The Big Bang produced a hot, dense, nearly homogeneous universe. As the universe expanded and cooled, particles, then nuclei, and finally atoms formed. At a redshift of about 1100, equal to about 400,000 years after the Big Bang, when the primordial plasma filling the universe cooled enough for protons and electrons to combine into neutral hydrogen atoms, the universe became optically thin by which photons from this early era no longer interacted with matter. We detect these photons today as the cosmic microwave background (CMB). The CMB shows that the universe was still smooth and uniform.
After the protons and electrons combined to produce the first hydrogen atoms, the universe contained a nearly uniform, almost completely neutral, intergalactic medium (IGM) for which the most amount of matter component was hydrogen gas. With no glowing sources present, these are known as the Dark Ages. Theoretical models predict that, over the next few hundred million years, gravity slowly condensed the gas into denser and denser regions, in which the first stars eventually appeared, marking Cosmic Dawn.
As more stars formed, and the first galaxies formed, they flooded the universe with ultraviolet photons capable of ionize hydrogen gas. A few hundred million years after Cosmic Dawn, the first stars produced enough ultraviolet photons to re-ionize essentially all the universe's hydrogen atoms. This is called the Reionization era which is the hallmark event of this early generation of galaxies.
The beginning of structural complexity in the universe caused a remarkable transformation, but one that we have not yet looked into. By going even farther back than what the Hubble telescope can see, the truly first structures in the universe can be studied. Theoretical models suggest that present measurements are beginning to find the last part of Reionization, but the first stars and galaxies, in the Dark Ages and the Cosmic Dawn, currently lie above our understanding.
DARE will make the first measurements of the birth of the first stars and black holes and will measure the properties of the invisible stellar objects. Such observations are important for placing current measurements in a proper context, and to understand how the first galaxies grew from earlier generations of structures.
DARE's mission is to measure the shape of the redshifted 21-cm signal over a radio bandpass of 40–120 MHz, observing the redshift range 11–35, which correlate to 80–420 million years after the Big Bang. DARE orbits the Moon for 3 years and takes data above the lunar farside which is the only location in the inner Solar System proven to have no human-generated radio frequency problems.
The science instrument is set to a RF quiet spacecraft bus and is made of a three-element radiometer, including electrically-short, tapered, biconical dipole antennas, a receiver, and a digital spectrometer. The smooth frequency response of the antennas and different measurements used for DARE are important in removing the intense cosmic foregrounds so that the weak cosmic 21-cm signal can be detected.
Besides DARE, are other similar projects are proposed to also study this area such as the Precision Array for Probing the Epoch of Reionization (PAPER), Low Frequency Array (LOFAR), Murchison Widefield Array (MWA), Giant Metrewave Radio Telescope (GMRT), and the Large Aperture Experiment to Detect the Dark Ages (LEDA).

Pornography addiction
Pornography addiction means someone is addicted to viewing porn. This addiction can be compulsive. Porn viewing is usually viewed as a problem if it interferes with someone's financial or social life. Some people with porn addiction say they suffer from social isolation or depression. There are also some celebrities who have porn addiction. Some celebrities with porn addiction have said that the porn addiction affected their marriage. For some celebrities, porn addiction was the main cause of their divorce.
Some analysts say that porn addiction is caused by the difficult of dating for example men outnumbering female on dating sites and fake female bot dating profiles. Some analysts say porn addiction in men is caused by the 80/20 rule wherein women are only attracted o the top 20% of men. The 80/20 rule was discovered in many dating site statistics.
