Do we live inside or on top of the earth?
Instead of saying that humans live on the outside surface of a hollow planet—sometimes called a “convex” Hollow Earth hypothesis—some have claimed humans live on the inside surface of a hollow spherical world, so that our universe itself lies in that world’s interior..
Is Earth the only planet with life?
Earth is the only planet in the universe known to possess life. The planet boasts several million species of life, living in habitats ranging from the bottom of the deepest ocean to a few miles into the atmosphere. And scientists think far more species remain to be discovered.
What is our Earth shape?
ellipsoidThe Earth is an irregularly shaped ellipsoid. While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid.
Why do we live?
We live because there are people who love us, and people we love back. We live because we want to find out things, and learn, and become able to do things that we would like to do. We live because others want us to, and we want them to live along with us. We live because we have hope, and want to see what happens next.
How long will universe last?
Assuming that dark energy continues to make the universe expand at an accelerating rate, in about 150 billion years all galaxies outside the Local Supercluster will pass behind the cosmological horizon.
What’s the thinnest layer of the earth?
crustThe crust is what you and I live on and is by far the thinnest of the layers of earth. The thickness varies depending on where you are on earth, with oceanic crust being 5-10 km and continental mountain ranges being up to 30-45 km thick.
Is there water under earth?
The finding, published in Science, suggests that a reservoir of water is hidden in the Earth’s mantle, more than 400 miles below the surface. Try to refrain from imagining expanses of underground seas: all this water, three times the volume of water on the surface, is trapped inside rocks.
Which is correct on Earth or in Earth?
“In the earth” emphasizes the former, “in earth” the latter. The phrase “in earth” does not necessarily mean the same as buried beneath the soil. The phrase is used in the Lord’s Prayer (KJV) (“Thy will be done in earth, as it is in heaven”, though most people, even serious Christians, misquote it as “on earth”.
How do we live on Earth?
A special planet: the habitable Earth What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
Are we on the surface of the earth?
The surface of the planet, where we live, is called the crust—it’s actually a very thin layer, just 70 kilometres deep at its thickest point. … Without it, we wouldn’t have volcanoes, earthquakes … and actually, Earth wouldn’t be able to sustain life.
Will the universe end?
Theories about the end of the universe. The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the “Big Freeze” scenario below.
How old is the earth?
4.543 billion yearsEarth/Age
Who created the universe?
In his 1988 book, A Brief History of Time, Hawking had seemed to accept the role of God in the creation of the universe. But in the new text, co-written with American physicist Leonard Mlodinow, he said new theories showed a creator is “not necessary”.
Why is life possible only on Earth?
All living things on earth have adapted to our atmosphere, which means all living things need our mix of atmospheric gases. Life elsewhere would be specifically adapted to their own conditions. Water is a really important ingredient to sustain the kind of life we know on Earth.
In which part of the earth do we live?
crustThe crust is the outermost layer of Earth, and it is the one we live on. You can think of the crust as a thin shell that covers the earth.
Where does space end?
No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.
How was Earth created?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.
