the universe is infinite or finite, but it is believed that the universe is expanding based on observational records. If the universe is already infinite, what does it mean for it to expand further?

The origin of our Universe remains one of the greatest enigmas of science, a question that seems to defy the limits of our physical understanding. For decades, cosmologists have struggled with the ...

The low carbon levels are particularly interesting, as previously discovered “pristine” or metal-poor stars generally displayed high carbon levels. Astronomers believed that relatively heavier ...

Is the universe really limited to just four dimensions — length, width, height, and time? For nearly a century, theoretical physicists have been exploring a mind-bending idea: that reality might ...

This composition means it is a likely candidate for one of the earliest stars in the universe, with astronomers previously theorising that such stars had long since exploded due to a lack of heavier ...
