How the Universe Works?

Understanding the universe’s birth and its ultimate fate are essential first steps to unveiling the mechanisms of how it works. So, we require knowledge of its history, which started with the Big Bang. According to NASA, they investigated with the Cosmic Microwave Background Explorer (COBE). The Wilkinson Microwave Anisotropy Probe (WMAP) measured the radiation from the universe when it was only 300,000 years old. It confirmed the theoretical models of its early evolution. With its improved sensitivity and resolution, ESA’s Planck observatory probed the long-wavelength sky to new depths during its 2-year survey, providing stringent new constraints on the physics of the first few moments of the universe.
