The Andromeda Galaxy (M-31), Magellanic Clouds, Milky Way galaxy, Triangulum Galaxy (M-33), Omega Centauri, and the Sagittarius Dwarf Spheroidal Galaxy are all visible to the naked eye. It is mostly gas, so its low density will make it float in water. The universe's acceleration also confirms Albert Einstein's theory of general relativity, and lately, scientists have revived Einstein's cosmological constant to explain the strange dark energy that seems to be counteracting gravity and causing the universe to expand at an accelerating pace. The initial “glow” of the Big Bang can be seen throughout space today as the cosmic microwave background radiation (CMB). According to the theory, this gave rise to bubble universes that could function with their own separate laws of physics. For NASA’s #YearInSpace mission, astronauts had to spend a year at the International Space Station. Planck's observations are the most precise views of the cosmic microwave background ever obtained.

The lack of gravity causes the discs between vertebrae to expand, making a subtle increase in height. 6. The moon’s craters at the southern hemisphere have temperatures that never rise above -238°C.

Here are some of the most surprising and interesting things about the universe we live in. There was a problem. For the next 380,000 years, as the infant universe expanded and cooled, everything was a hot, dense plasma and liight could not pass through it. Necessary cookies are absolutely essential for the website to function properly. That would result in the heat death of the cosmos.

However, once astronauts come back to Earth, gravity will compress their spine and revert their normal height. These low-frequency sounds can’t be picked up by the human ear, and include the hum of the universe expanding, the groan of shifting tectonic plates, and other sounds from planets and black holes. This is one of many unknown facts about space. Visit our corporate site.

There are billions of galaxies in the universe. [Full Story]. In 1998, the Hubble Space Telescope studied very distant supernovas and found that, a long time ago, the universe was expanding more slowly than it is today.

The universe is a vast space with many secrets and mysteries that are simply waiting to be found. [Full Story], The shape of the universe is influenced by the struggle between the pull of gravity (based on the density of the matter in the universe) and the rate of expansion. Only 5% of the matter in the universe can be seen. In 840AD Emperor Louis of Bavaria died of fright when experiencing an eclipse of the sun – this is when the moon moves between the Earth and the sun and a shadow falls over parts of the Earth. The age of the universe is roughly 13.7 billion years old. (Good thing we won’t be around by then.). The early universe was in a hot, dense state that cooled as it expanded.
