Which space probe S was were used to map the background microwave radiation throughout the universe?

Microwave Anisotropy Probe

What does cosmic microwave background radiation say about our universe?

The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background”, or CMB.

What is cosmic microwave background radiation a form of?

The cosmic microwave background (CMB) is thought to be leftover radiation from the Big Bang, or the time when the universe began. As the theory goes, when the universe was born it underwent a rapid inflation and expansion. This means its radiation is most visible in the microwave part of the electromagnetic spectrum.

What is the best description of cosmic microwave background radiation?

The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity.

What are the three possible outcomes for the universe?

The three possible outcomes include: an open universe, in which the expansion will never stop; a closed universe, in which the expansion will stop and turn into a contraction; and a flat universe, in which the expansion will slow to a halt in time—but it will never contract.

What could be at the end of the universe?

The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

What is the fate of the universe will it continue to expand?

As long as the amount of stuff doesn’t go over a critical threshold, the universe will continue to expand forever, and eventually suffer heat death, freezing out. But if there’s too much stuff, the expansion of the universe will slow down and stop. Then the universe will begin to contract.

What is most of the universe made of?

Composition. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the universe) and antimatter.

Can the universe run out of energy?

If that’s how dark energy works, and it’s indistinguishable from a cosmological constant, it teaches us that the Universe will never run out of energy, as there will always be a finite amount of energy inherent to the fabric of space itself. But, as an important counterpoint, it isn’t useful, extractable energy.
