It's difficult to know what you're asking here, but yes, he matter part is effectively only rest mass energy: the kinetic energy component of normal matter is, today, such a minuscule fraction of its energy density that it might as well be neglected.icarus2 said:In a WMAP
Matter(4.6) / Dark matter(23.3) / Dark Energy(72.1)
100= M_ord(4.6) + M_dark(23.3) + DE(72.1)
The M_ord is Mc^2 ?
Matter part is only rest mass energy?
M_ord ? mc^2 + gravitational potential energy
M_ord ? mc^2
A WMAP (Wilkinson Microwave Anisotropy Probe) is a satellite launched by NASA in 2001 to map and study the cosmic microwave background radiation, which is the leftover heat from the Big Bang.
WMAP collects data by scanning the entire sky in 5 different microwave frequencies. It uses a differential microwave radiometer to measure the temperature of the radiation coming from different parts of the sky.
The data collected by WMAP has helped scientists confirm that the universe is 13.8 billion years old, determine the composition of the universe, and provide evidence for the inflation theory of the early universe.
WMAP has provided the most detailed and accurate map of the cosmic microwave background radiation, which has allowed scientists to study the early universe and make important discoveries about its age, structure, and composition.
The successor to WMAP is the Planck satellite, launched by the European Space Agency in 2009. It is expected to provide even more precise data on the cosmic microwave background radiation and further advance our understanding of the universe.
