Upcoming Satellite Mission May 'See' How Early Universe Cooled

As the early universe cooled

shortly after the Big Bang, bubbles formed in its hot plasma, triggering gravitational waves that could be detectable even today, a new study suggests.

In the new study

the scientists model how these gravitational waves could produce a signal that would be detectable by LISA using a technique known as holographic duality.

Holographic duality is

based on string theory and enables scientists to mathematically describe the behavior of particles in gravity and gravity-free environments.

Using this technique scientists

could analyze the events in the early universe. Their model took into account the temperature at which the transition was likely taking place

Scientists think as

the hot plasma cooled down, bubbles started to form in it as part of the so-called nucleation process
