Abstract

Scientists have known for a while that the universe is expanding, and it’s doing so faster and faster. This strange phenomenon is caused by something we call dark energy. To understand this better, we need to think about a special number called the Cosmological Constant. It helps us describe how things move in space. 

In our research, we aimed to uncover how dark energy causes objects like stars and galaxies to interact. As an example, we’ve been studying our neighbor galaxy – Andromeda. By looking at how it moves and at its mass, we can see how dark energy affects it.
