What does diaphragmatic attenuation artifact mean in your stress tests results?
Sometimes your diaphragm (breathing muscle) can cause what appears to be an area of ischemia (low-blood flow) in your heart. This is a "diaphragmatic attenuation artifact." It may be a true "fixed defect" or it may not be anything at all. A "fixed defect" means that you have a complete blockage, or an almost complete blockage to a terminal segment of the artery going to your heart. Exercise is supposed to dilate your arteries. So a fixed defect means that there was no ability to dilate that segment and to deliver further blood to that area. It can mean you had a previous infarction (heart attack).
Does attenuation happen when EM wave travels in space?
There is no attenuation due to absorption, but attenuation will occur due to divergence (spreading out) of the wave.

how old should a artifact be to be a artifact?
An artifact, by definition, is an object made by a human being, typically one of historical or cultural interest. For an object to be considered an artifact, it doesn't necessarily have to reach a specific age, but it is generally expected to be from a past era, significant for its cultural or historical context. Typically, artifacts are often ancient and are associated with civilizations or individuals from long ago. However, items from more recent history can also be considered artifacts if they have significant cultural or historical relevance. The essence of an artifact lies in its ability to offer insights into the past and its civilizations, cultures, or individuals, rather than its age per se. Whether it's a tool from ancient civilizations or a document from a few decades ago, its historical or cultural significance determines its status as an artifact.
