Scientists simulate how extraterrestrial astronomers will view the Milky Way.

What might extraterrestrial scientists in a faraway galaxy discover if they pointed their telescopes at the Milky Way?

One of the eight planets circling one of the hundreds of billions of stars in the Milky Way galaxy, one of the hundreds of billions of galaxies in the observable universe, is all that we care about, all that we comprehend, and all that we can sense. Perhaps an extraterrestrial entity is observing the Milky Way where we are located from a galaxy far, far away. Which will they witness?

That is the same question that scientists posed when they imagined what extraterrestrial astronomers seeing the Milky Way from a great distance would discover if they examined the galaxy's chemical makeup.

Turn the telescope around

To understand how aliens will see our galaxy, it would perhaps be prudent to first understand how we see distant galaxies. Our telescope observations show us a galaxy’s shape and its “spectrum,” which is the sum of the parts that make up the light from the galaxy.

Astronomers on Earth have devised some cunning ways to determine the characteristics of a distant galaxy by studying the scant light that we receive from it. Therefore, we may assume right once that an intelligent extraterrestrial civilization will use equally advanced techniques to observe the Milky Way.

Here is what I think of the Motorola Razr 40 Ultra as someone who often uses a flip phone.

With a large exterior screen and a quirky design, the Motorola Razr 40 Ultra provides a novel and intriguing take on flip-style foldable smartphones.

My decision to use the Nokia 2660 Flip as my secondary phone was only an amusing experiment. I was seeking for a flip phone to scratch my old tech craving. The Nokia 2660 Flip has been around for a year now, and its attractiveness as a throwback phone has not diminished in the slightest. It has only expanded. The Motorola Razr 40 Ultra, a new premium foldable smartphone in the clamshell form that significantly draws inspiration from the legendary Razr V3, appears to be built around that attraction. The Razr 40 Ultra also embraces the modern linked environment in which we live in close proximity to our smartphones. In my opinion, Motorola is connecting with its past while moving towards the future.

I had a brief interaction with the Motorola Razr 40 Ultra during its debut, and these are my initial thoughts on it.

I think the Razr 40 Ultra's design is very gorgeous. The model with the vegan leather back in ruby red, especially the one I saw in a Motorola executive's hands, looks opulent. The Razr 40 Ultra is extremely thin, measuring only 7.58mm when unfurled, while being broader than the original. The huge chin of the original Razr design is also gone when the phone is opened up. That was the distinctive design element of Razr. The Razr 40 Ultra currently resembles every other flip-style foldable smartphone available.

Meta competes with Twitter by using the competing microblogging service Threads.

 In more than a hundred nations, Threads is available for free download through the Google Play Store and the Apple App Store.

The business claims its new microblogging service, called Meta, is Instagram's "text-based conversation app." Meta debuted the service on Thursday. Threads is viewed as a direct competitor to Twitter, which has undergone significant changes since Elon Musk acquired the company and has witnessed a large influx of people moving to alternatives like Bluesky and Mastodon.

In more than a hundred nations, Threads is available for free download through the Google Play Store and the Apple App Store. Users may send brief messages on the text-based social messaging app, and other users can like, share, and comment on them. Posts may contain up to 500 characters, links, images, and videos that are no longer than five minutes.

Everything you need to know about the newest Twitter competitor, Instagram Threads

Because the app is based on the Instagram network, users may easily reuse their Instagram login. It automatically follows the Instagram users you already follow. You may also personalise your Threads profile on Meta.

Meta said earlier this year that it was developing a text-based platform. Bluesky, Mastodon, and Twitter are supported by Meta's Threads. Users may share text, images, and videos with their followers on all of those networks. The social media behemoth claimed that Threads was created "with tools to enable positive, productive conversations," and users would have control over who mentions them or replies to them within the programme.

Why is there a 'gravity hole' in the Indian Ocean, exactly?

The enigmatic "gravity hole" in the Indian Ocean may have an explanation, according to researchers from the Indian Institute of Science.

Although it is simple to picture the Earth as a flawless sphere with constant gravity, that is far from the truth. Contrary to popular belief, our world bulges near the equator and is flat at the poles. Its gravity isn't constant throughout, either. For instance, researchers have finally discovered why there is a significant "gravity hole" in the Indian Ocean.

It may be easy to imagine the Earth as a perfect sphere with constant gravity, but that is far from the reality. Contrary to common assumption, our earth is flat at the poles and bulges at the equator. Even its gravity fluctuates over time. For instance, scientists have now determined the cause of the large "gravity hole" in the Indian Ocean.

The Indian Ocean Geoid Low (IOGL) was first identified in 1948 by Dutch geophysicist Felix Andries Vening Meinesz during a study of the ocean. Since then, it has been supported by more ship-based research and satellite-based observations. However, scientists haven't really been able to establish definitively why it occurs. Up till this point.

USB drive explosives refocus attention on protecting businesses' back doors from "phygital attacks."

 A physical attack might create havoc and result in severe injuries if you're not careful. Veteran of the US Army Will Plummer highlights the dangers of physical attacks and how businesses may protect themselves.

Lenin Artieda, an Ecuadorian journalist, thought March 20 of this year was just another Monday. But normalcy wouldn't last for very long. He received a parcel addressed to him with a little USB drive inside. He unwrapped the disc and connected it into his computer without giving it a second thought. The gadget blew up, hurting the journalist. 

Authorities in Ecuador launched a terrorist probe as a result of the event. At least five more similar envelopes were mailed to Ecuadorian media outlets around the same time, proving that this was not an isolated event. These unnerving episodes of explosive USB drives targeting journalists in Ecuador have created a new vista in the global danger landscape: physical attacks. This is because the physical and digital worlds are fast converging. 

When a gadget, such a USB stick or small computer, is used to start a cyberattack and uses a physical point of entry, the assault is said to be "phygital." "In this case, a digital device was used to mask a physical threat, but it could have just as easily been the target of a cyberattack," says Will Plummer, a 25-year US Army veteran who serves as the Chief Security Officer for RaySecur, a company that develops next-generation mail screening technology.
