Why is space infinite?
Space isn't definitively proven to be infinite, but current observations suggest it's either truly infinite or incredibly vast, with its "infinity" stemming from the fact that it has no observable edge and continues to expand everywhere, meaning there's always more space, even if it's finite in volume but curves back on itself (like a sphere or torus). The expansion means distances between galaxies increase, but it doesn't necessarily expand into anything, as space itself is stretching.How does space just never end?
So why do scientists think that space goes on forever? It's because of the shape of space. Our part of space, or the observable universe, has a special shape: it is flat.Is space 100% empty?
Space, or outer space, is a vast, near-perfect vacuum largely devoid of matter. This vacuum contains very few particles compared with Earth's atmosphere. However, it's not entirely empty. Space is dotted with scattered matter called the interstellar medium, which includes hydrogen and helium atoms.How can the space be infinite?
How can the universe be infinite if it started expanding 13.8 billion years ago? If the universe is infinite, it has always been infinite. At the Big Bang, it was infinitely dense. Since then it has just been getting less dense as space has expanded.What is beyond the space?
Outside the bounds of our universe may lie a "super" universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever. Lying hundreds of billions of light years from us could be other island universes much like our own.The Paradox of an Infinite Universe
Why is 95% of the universe invisible?
Surprisingly, normal matter turns out to be only a small fraction of what the Universe contains. 95% of the Universe is made up of dark matter and dark energy. These are words astronomers have come up with to give a name to the mysterious, invisible side of the Universe.What will happen in 1 sextillion years?
In 1 sextillion (10^21) years, the universe will be in the "Degenerate Era," far past the death of stars and galaxies, with only black holes, neutron stars, and cold white dwarfs remaining, as all normal matter slowly decays into iron, making the universe a dark, cold, and nearly empty place, though some speculative theories suggest advanced civilizations might build artificial systems or new universes.What does God say about the universe?
According to major religious texts like the Bible and Quran, God is the ultimate creator of the universe, bringing it into existence "out of nothing" (ex nihilo) through divine words or command, establishing order and physical laws for celestial bodies like stars, the sun, and moon, and making it vast and complex for His purposes, often to be appreciated and governed by humanity. Key themes include God's power as the source, the universe's ordered structure, and humanity's place within it, though specific interpretations on age and other aspects vary.Does space end or go on forever?
Scientists don't know for certain, but evidence suggests space either goes on forever (infinite) or curves back on itself (finite but unbounded), meaning you can travel forever without hitting an edge, but might return to your starting point. Most current understanding points to a flat, infinite universe that continues to expand, but some models suggest a finite, closed universe like the surface of a sphere, where traveling far enough brings you back around. There's likely no physical "end" or wall to space.Is God infinite or finite?
For example, when we call God immutable, we are saying that He is not subject to mutation; that is, He does not change. Likewise, in defining our Father as infinite, we are saying that He is not finite. To be infinite means God's being and greatness have no limitations.What kills first in space?
But eventually, the lack of oxygen will take its toll. One by one, your major organs will shut down. After only a handful of minutes you will suffer complete organ failure, otherwise known in the medical community as death.Why is 1 hour 7 years in space?
The statement that one hour in space is equivalent to 7 years on Earth is not accurate. Time dilation, a concept from Einstein's theory of relativity, does affect time in space relative to different reference frames, but the effect is typically negligible for most space travel scenarios within our solar system.Can we feel pain in space?
Yes, you can feel pain in space, and it's quite common, especially back pain and headaches, due to physiological changes from microgravity like spinal elongation and fluid shifts, although the pain often lessens as the body adapts. Astronauts experience issues like "space adaptation back pain" and "space headaches," stemming from changes in disc pressure and cranial fluid, which can be significant but usually improve after the first few days or weeks in space.Do we see 8 minutes in the past?
The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us. Not much changes about the Sun in so short a time, but it still means that when you look at the Sun, you see it as it was 8 minutes ago.

No, the Bible doesn't explicitly forbid space travel; instead, many biblical passages, like Psalm 8:6, suggest humans have dominion over creation, which some interpret as including space, encouraging exploration as a way to understand God's glory, though some verses like Obadiah 1:4 are sometimes debated, generally seen as warnings against pride, not space exploration itself.What will happen in 2026 in space?
2026 is set to be a huge year in space, marked by NASA's Artemis II mission sending the first crew around the Moon in decades (April), major test flights for SpaceX's Starship, and the launch of new telescopes like China's Xuntian and NASA's Nancy Grace Roman Space Telescope, alongside lunar landers from Blue Origin and Firefly, and missions to Mars. Key events include crewed lunar flybys, commercial space station development, asteroid sample returns, and new exoplanet research, promising a mix of human exploration and scientific discovery.How much longer do humans have left?
No one knows exactly how long humans will last, with predictions ranging from a few centuries due to self-inflicted risks like climate change, nuclear war, and AI, to millions or even billions of years if we spread to space and overcome threats, with some statistical models suggesting extinction within 8 million years or even as soon as 760 years, but optimistic views point to Earth's habitability for another billion years if we manage our challenges.What state is 99.9% of the universe in?
While rarely encountered on Earth, it is estimated that 99.9% of all ordinary matter in the universe is plasma. Stars are almost pure balls of plasma, and plasma dominates the rarefied intracluster medium and intergalactic medium.What happens every 176 years in space?
Every 176 years, the outer planets (Jupiter, Saturn, Uranus, Neptune) align in a rare configuration that allows spacecraft to use their gravity for "slingshot" maneuvers, enabling missions like NASA's Voyager probes to visit all of them efficiently in a single journey, a phenomenon crucial for deep space exploration.Does NASA believe in God?
No, NASA as an organization doesn't have beliefs; it's a U.S. government science agency focused on space exploration, but its diverse employees hold a wide range of personal beliefs, with many astronauts and scientists being religious, while others are not, reflecting the general population's mix of faiths and non-belief, often discussing spirituality in relation to space discovery.Did God create other worlds?
Whether God created other worlds is a matter of faith and interpretation, with scriptures like Genesis suggesting a single universe for humanity, while some mystical traditions and modern interpretations hint at other realms; the Bible doesn't explicitly confirm life on other planets but leaves room for other creations, with some viewing the vast cosmos as God's glory and others seeing it as solely for Earth's purpose.Does the Bible talk about UFOs?
No, the Bible doesn't mention modern "UFOs" or aliens from other planets, but some people interpret prophetic visions, like Ezekiel's fiery wheeled craft, as proto-UFOs, while many theologians see them as descriptions of God's glory, spiritual beings (angels/demons), or symbolic representations of divine power and judgment, with the Bible focusing on God's relationship with humanity, not extraterrestrial visitors.Why will the Sun disappear in 2027?
That's because the eclipse, which is set for Aug. 2, 2027, will blanket the Earth in darkness for a whopping (in eclipse time) 6 minutes and 23 seconds, with a path of totality — the area where the moon completely blocks the sun's light — running from Europe and North Africa through the Middle East.Will humans be alive in 3000?
Yes, it's highly likely humans will still exist in the year 3000, though they'll likely be vastly different due to technological and environmental changes, with many experts predicting humanity will have spread beyond Earth, making extinction highly improbable, despite risks like climate change or pandemics.How much age is left of sun?
The Sun has about 5 billion years of stable life left, as it's currently in its middle age, fusing hydrogen; after this, it will expand into a red giant, potentially engulfing Earth, before eventually shrinking into a white dwarf, leaving our solar system in about 10 billion years. Life on Earth, however, might end much sooner, possibly within 1 billion years, as the Sun gradually brightens and becomes too hot for liquid water, even before its red giant phase.
