Getting sick in space
Astronauts can experience various health issues in space, including space motion sickness, which is somewhat similar to motion sickness on Earth. Here's why astronauts can get sick in space:
Microgravity: The most significant factor is the microgravity environment of space. In microgravity, the brain receives conflicting signals from the inner ear, eyes, and other sensory organs. This sensory mismatch can lead to motion sickness symptoms like nausea and vomiting.
Adaptation Period: When astronauts first arrive in space, it takes time for their bodies to adapt to the weightlessness. During this adaptation period, which can last a few days, some astronauts may experience space motion sickness.
Vestibular System: The inner ear's vestibular system, responsible for balance and orientation, is particularly sensitive to changes in gravity. In microgravity, it can become disoriented, contributing to feelings of nausea.
To mitigate space motion sickness, astronauts undergo training and may use medications. Additionally, the brain eventually adapts to the new sensory inputs, and many astronauts report that their symptoms improve after a few days in space. However, not all astronauts experience space sickness, and individual susceptibility varies

Universe size comparison
The size of the observable universe is vast and difficult to comprehend. As of my last knowledge update in September 2021, the observable universe is estimated to be about 93 billion light-years in diameter. This means that light from the farthest objects we can observe has taken approximately 13.8 billion years to reach us since the Big Bang.
It's important to note that the observable universe is not necessarily the entire universe. It's the part of the universe from which light has had enough time to reach us since the universe began. The true size and nature of the entire universe are still topics of ongoing scientific research and exploration.
Keep in mind that these numbers are based on our current understanding of cosmology, and future discoveries may refine our knowledge of the universe's size and structure.

Top 15 best space exploration games
Certainly, there are several space exploration games that offer immersive experiences. Here are a few popular ones:
Elite Dangerous: This game offers a vast, realistic galaxy for you to explore. You can trade, mine, fight, and explore in an open-world environment with stunning graphics.
No Man's Sky: No Man's Sky provides a procedurally generated universe with billions of planets to explore. You can gather resources, trade, build bases, and interact with other players in a shared universe.
Kerbal Space Program: In this game, you manage a space program and design your own spacecraft to explore space. It's known for its realistic physics and a steep learning curve.
Starbound: While not purely a space exploration game, Starbound lets you explore procedurally generated planets, gather resources, build, and interact with various alien species.
Stellaris: This is a grand strategy game that allows you to manage an entire interstellar civilization. You can explore, expand, exploit resources, and engage in diplomacy and warfare in a vast galaxy.
Outer Wilds: It's a unique and award-winning game that combines space exploration with mystery-solving. You're stuck in a time loop and must explore a small solar system to uncover its secrets.
These games offer different experiences, from realistic simulations to more fantastical adventures, so you can choose one that suits your preferences for space exploration. Please note that the availability and features of these games may have changed since my last knowledge update in September 2021, so it's a good idea to check the latest information before making a choice

Jump from space world recored
#viral#fpr#The highest jump from the edge of space on record is the Red Bull Stratos mission, which took place on October 14, 2012. Austrian skydiver Felix Baumgartner ascended to an altitude of approximately 128,100 feet (39,045 meters) in a helium balloon and then made a freefall jump from that altitude.
During this jump, Felix Baumgartner broke several records, including:
Highest Altitude Jump: He jumped from the highest altitude ever recorded for a human freefall.
Fastest Freefall Speed: Baumgartner reached a maximum speed of approximately 843.6 miles per hour (1,357.6 kilometers per hour) during his freefall, which is faster than the speed of sound at that altitude.
This historic jump was a part of scientific research and garnered significant media attention, marking a remarkable achievement in the field of high-altitude and space-related skydiving.
