Does a fifth dimension exist? Despite dark matter making up the majority of the universe's mass, humanity has yet to detect it. A new study suggests that the reason may lie not in technical limitations, but in the very structure of space itself. This was reported by RBC-Ukraine, citing a scientific study published in the professional journal Physical Review D. A team of astrophysicists led by Yu-Dai Tsai hypothesized that dark matter and hypothe…
Dark matter’s secret force does the opposite of what scientists expected
Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected. An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands. That weakens its gravitational impact and usually slows the growth of cosmic structure rather than accelerating it.
