This project aims to test the variation of fundamental physical constants across our galaxy by using twins of our Sun, a new probe that unlocks a 1000-fold sensitivity gain. The standard model of nature's laws cannot explain fundamental constants, like electromagnetism's strength, alpha. By discovering distant solar twins, the project intends to probe alpha in regions of very different Dark Matter density, opening an unexplored discovery space. Expected outcomes include the most precise astronomical measurement of a fundamental constant, and the first test of variations in alpha across our Galaxy's Dark Matter field.

该项目旨在通过使用太阳的孪生子来测试整个银河系基本物理常数的变化，这是一种新的探测器，可以获得1000倍的灵敏度增益。自然定律的标准模型无法解释基本常数，如电磁强度α。通过发现遥远的太阳双胞胎，该项目打算在暗物质密度非常不同的区域探测α，打开一个未探索的发现空间。预期成果包括对基本常数进行最精确的天文测量，以及对银河系暗物质场α变化的首次测试。
