  It's very strange to hear that negative mass exists. All the objects which  exists on the earth has positive mass. Rather we says that, matter is anything which has mass and occupies space. All  the objects on the earth are made up of matter. It's interesting to know then, 'How negative mass occurs???' Negative Mass : Negative Mass is the mass whose sign of the mass is opposite to the mass of the normal matter. Actually when we push something that object has tendancy to move, which says that the object has positive mass. If the object has negative mass, if you push it then gets accelerates towards you. Example.  -2 kg. Then how negative mass occurs??  There are three criteria's from which the sign of the mass is decided. Positive Mass : The objects who travels at the speed slower than the speed of light, have positive mass. All the objects slows very slowly compared to the speed of the light. Zero Mass : The objects who travels at the speed of light, have zero...

WhatsApp vs Signal vs Telegram: Here’s how they fare against each other amidst concerns of privacy after WhatsApp’s latest policy update "> Privacy policy changes made by Whatsapp pushes users to look at alternatives like Signal and Telegram Earlier this week, Whatsapp forced its users to agree to the new privacy rules or else lose access to the app. An in-app notification popped up as soon as the app was opened and it informed users on the changes made in the new privacy policy. According to the popular messaging app, the company’s new terms of service and privacy policy will come into effect on 8 February 2021. To continue using the app, WhatsApp users will have to accept the terms and conditions. If the users do not accept the new terms of service, they will lose access to the app. In other words, updated policy no longer indicates that users would be able to choose whether they want their data to be shared with Facebook or not. In its notification, the Facebook-...

The Oort Cloud is the most distant region of our solar system. Even the nearest objects in the Oort Cloud are thought to be many times farther from the Sun than the outer reaches of the  Kuiper Belt . Unlike the orbits of the planets and the Kuiper Belt, which lie mostly in the same flat disk around the Sun, the Oort Cloud is believed to be a giant spherical shell surrounding the rest of the solar system. It is like a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger. The Oort Cloud might contain billions, or even trillions, of objects. Home of Comets Because the orbits of long-period comets are so extremely long, scientists suspect that the Oort Cloud is the source of most of those comets. For example, comet C/2013 A1 Siding Spring, which made a very close pass by Mars in 2014, will not return to the inner solar system for about 740,000 years. The distance from the Sun to the Oort Cloud is so enormous that it’s usef...

In Brief Both  Arrokoth  (recently visited by NASA's New Horizons mission) and  Pluto  are in the Kuiper Belt — a donut-shaped region of icy bodies beyond the orbit of Neptune. There may be millions of these icy objects, collectively referred to as Kuiper Belt objects (KBOs) or trans-Neptunian objects (TNOs), in this distant region of our solar system. Similar to the asteroid belt, the Kuiper Belt is a region of leftovers from the solar system's early history. Like asteroid belt, it has also been shaped by a giant planet, although it's more of a thick disk (like a donut) than a thin belt. The Kuiper Belt shouldn't be confused with the  Oort Cloud , which is a much more distant region of icy, comet-like bodies that surrounds the solar system, including the Kuiper Belt. Both the Oort Cloud and the Kuiper Belt are thought to be sources of comets. The Kuiper Belt is truly a frontier in space -- it's a place we're still just beginning to explore and our understanding...

Our Solar System Sun Facts The Sun is the largest object within our solar system, comprising 99.8% of the system’s mass. The Sun is located at the center of our solar system, and Earth orbits 93 million miles away from it. Though massive, the Sun still isn’t as large as other types of stars. It’s classified as a yellow dwarf star. The Sun's magnetic field spreads throughout the solar system via the solar wind. Quick Take The Sun—the heart of our solar system—is a yellow dwarf star, a hot ball of glowing gases. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest particles of debris in its orbit. Electric currents in the Sun generate a magnetic field that is carried out through the solar system by the solar wind—a stream of electrically charged gas blowing outward from the Sun in all directions. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and aurorae...

Our Solar System Why Is It Called The "Solar" System? There are many planetary systems like ours in the universe, with planets orbiting a host star. Our planetary system is named the "solar" system because our Sun is named Sol, after the Latin word for Sun, "solis," and anything related to the Sun we call "solar." Our planetary system is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids. Beyond our own solar system, we have discovered thousands of planetary systems orbiting other stars in the Milky Way. 10 Need-to-Know Things About the Solar System ONE OF BILLIONS Our solar system is made up of a star, eight planets and countless smaller bodies such as dwarf planets, astero...

Does Weather Affect Cell Service ?         Could rain, snow, hot or cold weather affect your cell phone signal? Cellular network traffic is carried on radio waves, and so cell reception can be affected by any atmospheric condition that might similarly affect a terrestrial radio signal. In fact, weather can have a direct or an indirect effect on 4G cell signal, but won’t really affect cell signals under 2GHz. An example of a  direct effect  would be a thunderstorm when lightning causes electrical interference with cell signals. An  indirect effect  of weather on cell reception could be caused by a change of season, say from winter to spring. For example, in a single-story home or office building surrounded by trees, this could mean better indoor cell reception in winter when bare trees are less of an obstacle to incoming and outgoing signals. With the coming of spring, the surrounding trees bud out and then produce leaves. This increased foliage ca...
