What If Dark Energy Doesn’t Exist?

The video explores the mysteries of dark matter and dark energy, highlighting a new study that suggests dark matter could explain the universe's expansion without dark energy. It introduces a hypothesis where dark matter exerts a repulsive force, similar to magnetic repulsion, potentially explaining the universe's accelerating expansion. The video also covers the discovery of new auroras on Jupiter by NASA's Juno spacecraft, which provides insights into the interactions between Jupiter's magnetic field and the solar wind.
