NASA scientists confirm the accuracy of scientific forecasts regarding the birth of the universe and help unravel many mysteries surrounding its ongoing expansion.
Data collected from the WMAP satellite has enabled NASA scientists to create a cosmic microwave background map, providing evidence that supports the predictions and mathematical models of the Big Bang, which is believed to have formed the universe approximately 13.7 billion years ago.
The Big Bang theory asserts that prior to the explosion, all matter and energy in the current universe were compressed into an extremely small space, with each dimension measuring only one ten-trillionth of a meter. This is the smallest space that can exist according to the laws of physics and cannot be compressed further.
NASA scientists also affirm that within the first trillionth of a second, the Big Bang released an energy field filled with particles that possess negative gravity, known as inflatons. These particles repelled each other in all directions and decayed into fundamental particles and energy in the form of quantum light.
The universe continued to expand for 400,000 years afterward, cooling down enough for electrons and protons to combine into hydrogen atoms. As a result, quantum light particles were no longer colliding with electrons and became primitive light sources that could travel across the universe unobstructed.
Current satellites equipped with modern instruments have captured this primitive light, which serves as further evidence of the existence of the Big Bang that formed the universe.
From the data obtained from space, NASA scientists also confirm the mathematical models regarding the existence of cold dark matter and dark energy, which exert a reverse gravitational force.
Mathematical models related to the cosmological constant have identified this dark energy as a characteristic of the universe, remaining constant at every point in space and time. This mysterious source of energy explains the continuous expansion of the universe both during and after the Big Bang.
Scientists from NASA’s Solar System Exploration program have also confirmed the presence of life components on Saturn’s moon Enceladus.
Dr. Bob Pappalardo, who has been studying data from NASA’s Cassini spacecraft exploring Saturn for the past two years, stated that while focusing on finding signs of life on Enceladus, NASA scientists discovered life components on this moon through data transmitted back to Earth by the Cassini spacecraft when it flew through space at an altitude of about 160 km from Enceladus’ surface.
The newly discovered data confirms that Enceladus has an atmosphere containing life components such as organic molecules, water vapor, and heat. The gases forming the atmosphere are emitted from fractures on Enceladus’ surface. Most of this atmosphere consists of water vapor, suggesting that liquid water may exist beneath the icy surface of this moon.
