This uniform and isotropic radiation can only be explained as photons that could FINALLY travel through our Universe, about 370,000 years after the Big Bang. Prior to that, the density of nucleons and electrons was so high that no photon could travel for very long before blasting into some of these particles that were trying to form an atom. Eventually the density became low enough that photons could avoid these pairs. At this point, photons began to travel through our Universe, and atoms began to form.
The spectrum and isotrophy of the CMBR is explained PERFECTLY by the Big Bang Theory. No other hypothesis can explain it in any other way beyond, "It's just there and I have no explanation WHY it should be."

What is background microwave?
microwave background radiation is a thermal radiation left from the early stage of universe when it was much small and much hotter and filled with uniformly distributed opaque fog of hydrogen plasma
Cosmic microwave background radiation found uniformly spread throughout the universe is supposed to be what?
Cosmic Microwave Background Radiation is electromagnetic radiation left over from the events of the Big Bang. This radiation causes a very slight increase in the universe's temperature; the coldest areas of the universe will be only about 2 degrees kelvin (2 degrees above absolute zero). It is not spread in a perfectly uniform pattern, though the differences in density are very slight.
What did scientists predict the big bang should have left behind?
A thermal radiation permeating the Universe almost uniformly, which is not associated with any massive objects near it. It is referred to as Cosmic background radiation.
Who was the first person the see evidence of the Big Bang Theory?
Arno Penzias and Robert Wilson, two radio astronomers, accidentally discovered evidence of the Big Bang Theory in 1965. They detected a faint background radiation uniformly spread throughout the universe, known as the cosmic microwave background radiation. This discovery provided strong evidence for the Big Bang Theory and was later awarded the Nobel Prize in Physics.
How does the CMBR serve as evidence for the Big Bang theory?
Cosmic microwave background radiation is a thermal radiation which fills our universe uniformly. Before the formation of stars and planets when universe was young, it was much smaller and hotter and filled with uniform glow of hydrogen plasma but As the universe expand it grew Cooler and when universe is cool enough electrons and protons form neutral atom then these atom No longer absorb thermal radiation and universe become transparent instead of being opaque fog and thus this theory explain the evidences of big bang that it's really a phenomena that creates everything that you see

What is homogenious and heterogenious matter?
Homogeneous mixture -uniformly distributed throughout the composition heterogeneous mixture -not uniformly distributed throughout the composition

What is a homogeneous mixture of two or more substances uniformly spread throughout as a single phase?
suspension
How is heterogeneous and homogeneous micture relaed?
A Heterogeneous mixture is one where the mixture is not uniformly equal, meaning that its not the same throughout.A Homogeneous mixture is uniformly equal. The concentration of the mixture is the same throughout.
A large temperature lapse rate would occur in a layer with?
a) uniformly cold temperatures throughout b) cold air above, warm air below c) warm air above, cold air below d) uniformly warm temperatures throughout
What is a mixture that looks the same throughout because it's components are uniformly mixed together?
This is called a homogenous mixture
Difference between isotropic antenna and omnidirectional antenna?
The isotropicantenna by definition has a radiation pattern that is a perfect sphere. The omni driectional antenna is characterized by a radiation pattern resembling a doughnut.
What is the difference between homogeneous and heterogeneous?
A homogeneous mixture is one in which all components are uniformly distributed throughout the mixture. In a heterogeneous mixture the components are not evenly distributed throughout the mixture.
