Scientists have created a virtual reality (VR) simulation of Sagittarius A* -- the black hole at the centre of our galaxy -- that allows viewers to better visualise the phenomenon.
Scientists at Radboud University in The Netherlands and Goethe University in Germany used recent astrophysical models of Sagittarius A* to create a series of images that were then put together to create a 360 degree virtual reality simulation of the black hole, that can be viewed on widely available VR consoles.
"Our virtual reality simulation creates one of the most realistic views of the direct surroundings of the black hole and will help us to learn more about how black holes behave," said Jordy Davelaar, corresponding author of the study published in the journal Computational Astrophysics and Cosmology. "Travelling to a black hole in our lifetime is impossible, so immersive visualisations like this can help us understand more about these systems from where we are," said Davelaar.
Researchers also suggest that the virtual reality simulation could help encourage the general public, including children, to take an interest in astrophysics.
"The visualisations that we produced have a great potential for outreach. We used them to introduce children to the phenomenon of black holes, and they really learned something from it," said Davelaar.
"This suggests that immersive virtual reality visualisations are a great tool to show our work to a broader audience, even when it involves very complicated systems like black holes," he said.
"We all have a picture in our head of how black holes supposedly look, but science has progressed and we can now make much more accurate renderings - and these black holes look quite different from what we are used to. These new visualisations are just the start, more to come in the future," said Heino Falcke, a professor at Radboud University.
