Dark Matter findings suggest Einstein's Theory of relativity "May Be Wrong"
Dark matter it's the most mysterious substance in the universe little is known
about it scientists are pretty sure it exists but still don't know what it is
now they have created the largest ever distribution map of dark matter in the
universe as our science correspondent Caleb ghosh reports look up at the skies
and you see stars but this telescope in the deserts of chile is able to see the
universe as it really is filled with a mysterious substance called dark matter
it can't be seen but this instrument can detect dark matter by the way it
distorts starlight this is a map of matter in the universe and that's allowed
astronomers to produce this map of how it's spread across the expanse of space
it's an element of you know unveiling mystery something you you couldn't see
before and suddenly it's there and you think wow so what is dark matter and
where is it in space well let's start off with our own sun it's one of a hundred
billion stars that make up our galaxy the milky way which in turn is one of
countless others throughout the universe dark matter permeates space with
galaxies like tiny gems on a tangled cosmic web the bright areas are where dark
matter is most concentrated and it's here that galaxies form but the map is not
what astronomers expected the matter should be slightly more clumped together
instead it's smoother than predicted by einstein's theory of general relativity
which helps determine how the matter should have spread out after the big bang
if the structures in this map are smoother than we expect them to be which is
what the results seem to hint at it means that einstein's theory is wrong so you
might think that that's a bad thing that maybe or no physics is broken but for
physicists is extremely exciting because it means that we can find out something
new about the way the universe really is building on the work of einstein carlos
frank was among a group of scientists that developed the current model of
cosmology hearing now that there may be something not quite right with the
theory well it's very disconcerting it's very alarming and in a way frightening
to see that maybe my whole life's work might crumble in front of me but at the
same time it is immensely exciting astronomers believe that we are at the start
of a new revolution in cosmology that will give us a fuller understanding of how
the universe began and how it will evolve palab gauche
