Echoes of the cosmos

"Echoes of the Cosmos." This story delves into the implications of advanced technology that can decode electromagnetic signals from the past.

Here's a summary of the story's key aspects:

* The Universal Electromagnetic Decoder (UED): In 2050, the Global Signal Institute (GSI), led by Dr. Elena Navarro, invents the UED, a device capable of interpreting various electromagnetic waves in real time.

* The Temporal Signal Array (TSA): By 2075, Dr. Amir Khan enhances this technology, creating the TSA. This array allows for the reconstruction of past electromagnetic signals, including private communications and even bioelectric traces of human thoughts, offering a means to expose "powers in the shadows."

* Uncovering Hidden Forces: The TSA reveals hidden forces manipulating historical events and uncovers a mysterious figure known as "The Architect." It also decodes signals from a vanished civilization and Earth's deep past.

* Ethical Dilemmas and Restrictions: The misuse of the TSA leads to significant ethical dilemmas and widespread global paranoia, eventually resulting in restrictions on its use.
