Query: Dark torsion as the cosmic speed-up   It is shown that the recently detected acceleration of the universe can be
understood by considering a modification of the teleparallel equivalent of
General Relativity (TEGR), with no need of dark energy. The solution also
exhibits phases dominated by matter and radiation as expected in the standard
cosmological evolution. We perform a joint analysis with measurements of the
most recent type Ia supernovae (SNe Ia), Baryon Acoustic Oscillation (BAO) peak
and estimates of the CMB shift parameter data to constraint the only new
parameter this theory has.
