ajanlevitys
Ajanlevitys is a Finnish term that broadly translates to "time spreading" or "time dilation" in English. It refers to a phenomenon where the passage of time is perceived differently by observers in different frames of reference. This concept is most famously described in Albert Einstein's theories of relativity, particularly special relativity and general relativity.
In special relativity, ajanlevitys occurs due to relative velocity. An observer moving at a significant fraction
General relativity introduces another form of ajanlevitys caused by gravity. Time passes slower in stronger gravitational
While ajanlevitys is a core concept in modern physics, it is often counterintuitive to everyday human experience,
