Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events as measured by observers situated at varying distances from a gravitating mass. The lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational potential increases (the clock getting away from the source of gravitation). Albert Einstein originally predicted this effect in his theory of relativity and it has since been confirmed by tests of general relativity.[1]

Mariana Trench, also called Marianas Trench, deep-sea trench in the floor of the western North Pacific Ocean, the deepest such trench known on Earth, located mostly east as well as south of the Mariana Islands. It is part of the western Pacific system of oceanic trenches coinciding with subduction zones—points where two adjacent tectonic plates collide, one being forced below the other. An arcing depression, the Mariana Trench stretches for more than 1,580 miles (2,540 km) with a mean width of 43 miles (69 km). The greatest depths are reached in Challenger Deep, a smaller steep-walled valley on the floor of the main trench southwest of Guam. The Mariana Trench, which is situated within the territories of the U.S. dependencies of the Northern Mariana Islands and Guam, was designated a U.S. national monument in 2009.

As global tensions continue to simmer, one cannot help but wonder, "what would happen if World War 3 started?" Although it's a chilling thought, being aware of the potential consequences of such a catastrophic event might help us better understand the importance of preserving peace and seeking diplomatic solutions. In this blog post, we'll delve into the grim possibilities that could arise if humanity were to face a third world war and explore its impact on various aspects of our lives

There have been five big mass extinctions in Earth’s history – these are called the ‘Big Five’. Understanding the reasons and timelines of these events is important to understand the speed and scale of species extinctions today. When and why did these mass extinction events happen?

On a clear night, staring up at the stars induces a sense of simultaneous wonder and insignificance. Humanity time and time again finds itself lost amid the vastness of a universe that we are still struggling to understand. There are many questions we ask ourselves when looking toward the heavens, but one of them always feels just outside of our grasp: Across all the billions of light-years of starry sky above us, could we possibly be the only life? Scientists have explored this question for years. In 1961 physicist Frank Drake developed a mathematical equation to help solve it: N = R*fpneflfifcL

GJ 667 C c is a super Earth exoplanet that orbits an M-type star. Its mass is 3.8 Earths, it takes 28.1 days to complete one orbit of its star, and is 0.125 AU from its star. Its discovery was announced in 2011.

If Earth stopped spinning all at once, it would be enormously catastrophic for much of the planet’s surface. Though we don’t feel it, we’re all moving along with the planet as it rotates; at the equator, this works out to around 1,000 miles per hour. Stop the planet suddenly, and everything sitting on top of it would go flying eastward. Imagine people, houses, trees, boulders and more being launched sideways at hundreds of miles an hour. In the aftermath, high speed winds, still rotating nearly as fast as the planet, would scour the surface clean.

The ocean covers approximately 70% of Earth’s surface. It’s the largest livable space on our planet, and there’s more life there than anywhere else on Earth. Consider the size of the ocean. Its surface area is about 360 million square kilometers (139 million square miles), and its average depth is 3,682 meters (12,080 feet). Throughout these depths, there is life. Despite its importance, the majority of our ocean is largely unknown. However, through exploration, we’re learning more about its biological, chemical, physical, geological, and archaeological aspects. Exploration leads to discovery, but before we can truly explore, we must map.

Around 75% of Earth's animals, including dinosaurs, suddenly died out at the same point in time. So how was this global mass extinction caused by a rock hurtling into the coast of Central America? Paul explains, 'The asteroid hit at high velocity and effectively vaporised. It made a huge crater, so in the immediate area there was total devastation. A huge blast wave and heatwave went out and it threw vast amounts of material up into the atmosphere. 'It sent soot travelling all around the world. It didn't completely block out the Sun, but it reduced the amount of light that reached the Earth's surface. So it had an impact on plant growth

The key idea of the video is that embracing the Fifth Dimension involves letting go of old aspects of life, prioritizing mental health, aligning with one's purpose, and cultivating purposeful connections in order to live in a state of love, unity, and spiritual awakening.

