In his talk at the Foresight Space Workshop ’23, theoretical physicist and computer scientist Adam Brown discusses the cosmological constant and its implications for space exploration and technology. He explains that the discovery of the cosmological constant, which indicates the accelerating expansion of the universe, poses challenges for accessing distant galaxies and utilizing their resources. However, Brown suggests that the constant might be manipulatable, offering the possibility of extracting energy from it to prevent the heat death of the universe. Brown draws an analogy to manipulating an electric field to extract energy, highlighting the potential for accessing unlimited free energy if the cosmological constant can be controlled. He notes that the detectability and impact of the cosmological constant depend on its distance and location, and the bleeding off of the constant’s energy might be observable rather than the constant itself. However, manipulating the cosmological constant could have consequences, such as affecting the laws of physics, including gravity, electromagnetism, and the strong force. Adapting to new laws of physics would require transforming ourselves into a medium suitable for these changes. Brown emphasizes the important role of the cosmological constant’s power density in understanding the dynamics of the universe and raises the question of whether it is possible to overcome the limitations imposed by the constant’s acceleration of the universe’s expansion.
