Andromeda, which at 220,000 lightyears across is twice the size of the Milky Way, is approaching the our galaxy at around five million kilometres a year.
When the galaxies do meet, Earth could be flung into the centre of Andromeda, where its supermassive black hole would consume the planet.
Fabio Pacucci, an astrophysicist at Harvard University & Smithsonian Astrophysical Observatory, said during a Ted Talk: “Unlike their stellar cousins, supermassive black holes aren’t wandering through space.

What's inside a black hole? | Fox News
This image released Wednesday, April 10, 2019, by Event Horizon Telescope shows a black hole. Scientists revealed the first image ever made of a black hole after assembling data gathered by a network of radio telescopes around the world.

First, we need to clear up some definitions. There are many kinds of black holes: some big ones, some small ones, some with electric charges, some without, and some with rapid rotations and others more sedentary. For the purposes of our adventure in this particular tale, I'm going to stick to the simplest possible scenario: a giant black hole with no electric charge and no spin whatsoever.
Black hole shock: Trio of supermassive monsters collide to create mega black hole | Science |
Of the almost countless galaxies already recorded, NGC 6240 has appear almost unique due to its strange shape and unusual infrared brightness. This was believed to be the result of two galaxies colliding – until now.
Astronomers more than 30 years ago reported evidence of a double active nucleus, with a brace supermassive black holes sitting at NGC 6240’s centre.
Such a concentration of three supermassive black holes has so far never been discovered in the Universe

TESS watched a black hole tear apart a star | Space | EarthSky
TESS watched a black hole tear apart a star from start to finish, a cataclysmic phenomenon called a tidal disruption event.
When a star strays too close to a black hole, intense tides break it apart into a stream of gas. The tail of the stream escapes the system, while the rest of it swings back around, surrounding the black hole with a disk of debris. This video includes images of a tidal disruption event called ASASSN-19bt taken by NASA's Transiting Exoplanet Survey Satellite (TESS) and Swift missions, as well as an animation showing how the event unfolded.
Internet black hole could cost iiNet $10m | 7NEWS.com.au
One customer left without internet for more than three weeks while they waited for the National Broadband Network could end up costing iiNet $10 million.
The communications watchdog told iiNet on Tuesday to complete an internal audit into how the customer was left in the dark for so long.
The Australian Communications and Media Authority warned failure to comply could see the internet provider whopped with civil penalties of up to $10 million.
General election 2019: Conservatives face £70bn manifesto black hole after promising expensive
Tory sources said future investment plans would be funded by a £100bn pot of capital expenditure, only £22bn of which has so far been allocated to specific projects.
Mr Johnson has promised other policies - including a cut to National Insurance, greater provision of social care and a reduction in student debt - which would add to the annual budget for day-to-day spending. If the Tories are re-elected, Chancellor Sajid Javid is expected to set out the spending increases at future Budget announcements as well as detailing how they will be funded.
Supermassive black hole found spawning stars at 'furious rate' of 500 per year, NASA says | Daily
A supermassive black hole discovered by NASA has been spawning stars at a 'furious rate' and could help explain mysteries behind where the gaseous bodies come from.
Using observations from NASA's Chandra X-ray Observatory and the Hubble Space Telescope, MIT researchers have keyed in on on a distant galaxy cluster called the Phoenix Cluster, which they say contains a supermassive black hole with the ideal conditions for star creation.
Unlike other supermassive black holes found at the center of other galaxies, researchers say the one found inside the Phoenix Cluster is much weaker, allowing large clouds of gas inside the galaxy to cool and begin the process of forming a star.
