The presence of Primordial Gravitational Waves in the Cosmic Microwave Background
Abstract
The General Relativity affirms that any field is a source of gravitational field, thus one should affirm that the energy of Cosmic Microwave Background (CMB) generated primordial gravitational waves. The present article shows that a gravitational wave with dimensionless amplitude 10-5 and large wave length 10 megaparsecs shifts temperature of CMB radiation about of a part in 105.
