Black hole 'may be spinning space itself'

Astronomers have detected a black hole that is spinning so rapidly that it may be causing space itself to rotate.
Observations of the black hole, which is situated in the binary star system 4U 1630-47, indicate that it has a mass ten times that of the Sun and is rotating at 90 percent of the speed of light.

It was first detected back in 2016 by India's AstroSat and NASA's Chandra X-Ray Observatory.
It is one of only five black holes to have accurately measured high spin rates.

"The scientific measurement of the spin rate of the black hole, an extremely exotic but the simplest object of the universe, comes out to be close to the maximum possible value," said principal investigator Sudip Bhattacharyya from the Tata Institute of Fundamental Research in India.

"This is generally very important to probe some extreme aspects of the universe, and the fundamental physics (for example, the theory of gravitation) related to them."

Photons travel in straight lines but the space they are traveling through can be curved by gravity, that's why you get black holes and gravitational lensing. They're still traveling at c, in the case of black holes they just can't get out.

How could a massless photon be deflected by gravity ?

Deflected? No, the space is curved so extreme once it enters the black hole it can't escape. The event horizon is where the escape velocity is the speed of light, past that light can't escape.

Space is curved due to the gravitational field of the black hole.  The photon travels through this curved space.  Ergo the photon is effected by gravity.  Ergo the photon has mass ?

"rotating at 90 percent of the speed of light" I don't trust physicists who talk such utter nonsense.

Are you sure it hasn't?

And why is that nonsense.  Do you know something the scientists don't?

So basically the theory behind Star Trek's Warp Drive, folding Space in on itself to make travelling faster than light possible.

Rotation is Rotation is another physical quantity  then velocity.

I don't trust non-physicists who talk such utter nonsense.
