The authors of a new study believe that ripples in space, known as gravitational waves, will reveal
Using equations that define movementselectromagnetic waves through the plasma inside fusion reactors, scientists have created a theoretical model of the interaction of gravitational waves and matter. This, in turn, will help them “look into the past” and better understand what happened at the dawn of the Universe.
Moments after the Big BangThe universe was saturated with hot, super-dense primordial plasma, which sent powerful gravitational waves into space. They spread throughout the entire space and their influence is still felt today. The mutual influence that matter and gravitational waves had on each other after the Big Bang left observable traces, scientists say. By working backwards, they wanted to get a more accurate picture of the early Universe.
To calculate how the primary plasma affectedto ancient gravitational waves, the authors of the new study carefully analyzed the equations of Einstein's theory of relativity, which describes how the geometry of space changes as matter moves through it. Under certain simplifying assumptions about the physical properties of matter, they calculated how gravitational waves and matter influence each other. Physicists based part of the equations on the propagation of electromagnetic waves in a plasma. This happens not only in space, but also here on Earth, in nuclear reactors.
Although scientists have taken an important step toward calculatingThere is still a lot of work to be done on the measurable effects that gravitational waves and the primordial plasma may have had on each other. Physicists need to do more precise and detailed calculations to get a clearer picture of what these ancient gravitational waves would look like today.
