What would happen if Earth lost its sun?
Without the Sun's rays, all photosynthesis on Earth would stop. All plants would die and, eventually, all animals that rely on plants for food — including humans — would die, too.

What would happen if the sun disappeared for 2 seconds?
Eternal night would fall over the planet and Earth will start traveling into interstellar space at 18 miles per second. Within 2 seconds, the full moon reflecting the sun's rays on the dark side of the planet would also go dark.
How long would humans live without the Sun?
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after.

Can we survive the Sun’s death?
In other words, it's extremely unlikely that life on any planet can survive the death of its sun — but new life could spring from the ashes of the old once that sun shrivels up and turns off its violent winds. So, the wind may be against us now, but one day it will be gone.
What if Earth had 100 moons?

Can you steal the Moon?
Not enough money, not enough means. To 'steal' the moon you need to disturb its orbit. To disturb its orbit you need a heavy enough mass, at a trajectory and timing precisely to go past the moon to veer it off its orbit. The only kind of mass to pull it off in that time frame is another moon, perhaps one of Jupiters.
How much longer will Earth last?
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.
How long will humans last?
Humanity has a 95% probability of being extinct in 7,800,000 years, according to J.
What year will the Earth be destroyed?
By that point, all life on Earth will be extinct. Finally, the most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.
What if the world is a cube?
As a result, all water, and indeed our own atmosphere would be drawn towards the centre of the faces. So the edges of the Earth would be barren rock with no atmosphere, and the centre of each face would play host to giant oceans and a very thick atmosphere, each region potentially with its own distinct ecosystems.

Who owns the Moon?
The short answer is that no one owns the Moon. That's because of a piece of international law. The Outer Space Treaty of 1967, put forward by the United Nations, says that space belongs to no one country.
Is China mining the Moon?
China became the first country to send a probe to the far side of the moon in 2019, and last year it became only the second nation after the US to land a rover on Mars.
Will humans go extinct in 2100?
Metaculus users currently estimate a 3% probability of humanity going extinct before 2100.
How the Earth will be in 2050?
By 2050, about 75% of the world population will be living in cities. Then there will be buildings touching the sky and cities will be settled from the ground up. Roads will be built up to several floors. And to move around, the buildings will be connected to the skywalk.
How long has Earth got left?
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.

What would happen if the world was a different shape?
The landscape along the Earth's edges would be rocky and barren, since all the water would be pooled at the center of each face. And the atmospheric quality along the Earth's edges and corners would be too thin – or non-existent – to support life.
What if the Moon exploded?
If the moon exploded, the night sky would change. We would see more stars in the sky, but we would also see more meteors and experience more meteorites. The position of the Earth in space would change and temperatures and seasons would dramatically alter, and our ocean tides would be much weaker.
Who is the owner of Earth?
Egalitarian Ownership is the view that the earth originally belongs to humankind collectively, in the sense that all humans, no matter when and where they are born, must have some sort of symmetrical claim to them.
Can you buy a planet?
No, people cannot legally buy planets, at least for now. There isn't any way to legally enforce a claim to a planet, and courts have rejected similar claims in the past. International law forbids countries from claiming any celestial body, meaning a nation cannot grant space real estate to its citizens.
Can I buy Moon dust?
You could try to buy the lunar dust collected by the Soviet space program, though there's reportedly less than a pound of it worldwide, and samples tend to sell for hundreds of thousands of dollars at auction.
Is there oil on the moon?
Instead of water, liquid hydrocarbons in the form of methane andethane are present on the moon's surface, and tholins probably make up itsdunes. The term "tholins" was coined by Carl Sagan in 1979 todescribe the complex organic molecules at the heart of prebiotic chemistry.
How long do humans have left?

What if Earth was a donut?
The overall climate on donut Earth would be similar to what we currently have on our round Earth. It would be colder in the polar regions, and warmer at the equator. But the weather would be a little more extreme, and could even make some parts of the planet inhospitable, due to storms and hurricanes.
