So that the life exists on a planet, there must be conditions that allow it. Among the main reasons, the large land They are not strictly necessary, but they are not excessive, and they can help this amazing event grow. Therefore, the discovery that billions of years before the birth of our planet already exists exoplanets in this galaxy that gives way to the continental fragments is surprising.
The latter is new research led by Cardiff University (United Kingdom). In addition, the scientists responsible maintain that this will increase the chances of life on exoplanets along the Milky Way.
Life beyond Earth
Planning for this possibility was considered long before this conclusion was reached. In fact, its existence is what inspires it Jane Greavesa stronomer of Cardiff University to investigate when the first continents of our galaxy.

The thing is not there. A work like the one now published in Research Notes of the American Astronomical Society He not only bet on life, but on smart and advanced version this.
If life on another planet had a five-billion-year head start, “it could host life more advanced than ours,” Greaves wrote in the aforementioned study.
Indeed, the researcher found that The first continents were formed by exoplanets orbiting stars similar to the Sun. Specifically, these Earth masses were formed at least 2 billion years before plate tectonics began in our world.
Greaves based on your sample of 29 stars considers that at least two systems in the Milky Way may have biospheres more advanced than that of the Milky Way. Earth.
