The Longest Experiment In History, Will Be Completed In The Year 2514

This microbiological project seems to break the record as a 500-year long experiment. The project started in 2014 and will be completed in 2514.

It still takes 495 years to find out the end result of the experiment. Of course some will wonder, why did it take so long?


According to scientists, the project wants to find out how long microbes can survive. This study is a project from the University of Edinburg. They put 400 bottles of bacterial Bacillus subtilis in a dry state to form spores (fine powder).

The bottle is then sealed tightly with tin to protect it from carbon radiation or cosmic rays that can cause DNA damage.

"Whether the microbes will survive or some will die first. This will be the longest scientific experiment ever made," said Ralf Möller, who led the study from the German Aerospace Center.

During the experiment, every two years (for the first 24 years), a set of bottles will be opened to see how the spores work. After the first 24 years, periodic inspections will be reduced once every 25 years to 2514.

In 2016, 1 bottle set was opened and the results were published. The storage for two years did not make any difference, the sample was also unaffected by the exposure to X-rays, ultraviolet rays, hydrogen peroxide, and high temperatures.


Checking these bacteria is easy. However, the hard part is to make sure someone will continue to do so well on schedule in the future.

Researchers intend to leave the project instructions in USB. However, that certainly won't work, given that digital technology is often not sustainable.

In addition, they also feel that leaving instructions on paper copies is not a good idea because the paper could not last for 500 years. It will definitely turn yellow and fall apart.


No strategy will be completely safe 500 years later. So, researchers are asked to copy the instructions every 25 years to remain relevant linguistically and technologically, hoping that this experiment will continue to exist and not be forgotten.
