Android device.

Before you download and install the latest software update, make sure your device is connected to Wi-Fi, or else this won’t work.

Now, open the Settings application and type in Update. You’ll then either see Software update or System update — choose either one. Then just download the software, wait for a few minutes and install it when it’s ready. Your Android device will reboot and install the latest software update available.

There’s a lot more to learn about a new phone. Here are the best ways to boost your cell signal, and here’s a flagship phone head-to-head comparison. Plus, check out CNET’s list of the best cases for your Samsung phone. More of an Apple fan? We have tips for boosting your iPhone’s performance, too.

I’m Finally Using the iPhone 17 Pro’s Camera Control, Thanks to These iOS 26 Settings

In just a month, I’ve already used Camera Control on my iPhone 17 Pro Max more than I did in a whole year with the iPhone 16 Pro.

I was keen on using the Camera Control button when it first debuted on the iPhone 16 Pro. But in over a year of use, it caused more accidental swipes and presses than its intended use cases to take photos and adjust camera settings. I was frustrated with the experience and hoped that Apple would remove it from the iPhone 17 lineup. Instead, the Cupertino, California-based company made its touch-sensitive capacitive control surface more customizable with iOS 26. And I’m happy to report that it helped!

I’ve been using the iPhone 17 Pro since launch and spent 5 to 10 minutes customizing the Camera Control to my liking. The result? Minimized accidental swipes and more conscious usability.

I transformed my Camera Control experience by changing a few iOS 26 settings

When setting up a new iOS 26-supported iPhone, Apple includes a toggle (now turned off by default) called Light press to adjust Zoom, Exposure and more. This is what used to cause a lot of fake input earlier. I’m glad it is turned off by default.

Apple now also lets you customize the Camera Control further from the Settings menu. I tweaked settings there to personalize my shortcuts, functionalities and more.

For example, I’ve set the Camera Control to launch a Code Scanner on Double Click without requiring the screen to be on. This allows me to scan and pay at payment kiosks (my most frequently used mode of payment) without needing to open the payment app and then tap on a menu to scan a code. If I enter the Code Scanner without Face ID, it requires authentication before making the payment, so it is still as secure as ever.

Earlier, I had set an Action Button shortcut to open Google Pay, but I realized I still need a one-press solution to turn the phone to silent mode. Adding a Code Scanner shortcut to Camera Control frees the Action Button to be my Silent Switch again. Moreover, Code Scanner lets you select from multiple apps to pay a vendor, which could be useful for people who use multiple payment apps.

Secondly, I have turned off the Swipe gesture and selected only three controls that I use most often. Now, when I open the Camera app, I can lightly press on the Camera Control button and then swipe between my selected controls. It doesn’t register swipes from the get-go. This has reduced fake touches and my frustrating experience with the swipe gesture.

To further streamline my controls, I chose Exposure, Styles and Tone, and left out Depth, Zoom and Cameras. This way, I have access to hidden viewfinder settings with a single press-and-swipe gesture at my fingertips.

I also turned off the Clean Preview toggle, so I can still switch between cameras with a single tap, and switched on the Lock Focus and Exposure toggle for a light press-and-hold gesture.

Customizing these settings helped me personalize Camera Control and use it more often. Now, it appeals to me with the settings I need and the way I need them, instead of being an overcrowded mess. And you can personalize your Camera Control, too. Here’s how:

Change Camera Control launch functionality

You can use Camera Control as another Action Button to launch an app of your choice. The only requirement is that the app should have access to the camera.

Go to Settings > Camera > Camera Control.
Under Launch Camera, select the app you need.
Go back and select Single Click or Double Click to open the said app.

I rely on Double Click so I don’t accidentally trigger an app when taking out the iPhone from my pocket. In my opinion, it is the safer and more convenient choice.

Under the same Launch Camera menu, you can also choose if you want the screen to be on or off when opening the app. I have turned it off to save the extra step of scanning my face to access the said app.

Choose the Controls that you want to appear on Camera Control

Apple allows you to choose from six controls, namely, Exposure, Depth, Zoom, Cameras, Styles and Tone. I have chosen three because the other three are available as on-screen toggles in the viewfinder.

Go to Settings > Camera > Camera Control.
Under Controls, make sure Camera Adjustments is turned on.
Tap on Customize.
Under Gesture, turn on Light Press and toggle off Swipe.
Under Controls, choose the functionalities you need.
Now, turn off the Clean Preview toggle if you require the viewfinder toggles to remain accessible.

You can further adjust the Camera Control pressure by going into Settings> Camera > Camera Control > Accessibility.

Turn on Lock Exposure and Focus with Camera Control

This setting will help you lock the exposure and focus without needing to press and hold on the viewfinder. It can be beneficial when you need consistent settings, especially when moving the camera from one subject to another.

Go to Settings > Camera > Camera Control.
Swipe down to Lock Exposure and Focus.
Tap on the toggle to turn it on.

For me, Camera Control was a hot mess when it debuted last year because I was either using on-screen controls or the new button. That’s why room for more personalization and customizability has been a game-changer. I realized I could access on-screen toggles while adding hidden settings to one-tap access. On my iPhone 17 Pro, I now use the Camera Control to open my payments app, adjust Exposure and Styles as well as trigger Visual Intelligence when needed.
