What Is Outside The Universe? To answer the question of what’s outside the universe, we first need to define exactly what we mean by “universe.” If you take it to mean literally all the things that could possibly exist in all of space and time, then there can’t be anything outside the universe. What is
What Is Outside Of Our Solar System? But its exact nature just outside our solar system has been largely a mystery, principally because the Sun, all eight planets and a distant disc of debris known as the Kuiper Belt, are all contained within a giant protective bubble formed by the solar wind, known as the
What Is So Special About The Hubble Telescope? It is a very special telescope which orbits far above the Earth. Hubble allows us to see objects more clearly because it is above the clouds in Earth’s atmosphere. … Hubble is not only a powerful telescope, but it also carries cameras which allow scientists on Earth
What Is An Active Young Galaxy With A Black Hole At Its Center? Astronomers have concluded that quasars are active young galaxies with giant black holes in their centers. Black holes are the remains of the most massive stars when they die. A black hole is an object with gravity so strong that nothing, not
What Exists Outside Of Our Universe? The universe, being all there is, is infinitely big and has no edge, so there’s no outside to even talk about. … The current width of the observable universe is about 90 billion light-years. And presumably, beyond that boundary, there’s a bunch of other random stars and galaxies. What
What Existed Before The Universe? The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe. What came before the singularity? The universal origin story known as the Big Bang postulates
What Is In The Space? Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. What is space filled with? Space is not empty. A point in outer space is
What Did Astronomers Discover About Other Galaxies In The Early Twentieth Century? Telescopes in U.S. West revealed vastly larger, expanding universe. In 1923, Edwin Hubble found variable stars in the Andromeda nebula enabling him to gauge its distance. It turned out to be far from the Milky Way, demonstrating that it and many other nebulae
What Is Most Powerful Telescope In The World? James Webb Space Telescope Is there a telescope more powerful than Hubble? The James Webb Telescope is powerful. The Webb is the successor to Hubble, and it’s 100 times more powerful. … Hubble is in a very close orbit around the earth, while Webb will be 1.5
What Is In A Cosmic Void? Cosmic voids are vast spaces between filaments (the largest-scale structures in the universe), which contain very few or no galaxies. … Voids are believed to have been formed by baryon acoustic oscillations in the Big Bang, collapses of mass followed by implosions of the compressed baryonic matter. Do we
