The final, formatted version of the article will be published soon. The Euclidean Model of Space and Time (EMST) was created as an alternative to the Special Theory of Relativity (STR) and the ...

This is an example of time dilation, a consequence of the idea that time and space are not absolute - meaning all observers do not always measure these quantities as the same. In everyday life we use ...

There’s endless debate among cosmologists about what really makes up the emptiness of outer space, though many believe that mysterious stuff that we now call dark matter and dark energy represent a ...

Surging demand for energy to power artificial intelligence (AI) data centers is reaching new heights as companies are pursuing plans to station data centers in space. Billionaire entrepreneurs Elon ...

Shortly after space week in October, investment firm JP Morgan announced a $10 billion investment plan targeting industries critical for United States national security. In addition to things like ...

The space station industry is starting to take off. For decades, if you wanted to send an astronaut or experiment into orbit, the International Space Station (ISS) was the only option. But now, as ...
