Why in News
The Ram Janmabhoomi Teerth Kshetra Trust has denied reports about placing of a time capsule under the ground at Ram Temple construction site in Ayodhya.
- The Time Capsule, also known as Kaal Patra, was supposed to contain the history of Ayodhya and Rama Janma Bhoomi Movement.
Key Points
- Time Capsule is a container of any size or shape, which accommodates documents, photos and artefacts typical of the current era and is buried underground, for future generations to unearth.
- To ensure that the capsules do not decay they are built using special engineering techniques like steel or aluminium encasing, vacuuming, use of acid-free paper, etc.
- The time capsules mostly have a scheduled time for reopening, and are supposed to be buried again after opening, with people of the future adding their own contributions to the time capsule.
- The International Time Capsule Society (ITCS), based in the USA and formed in 1990, is now defunct but continues estimating the number of time capsules in the world.
- As per its database, there are 10,000-15,000 times capsules worldwide.

Significance
- Time Capsules are intended as a method of communication with future people.
- They are also supposed to help future archaeologists, anthropologists, or historians in knowing about the past human civilisation.
Criticism
- Most intentional time capsules are filled with a lopsided view of history. They are often politically motivated and glorify the people who planted them.
- They can not be regarded as facts and are not very reliable. The information in time capsules has to be verified with other sources of information.
- Many time capsules which have been unearthed were filled with junk telling little about the people of the time.
