Earth travels 18 1/2 miles through space, and the International Space Station travels 5 miles around us. In that same second, an unbelievable 20,000 cans of Coca-Cola are sold, along with 9 iPhones. 4 thousand stars are born across the universe. 60 sets of this happen every minute, and then 60 sets of that every hour, and then 24 hour-long sets every day…that gives us 86,400 seconds in a day, and more than 31 million seconds in a year.

If human beings were to achieve immortality, there would most likely be a change in the world's social structures. Sociologists argue that human beings' awareness of their own mortality shapes their behavior.

If for any reason the Sun shrank smaller than the Earth, this shrunken Sun wouldn't have the mass to create fusion and would burn out completely. Our solar system would lose its only star. ... Earth's mass would be at least 333,000 times bigger than it is now. Imagine the gravity that planet would have.

If the core were to cool completely, the planet would grow cold and dead. ... Cooling also could cost us the magnetic shield around the planet created by heat from the core. This shield protects Earth from cosmic radiation. The shield is created by a convection process caused by constantly moving iron.

Everyone will end up either at the bottom of walls, rocks or holes or sliding around. Unable to move and slowly dying through lack of water or dying from broken bones. If earth suddenly lost friction we'd all die in massive earthquakes and tsunamis as all the pent up tectonic energy everywhere is released at once

Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.

The earliest known life-forms on Earth are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth

If we put it near the Earth, the ocean would just fall back down into the atmosphere. As it fell, it would heat up and turn to steam, which would condense and fall right back into the ocean as rain.

The discovery that the atmosphere of Venus absorbs a precise frequency of microwave radiation has just turned planetary science on its head. An international team of scientists used radio telescopes in Hawaii and Chile to find signs that the clouds on Earth’s neighbouring planet contain tiny quantities of a molecule called phosphine.

Jupiter would be massive enough to become a red dwarf – a small, cool, hydrogen-burning star. ... Because Jupiter is four times further away from us than the Sun, 588 million kilometers away, the Earth wouldn't get much heat from it. By and large, Jupiter turning into a red dwarf wouldn't change anything for life on Earth
