What if our planet became super-earths?

super-earths — a unique class of planets, whose masses range from two to ten Earth masses

Since the discovery of the first exoplanet some 30 years ago, scientists were able to locate over 4,000 celestial objects are different from each other in size and characteristics. Among the objects found in other solar systems, scientists were able to identify a huge number of planets whose sizes and masses are several times higher than those of the Earth. However, despite its similarities with the blue planet, super-earths are also some significant differences that call into question any possibility of the them any life. But what would happen if our planet suddenly became ?

How to look super-earths?

Planet, whose size is somewhat greater than that of earth, in many ways may resemble ours: they have rocky, hard surfaces, often located close to their stars and thus have a relatively thin atmosphere. However, that is where the similarity ends unexpectedly. Mickey Rosenthal, a doctoral student studying planetamazon at the University of California Santa Cruz, believes that the process of conversion of Land into super-earths in the early stages of its development could interfere with the Jupiter, which in time cut the planet access to space building blocks. The appearance of a giant planet in the immediate proximity from us are literally forced to “starve” while still very young Earth, writes the portal .

However, the absence of Jupiter, and, consequently, increasing the size of our planet directly would have affected all the inhabitants of the Earth. So, absolutely everything on the planet — mount Everest, trees, animals and even you — it would be noticeably shorter in size. The fact that with increasing size of the planet increases, gravity. If the Earth was twice the size, your weight would have increased by 2 times simply because gravity would attract you twice as hard. In order to be able to resist the gravitational pull in this case, we would have had to use twice as much energy, so all modern high-rise buildings would have just collapsed under the impact of the new gravity.

Due to the presence of a stronger gravitational field, the Earth would be faced with the increased threat of fall of a large meteorite that would clearly have worsened the living conditions on the planet. In the case if a hypothetical super-earth, and grew tenfold in size in its depths could begin dramatic changes that could affect the planet. Iron core and liquid mantle place that we believe home would have been 10 times more and more under the influence of gravity would increase and the pressure under the surface of the planet. So much “bloated” would simply lose its magnetic field due to the solidification of the liquid iron core at the center of our planet.

the Earth's Magnetic field protects life on the planet from the deadly charged particles from outer space causing cleavage of the DNA of a living organism

The Presence of large internal parts could make the planet more volcanically active than it is now. With increasing radius in the bowels of the planet would remain more energy and less room for its release. In such a world, powerful volcanoes will not seem something amazing, but local would obviously not lucky enough to appear in such a hazardous place.

Based on the supersense, which scientists have discovered to date, we cannot be sure that a few of the larger Earth would be habitable. Perhaps it would simply be flooded with water. So, a large number of officially recognized “water worlds” without the availability of any hard surface.

If the Earth were larger in size, it could turn into a completely flooded world

Almost bottomless oceans “water world” may be uninhabitable due to the fact that the ice formed in the lower layers of the global ocean is under the influence of extremely high pressure blocks any interaction between the atmosphere and the bowels of the planet. The lack of carbon and mineral cycle in such a world, is not conducive to habitability — at least for life as we know it.

Anyway, the reality is that scientists still have more questions about supersense than answers. So, we still do not fully understand the physics of our own planet that day by day gives us more and more mysteries about their internal structure and processes occurring in the bowels of the Earth. In this case, how can we be sure that happens over many millions and billions of miles away from us?
