Once we exhaust Earth's resources, there is going to be a war over materials. Recycling will be drastically more enforced, and we will most likely use the recycled materials to leave Earth and find a new home. We would completely destroy Earth, therefore it's unhabitable.

How far do you have to travel in order to leave the earths atmosphere and go into space?

The boundary between Earth's atmosphere and outer space is defined by the Kármán line, which is at an altitude of 100 kilometers (62 miles) above sea level. To officially leave Earth's atmosphere and reach space, you would need to travel at least this distance vertically.


Will a spaceship need more or less energy to take off from the moon than the earth?

A spaceship would need less energy to take off from the Moon compared to the Earth due to the Moon's lower gravity. The Moon's gravity is about 1/6th that of Earth, so a spacecraft would require less thrust to overcome gravity and achieve liftoff.


How many rulers would you need to go around the Earth 3 times?

Do you need a moon constellation map on the moon?

No, a moon constellation map would not be needed on the moon because constellations are patterns of stars as seen from Earth. The moon's lack of a substantial atmosphere also means that stars would appear much brighter and clearer without the need for a map.


Would it be easier to lift a truck on the moon or on the earth?

It would be easier to lift a truck on the moon because the moon has weaker gravity compared to Earth, approximately 1/6th of Earth's gravity. This means you would need to exert less force to lift the same truck on the moon than on Earth.

How fast would the earth have to rotate to be noticeable?

The Earth would need to rotate at a speed faster than its current rotation, approximately 1100 mph (1700 km/h) at the equator, for humans to noticeably feel the change. However, such a rapid rotation speed would have catastrophic consequences on Earth's ecosystem and atmosphere.
