How to Know if You've Been Hacked? If you think your smartphone is your private zone, you may be very wrong. So far, there is no such device that can’t be hacked.

We often see our smartphones as our secure digital havens. We use them to keep our most personal information: from pictures to credit card details. Some people even save their passwords in Notes. That’s a bit too much, right? You probably have all your text and email communication, including work stuff, based or synchronized on your phone.

To reduce the potential risks, we figured out three things: the ways your phone can be hacked, how to recognize them, and how to protect your phone from hackers.

Why do airlines avoid the Pacific Ocean? You might think it was a safety issue. The Pacific is the largest and deepest of the world’s oceans. If a plane encounters a problem over a seemingly endless and bottomless pond of water, the pilots are going to have a rough time finding a safe spot to set her down.

Guessing that it is a safety precaution wouldn't be entirely wrong. When planning a route, many pilots prefer to maximize the number of airports along their path. Emergencies are incredibly rare relative to how many planes take to the skies every day. That said, it isn’t the main reason airlines tend to avoid making a straight shot east to west...

How large was the iceberg that sank the Titanic? Months before the disaster struck, a ginormous chunk of ice had broken away from a glacier in southwest Greenland. It was made of the snow that had fallen about 100,000 years ago - when mammoths were still roaming the planet. And when the iceberg just started its journey, it was a huge thing. Almost 1,700 ft (518 m) long, it also weighed 75 million tons! 

Even after melting into the water for months, the iceberg still weighed an impressive one and a half million tons. Its top part was towering over the water for almost 100 ft (30m). But what people saw was just a tiny part of a jumbo piece of ice. The largest part of any iceberg is hidden under the surface, with a mere one-tenth visible above the water. "The Titanic iceberg" wasn't an exception. The moment the ship collided with it, the vessel was doomed. But what if what we know about the disaster is not true? What if it had been the Kraken that sank the Titanic? A legendary creature feared by everyone who sets off on a sea voyage...

We know that no supernovas, crashing asteroids, and burning planets make a sound in space. But what if you actually CAN hear something out there? We need some particles to create sound, but space is almost a perfect vacuum with no particles. But in fact, the "perfect vacuum" doesn't really exist as we can't get rid of atoms for good. So, can these atoms push each other and create vibrations and sounds? Let's find it out!

Have you ever noticed that you need to pull the window blind up, not down, to close it, in exit rows on most planes? It's designed so to help people quickly leave the plane in case of an emergency. Speaking of emergencies, turbulence isn't one of them as it's perfectly normal. But if you're still afraid of it, think of your plane as a napkin inside a pot of jelly. If you tap the jelly, the napkin will not fall anywhere.

Would you like to travel the world in a hot air balloon? You'd need a sound navigation system, a wealthy sponsor, and tireless endurance. Steve Fossett decided to do it in 1997. He managed to take off and cross the Atlantic Ocean on the 3rd attempt, but his plan failed while he was trying to fly over the Southern Hemisphere. In his sixth attempt, Fossett made it around the world in a hot air balloon: his 'Spirit of Freedom' balloon landed in Queensland, Australia, after a two-week flight across the globe. But then, the traveler mysteriously disappeared.

We're used to the fact that space is cold, but our Universe is actually getting hotter. Scientists found that the temperature of a gas in space has gone up more than 10 times in the last 10 billion years. There are many mechanisms that help to heat up the matter in the Universe, and they could go crazy if space warms up. Active stars, colliding galaxies, stellar cataclysms, black holes, neutron stars - the Universe has so many sources of energy. So, will this change in temperature lead to a catastrophe?
