What will the first encounter with aliens be like? Will it be something friendly like it happens with ET? Or will they want to take over the Earth’s resources like Independence Day? Nobody knows and, according to a scientific studythere is still a long way to go for that to happen.
A recent investigation claims to have an estimate of how long until we receive the first extraterrestrial contact, if we have not already had one and they have hidden it from us.
Although we feel alone in the immensity of the space we inhabit, it seems impossible that other civilizations do not exist. Only in the Milky Way, galaxy to which we belong, there are about 6 billion terrestrial planets.
Estimates after various scientific studies calculate that some 300 million worlds meet the conditions for the development of life as we know it. That only happens in the stellar cluster in which we are, because in addition, in the universe, there are about a hundred billion galaxies.
When do outside visitors come?
No one has visited or contacted us: What’s up? The scientific study, cited by National Geographic, says that according to their estimates the first contacts should arrive within about 400 years.
They do that calculation based on our technology, which the fastest it knows is the speed of light.
So, identifying the stars similar to our Sun that have been detected in the universe and assuming that they have a technological advance similar to ours (or perhaps a little better), the first signals have to travel hundreds or thousands of light years, therefore , so that we begin to receive the first ones – they say – there are about 400 years to go.
“Biotic planets (those that show signs of life) are very common in the universe, hence the supposed civilizations they might not be interested in exploring Earth. If they are located more than 100 light years away, it seems like just another planet, without a technological signature that shows that there are signs of intelligence,” said Amri Wandel, an astrophysicist at the Hebrew University of Jerusalem, in statements to National Geographic.
