#Observable Space

The observable universe is 93,000,000,000 light years wide. Not the full universe. Just the part where light has had time to reach us. Beyond that — we have no idea. It could go on forever. The nearest star to Earth after our own Sun is Proxima Centauri — 4.24 light years away. At the speed of our fastest ever spacecraft, Voyager 1 — it would take 73,000 years to get there. That is our closest neighbour in space. The zoom you just watched started at the outer edge of everything humans have ever observed. It ended at you. And it still didn't show you how big it actually is. 👇 Did the size of the universe ever cross your mind before this? #universe #space #astronomy

The visible universe, often called the observable universe, spans a diameter of about 93 billion light-years. This size accounts for cosmic expansion since the Big Bang roughly 13.8 billion years ago. Its radius reaches approximately 46.5 billion light-years from Earth in any direction, forming a spherical region defined by the farthest light that has reached us. The comoving distance to the cosmic microwave background—the edge of what we can see—is about 45.7 to 46.6 billion light-years. Diameter totals around 93 billion light-years (or 28.5 gigaparsecs), vastly larger than the naive 27.6 billion light-years expected without expansion. Light from the universe's early days has traveled for 13.8 billion years, but space itself expanded during that time, stretching distances. Hubble's law shows objects receding, so today's proper distance to those sources is now ~46 billion light-years away. The observable portion grows by about 1 light-year per year as more light arrives, though we'll never see beyond this horizon.

The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m). https://en.m.wikipedia.org/wiki/Observable_universe The universe is everything. It includes all of space, and all the matter and energy that space contains. It even includes time itself and, of course, it includes you. Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons. https://science.nasa.gov/exoplanets/what-is-the-universe/ Video credit: @astroscienceig 👑 Subscribe @theoretical_mass to be first for all posts and get exclusive content. 🎯 Follow @theoretical_mass For More Knowledgeable Astronomical Contents. 🔔Turn On The Post Notification For Never miss any updates from @theoretical_mass 👤Tag Your Friends To Show This 💡If You would Like to read our post daily Then Follow 👇 @theoretical_mass @theoretical_mass @theoretical_mass #blackhole #nasa #space #universe #astronomy #astrophysics #science #physics #cosmos #spacex #quantumphysics #galaxy #cosmology #hubble #earth #stars # #mars #theoreticalphysics #elonmusk #raiders #blackholes #sciencefacts #stephenhawking #facts #physicsmemes

EARTH FROM SPACE 🌏 Part 347 ✨FUN FACT : During a spacewalk outside the ISS, astronauts are never truly “alone” even if radio contact briefly drops, they’re protected by multiple backups. Their suit has redundant radios, a safety tether to the station, and a small emergency jetpack called SAFER that can fly them back if they drift away. Losing comms would be scary, but the bigger danger is losing your tether because in orbit, even a tiny push can send you silently drifting into space. 🧑‍🚀 Follow @spacegenerationx for more space content #nasa #space #astronaut #hurricane #spacex

The observable universe is estimated to be about 93 billion light years in diameter based on current cosmological models. Because of the expansion of space we can only see a portion of the entire universe and its true size may be far larger or even infinite. This concept is based on the Big Bang and ongoing research in astrophysics that continues to reshape our understanding of space and reality.

The Observable Universe vs. the REAL Universe 🌌 What we can see is only a tiny fraction of what exists. The observable universe is limited by how far light has had time to travel since the Big Bang—but beyond that horizon, space likely continues far farther, possibly infinitely. The real universe may be vastly larger, filled with galaxies we will never observe, forever beyond our reach. #space #universe #astronomy #cosmology #spacefacts #science #cosmicmysteries

👨‍🚀Astronauts' bodies absorb radiation equivalent to 8 chest X-rays per day. In 6 months, that’s more than most humans receive in a lifetime. On the ISS orbit (Earth at 28,000 km/h) — they witness 16 sunrises every single day. Muscles forget gravity exists. Bones lose 1–2% density per month. The spine stretches — astronauts return up to 3 cm taller. And yet — they keep going back. Because some views are worth the risk. #space #earth #nasa

Earth is a small planet moving around an average star in the Milky Way galaxy. From a space perspective, it is a tiny point with no visible lines, labels, or divisions. Its size is extremely small when compared to the scale of space. The Milky Way is one galaxy among hundreds of billions spread across the observable universe. Each galaxy contains countless stars, planets, and clouds of gas, separated by very large distances. On this scale, individual locations become almost unnoticeable. The universe follows steady natural laws over very long periods of time. Stars form, change, and fade, while galaxies slowly shift through space. These processes continue calmly and consistently, far beyond human timelines. Most human worries exist for a short time and within very small spaces. When compared to the size and age of the universe, these concerns are limited in scope and duration. Seeing our place in the universe can help reduce constant worry. We live briefly on a small planet inside a much larger system, and understanding this scale can bring perspective and calm. This video is for educational purposes only.

Earth is surrounded by thousands of satellites. Some are active, powering GPS, internet, and weather tracking — others are inactive, adding to space traffic. Most orbit close to Earth, and the number keeps rising with mega-constellations. #Satellites #EarthOrbit #SpaceTraffic #LowEarthOrbit #SpaceFacts
