How long would we survive if the Sun exploded?
Within a few days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after. Within two months, the ocean's surface would freeze over, but it would take another thousand years for our seas to freeze solid.
Can we survive the Sun exploding?
When the Sun does cease to exist, it will first expand in size and use up all the hydrogen present at its core, and then eventually shrink down and become a dying star. All human and plant life on Earth will eventually die out if the Sun explodes.
What year will the Sun explode?
After the sun has burned through most of the hydrogen in its core, it will transition to its next phase as a red giant. At this point roughly 5 billion years in the future, the sun will stop generating heat via nuclear fusion, and its core will become unstable and contract, according to NASA (opens in new tab).

How long will the 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.
How many years till the world ends?
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.
Will the Earth be destroyed by the sun?
Earth exists thanks to our sun, having formed in orbit around it from a huge cloud of gas and dust in space, 4.5 billion years ago. Likewise, the sun will ruin Earth for living things, some 5 billion years from now. As the sun evolves, it'll expand to become a red giant star and fry our planet to a cinder.

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.

What will happen in 1 googol?
The universe will die. Eventually it will become nothing. In roughly a quadrillion years, a last star will give its last twinkle, and black holes will devour everything before they completely evaporate. And in a googol years (that's 10 to the hundredth power, which is a lot), the universe will be empty.

How long will the earth last?
Take a deep breath—Earth is not going to die as soon as scientists believed. Two new modeling studies find that the gradually brightening sun won't vaporize our planet's water for at least another 1 billion to 1.5 billion years—hundreds of millions of years later than a slightly older model had forecast.

What will happen to Earth in quadrillion years?

What would happen if we had no gravity for 5 seconds?
Without gravity, the pressure of the Earth's inner core will cause the planet to expand. It's not like five seconds without gravity would cause the world to explode, but even a five-second expansion of the Earth's inner core would cause some major earthquakes, and trigger huge volcanic eruptions.
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.
What will happen to Earth in 1 billion years?
In about one billion years, the solar luminosity will be 10% higher, causing the atmosphere to become a "moist greenhouse", resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics and the entire carbon cycle will end.

What if oxygen disappeared?
Without oxygen, there would not any fire and the combustion process in our vehicles would stop. Every mode of transport except electric would fail instantly. Planes flying high in the sky would fall on earth and millions of cars running on petrol and diesel would stop on the roads.
