Physicists Create Visualisation of The 2 Billion Years After Big Bang
What happened after the Big Bang? A team of physicists, harnessing the James Webb and Nancy Grace Roman space telescopes, are working to visualize the answer to that question using a novel computer 3D simulation called Lumina.

As space telescopes enable humanity to look further and further back in time, a new study by Harvard and Smithsonian Center for Astrophysics has introduced Lumina, which creates an unprecedented look at how the universe may have formed. The simulation harkens back to the nascent universe, from the moments that followed the Big Bang through the next 2 billion years of cosmic evolution.
“The early universe has become an exciting new frontier in astrophysics,” said lead researcher Oliver Zier, crediting the James Webb space telescope (JWST). “To understand what we are seeing with this telescope, we need to translate our theories into detailed predictions. After several years of work, with plenty of ups and downs, it is incredibly rewarding to see the simulation results and watch our predictions come to life in video.”
