The conversation between human and AI assistant.
How reasonable is it for us to extrapolate what is out of the observable universe? What are some current theories?
How do scientists try to gather data about what's beyond the observable universe?
One way is through gravitational lensing, which occurs when the gravity of a massive object, such as a galaxy, bends light from more distant objects behind it. By studying how the light is bent, scientists can infer the presence and location of massive objects that are too distant to observe directly.
