In the center of our galaxy, the Milky Way,

slowly eating the galaxy isn't terrifying enough,

This monstrosity creeping through the Milky Way

It's an extremely dense and very magnetic

Let me refresh your knowledge of magnetars.

at least eight times more massive than our Sun,

Most of these remnants become neutron stars.

Some neutron stars have such strong magnetic fields

that they emit electromagnetic radiation from their poles.

and you can observe them with a telescope

such an extremely powerful magnetic field.

They become the strongest magnets in the Universe.

Or would a black hole gobble up a magnetar?

Although magnetars are incredibly powerful,

they would lose the battle with a black hole.

Depending on the trajectory of the magnetar,

As the magnetar was being torn apart by the black hole,

it would be sending gravitational waves throughout the Universe,

Once the black hole consumed the magnetar,

its mass would increase and expand its event horizon.

Eventually, after quadrillions of years of star consumption,

the black hole could gobble up the Milky Way, all of it.

disrupts this feast some 4.5 billion years from now.
