Astronomers have a very successful model of the Universe – the so-called Lambda CDM Universe,
containing ordinary matter, radiation, dark matter and dark energy.
It fits almost everything very nicely, but there
is one fly in the ointment: what we see from the early Universe predicts
how fast the Universe should be expanding today (the Hubble Constant),
but recent measurements indicate that its actually expanding a bit faster
than that, by nearly 10 percent. Is it a mistake, or does it tell us that
we dont understand the Universe after all, and some new physics must come
into play?
