Dtor pauhertz is director of astrophysics at nassau. He tells a story about what scientists think happened before that first light of the universe. We can't see with light that part of the universe, but there are telescopes that can detect things that are not light. In 20 15, scientists detected gravitational waves coming from two black holes colliding. And they cold potentially detect gravitational waves from right after the big bang,. So it'll be like flapping space. Anything within that space will warp. It's like looking at a fun house mirror, but we are in the mirror, ot to speak. This is still something that astronomers dream of being able to do some day
To look into deep space is to look back in time. With the upcoming launch of the James Webb Space Telescope, scientists hope to see “cosmic dawn,” a period long ago when the first starlight transformed the universe. But what happened before cosmic dawn? The Webb can’t tell us, though future telescopes could.
