A "New Earth" for Man. Just a dream, a fictional story or science that can be realized?

The search or research for a "new Earth" for humans turns out to be a real thing. NASA scientists have also designed many plans that might be realized.

A "new Earth" for humans to live in has long been a dream, and there are many fictional stories about it. But this also turns out to be something that scientists, especially NASA, want to realize. This plan is known as space colonization or planning for human habitation in outer space.

Stephen Hawking, a physicist from England, believes that this fragile Earth Earth will not be able to survive human habitation for another thousand years. Thus, a "new Earth" in outer space for human habitation is something that we want to realize.


Requirements for Space Objects to Become a "New Earth" for Humans

Many illustrations, plans and ways for humans to colonize outer space have been proposed by scientists. But of course, this requires a very, very big effort. Before discussing further the methods of space colonization by these scientists, here are several conditions so that any space object can become a "new Earth" for humans.

1. Water

Humans cannot live without water. Therefore, the space object that is planned to become a new human habitation is a place that must have water on its surface. Of course, with the right amount, not too much and not too little.

2. Ultraviolet

Objects nominated to be "new Earth" must emit ultraviolet radiation in the right proportions. Sufficient ultraviolet radiation is needed to form ozone. Of course, ozone will protect humans from potential dangers from outer space.

3. Stable

The space object must also be stable so that it can support life within it. Or maybe it can also create its own life. Based on research, stable space objects are those that have been formed over billions of years.

4. Sufficient Mass to Volume Ratio

What this means is that the right mass and volume ratio increases the possibility of an atmosphere forming. A small ratio will not be enough to form an atmosphere. Meanwhile, the atmosphere is very important to protect life within the object from space attacks in the form of energy (radiation) and matter (meteors).

5. Chemical Elements

Objects that are candidates for "new Earth" must also have four chemical elements or vital elements for human life on Earth Earth today. The four vital elements are carbon, hydrogen, oxygen and nitrogen.


So, a "new Earth" to be used as a place for humans to live in outer space is a human dream that has continued into fictional stories and is still an obsession to this day to be realized. Of course, this obsession was accompanied by active research and hard work from scientists and everyone involved in the project.
