Why space doesn't suck all the air from earth even though its vacuum?

Air on Earth does not escape to the vacuum of space because Earth has a gravitational force that keeps the air molecules bound to it. Gravity is the force that attracts objects with mass to one another, and it is what keeps the air molecules from escaping into space.

The Earth's gravitational force is strong enough to hold onto its atmosphere, which is made up of gases such as nitrogen, oxygen, and carbon dioxide. These gases have mass and are attracted to the Earth's surface, which means they stay close to the planet rather than drifting off into space.

Additionally, the Earth's atmosphere is constantly replenished by various processes such as volcanic activity, plant respiration, and the evaporation of water from the oceans. This ensures that the atmosphere remains relatively stable and that the air doesn't escape into the vacuum of space.

Finally, it is important to note that some molecules in the Earth's atmosphere can, in fact, escape into space, but this is a slow and continuous process. This loss of atmosphere is balanced by the constant replenishment mentioned above, which keeps the overall atmospheric pressure and composition relatively stable over time.

The truth behing the hidden chamber's revealed Inside the Great Pyramind of Giza

Even at 4,500 years old, the Great Pyramid of Giza is still revealing new secrets. On Thursday, Egyptian officials announced the discovery of a hidden corridor above the pyramid's entrance. Measuring 30 feet long, the passage could serve as a jumping-off point for additional research into the mysterious inner chambers.

According to a new study published in the journal Nature Communications, the pyramid has been undergoing noninvasive scans since 2015. Through an international partnership known as ScanPyramids, researchers from around the world have been using cosmic-ray imaging and infrared thermography to map out what lies behind the sand-beaten stones of the exterior.

These scans have revealed several voids, including the 30-foot passage, which lies just behind a chevron-shaped configuration of stones not far from where today's tourists enter the pyramid. A video released by ScanPyramids offers a glimpse into the mapping process and shows where this newly discovered corridor lies.

Dinosaur with the longest neck ever to exist on Earth found.

Think giraffes have long necks? Paleontologists say a dinosaur that roamed northwest China some 162 million years ago had a neck eight times as long, making it the "longest-known neck in the animal kingdom," per IFL Science.

Partial remains of the dinosaur, Mamenchisaurus sinocanadorum, were discovered in the Xinjiang Uyghur Autonomous Region in 1987. More than three decades later, researchers assessed the dinosaur's size and scale in comparing the handful of fossilized bones, including three vertebrae, with bones from complete skeletons of related dinosaurs, per CNN. According to their study published Wednesday in the Journal of Systematic Palaeontology, this sauropod had a 50-foot-long neck, about 10 feet longer than a typical bus.

Miditerranean diet can cut heart disease risk in women by 24 percent.

A Mediterranean diet could lower the risk of heart disease in women by 24 percent, new research says.

It's the first such analysis of the possible link between a Mediterranean-type diet and cardiovascular disease that focuses on women, the authors say.

Heart disease is the leading cause of death globally, according to the World Health Organization, and in the United States, it is the No. 1 killer of women, the Centers for Disease Control and Prevention says.

Moez Ullah Khan, a student at the University of Oklahoma creates a website for students.

Moez Ullah Khan is a student at the University of Oklahoma. He is majoring in Mechanical Engineering with a minor in Computer Science. He recently created a website called "Discuss It" using HTML, CSS, and Java Script.

The purpose of this website is to provide a platform where people can share their original ideas, theories about something. It could be a description of an invention, new theory or theorem they came up with, or an explanation of a mystery. The possibilities are infinite. if you want to learn more about his work, then follow him on his Linkedln.
