The German Nazi time machine Cronos, known to the world by British journalist Nick Cook in 1999.
Two types of secret projects were called Raterntrager and Cronos.
This time machine was a project that could bend four-dimensional space around the machine and therefore bend time.
After the end of World War II, the Kronos time machine was brought to the United States with Nazi scientists.
The exact existence of the object remains a mystery, but it is said to be on a secret mission in the United States.
