Scientists suggest injecting living microbes into galaxies with the help of laser impulses

Experts plan to use a small semiconductor probe with a margin to protect it from radiation during work.

A team of scientists is proposing to launch microbes living in miniature ‘ships’ into galaxy to study their behavior from Earth, they say. Article Acta was published last month in Astronautica magazine.

The micro-organisms will fly into space within a small semiconductor probe The size of a human handOr even smaller, it is provided with a boundary that protects it from radiation as it passes through the galactic medium.

To carry out these missions beyond the solar system, researchers recommend using the technology they now work with, which uses light as a “stimulus” and allows it to “push macroscopic objects at speeds close to the speed of light.” To explain Philip Lupine (UCSB) is a professor at the University of California at Santa Barbara and co-author of the study.

Goes to the nearest star

Interstellar Prop: A new mission proposed by scientists to travel outside the solar system

The probe, which will carry internal instruments to locate, collect and transmit data to the Earth, will be propelled up to 20-30% of the speed of light, using an impulse laser mounted on Earth or even the Moon.

In this way, experts calculate that the ‘mini-ship’ speed can be reached Speeds in excess of 160 million kilometers per hourSo that it can reach the red dwarf star Proxima CentauriVery close to our solar system, in about 20 years.

Within these vessels they will introduce micro-organisms, such as kenoraptidis elegans or tardigradesCommonly known as water bears, they were the first Earthlings to travel between galaxies.

“Trained Behavior”

They discovered the first black hole to orbit freely in the galaxy

The aim of the mission is to accurately monitor the creatures from the earth with the help Photon contact To find out the effect of interstellar travel on them. In this way, they seek to explore what potential effects of these trajectories could have on humans, although they have realized that sending people into galactic space is still a long way off.

“We can explore how they remember trained behavior when they fly at speeds close to the speed of light from their terrain. Examine your metabolismPhysiology, Neurological Function, Reproduction and Aging, “said Joel Rothman, Lupine’s colleague at UCSP and co – author of the research.

In this sense, the scientist assures that most of the experiments that can be carried out with these animals in the laboratory can also be carried out in small spacecraft as they travel through the universe.