We talked briefly about real-life and hypothetical AI risks above. Below, we’ve outlined each in detail. Real-life risks include things like consumer privacy, legal issues, AI bias, and more. And the hypothetical future issues include things like AI programmed for harm, or AI developing destructive behaviors. Real-life AI risks There are a myriad of risks to do with AI that we deal with in our lives today. Not every AI risk is as big and worrisome as killer robots or sentient AI. Some of the biggest risks today include things like consumer privacy, biased programming, danger to humans, and unclear legal regulation.

We don't normally think of plants as particularly scary organisms. But this rather entertaining Reddit thread from 2016 will make you reconsider that assumption. "Botanists of reddit, what are the scariest plants in the world?" user Zipzapadam asked. And Reddit delivered. We're not talking about common poison ivy or run-of-the-mill carnivorous plants. Some of these plants could actually kill you.

A claim by researchers that complex life on Earth may have evolved a billion years earlier than previously thought has immediately divided scientists in the field, with some hailing the evidence as rock-solid and others unconvinced. The researchers, writing in the journal Nature Communications, said they had uncovered fossils showing that complex life on Earth began more than 1.5bn years ago.

Floods can happen for several reasons, many of which coincide. However, excessive and heavy rainfall is one of the leading causes of floods, mainly when flash floods occur. Floods occur when the rate of rain in low-lying areas and urban settings exceeds the capacity of the ground to absorb it. Extreme rainfall in river courses also contributes to flooding. This is because it causes water to flow down riverbanks and spill over onto adjacent land.

Do aliens exist? This is a really interesting question and one that NASA has been trying to understand, explore, and figure out for a long time. We have not yet discovered life on any other planet, and we have not seen any scientifically supported evidence for extraterrestrial life. But if we think about life on this planet, beyond the big things — the elephants, the whales, redwoods trees –– and focus on the tiny things, nearly everywhere on Earth that we’ve looked, we’ve found microbial life.

Oxygen is the lifeline of a human being. It is the main catalyst for intracellular energy that is necessary to sustain human life. We inhale oxygen and exhale carbon dioxide. But have you ever thought that what would happen if the world lost the oxygen for just five seconds? What would we do? Would we just hold our breath for five seconds? And what would happen to the atmosphere? How will the loss of oxygen affect the environment?

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon. Although the rocks that record the earliest parts of Earth’s history have been destroyed or deformed over time by more than four billion years of geology, scientists can use modern rocks, moon samples, and meteorites to figure out when and how the Earth and moon formed, and what they might once have looked like.

Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh.Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion.[1

Butterfly Life Cycle The butterfly and moth develop through a process called metamorphosis. This is a Greek word that means transformation or change in shape. Insects have two common types of metamorphosis. Grasshoppers, crickets, dragonflies, and cockroaches have incomplete metamorphosis. The young (called a nymph) usually look like small adults but without the wings. Butterflies, moths, beetles, flies and bees have complete metamorphosis. The young (called a larva instead of a nymph) is very different from the adults. It also usually eats different types of food. There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.

Over the coming years and decades, the explosive rise of technology and artificial intelligence (AI) is set to revolutionise our lives, society, and even our deaths. We picked the brains of our resident AI expert, Head of Business and Computing Dr Ajaz Ali, to learn more about the exciting, useful – and perhaps a little bit scary – ways that things could be different by 2050.

Octopuses are sea animals famous for their rounded bodies, bulging eyes, and eight long arms. They live in all the world’s oceans but are especially abundant in warm, tropical waters. Octopuses, like their cousin, the squid, are often considered “monsters of the deep,” though some species, or types, occupy relatively shallow waters.

Wildlife habitat is the natural environment of a plant or animal and can be considered an output or product of forest and natural resource management.

If the Moon fell into the Earth the collision would break the Earth immediately into large chunks as it joined with and merged with the moon that is show in this video.
