What specific phenomenon does SPHEREx aim to measure regarding the earliest moments of the universe?
Answer
The physics of inflation that occurred less than a trillionth of a second after the beginning
Cosmic inflation describes a period of rapid, exponential expansion that took place an infinitesimal fraction of a second after the universe began. By mapping the distribution of hundreds of millions of galaxies across the entire sky, scientists can identify large-scale patterns in how matter is clustered. These patterns serve as evidence to distinguish between different theoretical models of how the early universe initiated its expansion.
