Atomic Clocks Experiment Reveals Time Dilation at The Smallest Scale Ever

In his theory of general relativity, Einstein predicted something called¬†time dilation: the notion that two clocks under two different gravitational pulls will always tick at different speeds. ¬† The effect has been observed in many experiments since, but now scientists have recorded it at the smallest scale seen so far. The result was achieved using … Read more

Redshift and blueshift: What do they mean?

Redshift and blueshift describe the change in the frequency of a light wave depending on whether an object is moving towards or away from us. When an object is moving away from us, the light from the object is known as redshift, and when an object is moving towards us, the light from the object … Read more
