Bertacca added that this approach could mean the universe is twice as old as previously believed, suggesting that gravitational ripples may still shape cosmic behavior today.
A New Era in Cosmology
If confirmed by future observations, this gravitational-wave-based Big Bang model could transform cosmology and our understanding of how the universe began. The team emphasizes that ongoing measurements and space-based experiments will be crucial for testing the theory.
“As researchers compare our predictions with real data, we’ll gain a clearer view of the universe’s true origins,” Bertacca said. “These gravitational ripples interact and build complexity over time, leading to testable predictions that we can now analyze.”
