According to our current understanding of physics, as described by Einstein's theory of relativity, spacetime is a four-dimensional construct, consisting of three spatial dimensions and one time dimension. This framework has been extensively tested and has successfully predicted and explained a wide range of phenomena.
While there have been speculative ideas and thought experiments in theoretical physics that explore concepts like extra dimensions or alternative geometries of spacetime, they are mostly theoretical constructs and have not been supported by experimental evidence thus far.
It's important to be cautious when encountering sensationalized or exaggerated claims in the media, especially in the realm of scientific discoveries. It is always a good practice to seek reliable sources and scientific publications to evaluate the credibility and accuracy of any scientific claim.
