What happens if you take off your helmet in space?
Removing the helmet would leave permanent ear damage and the lack of oxygen would damage many organs. Also, if the astronaut is in a very cold part of the universe, the astronaut would start to freeze. While low pressure would lead to the boiling of his blood, saliva and in the end organs.
What happens to water in space?
Water poured into space (outside of a spacecraft) would rapidly vaporize or boil away. In space, where there is no air, there is no air pressure. As air pressure drops, the temperature needed to boil water becomes lower. In space, because there is no air pressure, water boils away at an extremely low temperature. How will the universe end? The Big Freeze. Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. If the expanding universe could not combat the collective inward pull of gravity, it would die in a Big Crunch, like the Big Bang played in reverse.
What is at the end of space?
Most of that space is almost completely empty, with only some stray molecules and tiny mysterious invisible particles scientists call "dark matter." Using big telescopes, astronomers see millions of galaxies out there ? and they just keep going, in every direction. What can we see in space at night? A clear night sky offers an ever-changing display of fascinating objects to see - stars, constellations, and bright planets, often the moon, and sometimes special events like meteor showers.
How old is the black hole?
At more than 13 billion years old, the black hole and quasar are the earliest yet seen, giving astronomers insight into the formation of massive galaxies in the early universe. How many light years away can we see? 46 billion light years In actuality, we can see for 46 billion light years in all directions, for a total diameter of 92 billion light years.
- What happens if an astronaut floats off in space?
It rains diamonds on saturn.
- What happens if a nuke goes off in space?
Steven McAuliffe is a federal judge in Concord, New Hampshire. Steven has two children who are grown up.
- What happens if the Earth gets knocked off its axis?
The blue color of the planet is due to the absorption of red and IR light by Neptune's methane atmosphere. Clouds elevated above most of the methane absorption appear white, while the very highest clouds tend to be yellow-red as seen in the bright feature at the top of the right-hand image.
