Do aliens exist?
Back to question

Detection or contact with an alien life form is not possible

< (4 of 4)

Technical means do not allow detection of alien life

Our current technology does not allow detection of an alien life.
< (2 of 2)

Context

With current technology we can only prove if a planet is in a habitable zone but not if it can actually harbour intelligent life.

The Argument

Possibile method of detecting life on an exoplanet: - Detection of sign of life on planet (such as river, cities, manufacts) requires an image of planet: this would require an impractical optical resolution of a telescope positioned in the Solar System). - Sending a probe on an outer solar system is also highly impractical (length of travel). - Detection of signals form an alien life is impractical (see also SETI argument)

Counter arguments

Some missions to our next Solar System can be physically feasible as Breakthrough Starshot [1] According to Kardashev scale [2] level II or III civilisations can be able to harness such high amount of energies that should be detectable on Earth.

Premises
