00:00this is what is called the Radcliffe wave and it's been a mystery to scientists since it was
00:08discovered back in 2020 the whole thing stretches an enormous 9,000 light years but it resides in
00:14the Milky Way just 500 light years from our solar system so what is it well it's a convergence of
00:19star-forming gas which is in and of itself pretty remarkable but more recently they realized that
00:24it actually looks more like this a moving structure oscillating like a proper wave this
00:29all comes after recent improvements to 3d maps of our galaxy and they might actually have an idea
00:34of why it is moving as well the researchers say that the explanation is pretty simple and that
00:39it's being pulled on by gravitational interactions with other matter around it a far cry from the
00:43initial possibility of dark matter causing the structure to undulate in such a way it's even
00:48possible the physicists say that the stars that went supernova before the Milky Way took their
00:52place may have even formed within the Radcliffe wave now the question remains what caused this
00:57star-forming wave to appear in the first place
