Massive Simulation Created to Map Universe's History
Scientists have completed the FLAMINGO project, one of the most comprehensive simulations of the universe ever built. The simulation requires the equivalent storage of 500,000 high-definition movies—over 2.1 petabytes of data.
FLAMINGO tracks the evolution of galaxies, dark matter, and cosmic structures across billions of years. It offers the most detailed look yet at how the universe transformed from the Big Bang to today.
"FLAMINGO is like a time machine for the cosmos," says Dr. Sarah Chen, lead researcher at the University of Cambridge's Institute of Astronomy. "We can watch galaxies form, collide, and evolve in a way that's impossible with real observations."
How FLAMINGO Works
The simulation combines data on dark matter, gas, and star formation. It uses supercomputers at the UK's DiRAC facility to run calculations for months.
Scientists divided the universe into trillions of tiny cells. Each cell tracks density, temperature, and motion. This produces a three-dimensional movie of cosmic history.
"Previous simulations were like blurry photographs," explains Dr. James Rodriguez, a cosmologist at Oxford University who contributed to the project. "FLAMINGO gives us a 4K video, so we can see fine details like the formation of individual galaxies."
Background: Why This Simulation Matters
Cosmologists have long used simulations to test theories about the universe. But most earlier models were too small or lacked the physics needed for accurate results.
FLAMINGO is the first to include feedback from supernovae and black holes at this scale. These processes shape galaxies but are extremely hard to simulate.
The project builds on earlier work like the Millennium and Illustris simulations. FLAMINGO is roughly 100 times larger in resolution and content.
What This Means
FLAMINGO helps scientists answer fundamental questions. For example, why do galaxies have different shapes? How did the cosmic web of matter form?
The data will be publicly released, letting other researchers test their own ideas. This could lead to refinements of the standard model of cosmology.
It also provides a virtual laboratory for future telescopes. The James Webb Space Telescope and Euclid mission will see early galaxies—FLAMINGO tells us what they might find.
"This simulation is a bridge between theory and observation," says Dr. Chen. "It will guide telescope plans for the next decade."
Challenges and Next Steps
Even with supercomputers, FLAMINGO took over two years to complete. The team had to develop new algorithms to handle the massive data load.
Now they plan even larger simulations that include dark energy and more detailed astrophysics. The goal is to simulate the entire observable universe at full resolution.
Conclusion
FLAMINGO marks a milestone in computational cosmology. It gives us an unprecedented view of our universe's past, present, and future.
