What is space made of?

Outer space is not completely empty—it is a near perfect 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 usually regarded as being completely empty. But this is not true. The vast gaps between the stars and planets are filled with huge amounts of thinly spread gas and dust. Even the emptiest parts of space contain at least a few hundred atoms or molecules per cubic metre.

What's empty space made of?

Perfectly "empty" space will always have vacuum energy, the Higgs field, and spacetime curvature. More typical vacuums, such as in outer space, also have gas, dust, wind, light, electric fields, magnetic fields, cosmic rays, neutrinos, dark matter, and dark energy.

How was space created?

During the Big Bang, all of the space, time, matter, and energy in the Universe was created. This giant explosion hurled matter in all directions and caused space itself to expand. As the Universe cooled, the material in it combined to form galaxies, stars, and planets.

How cold is it in space?

The Cosmic Background Explorer (COBE) satellite has refined temperature measurements taken way back in 1964. According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).

Do we age in space?

In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.

How much time on Earth is 1 hour in space?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.

Who created the God?

We ask, "If all things have a creator, then who created God?" Actually, only created things have a creator, so it's improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed. Atheists counter that there is no reason to assume the universe was created.

Who created the earth?

Chapter 1. In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.

What was there before the universe?

In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that's what we've been told by physicists for the past several decades.

Can u breathe in space?

On Earth, humans have oxygen to breathe. But there's very little oxygen to breathe in space. Space is actually a kind of vacuum, which means there isn't a whole lot of matter, or stuff, out there between the planets and the stars.

What does space smell like?

In a video shared by Eau de Space, NASA astronaut Tony Antonelli says space smells “strong and unique,” unlike anything he has ever smelled on Earth. According to Eau de Space, others have described the smell as “seared steak, raspberries, and rum,” smokey and bitter.

Why is there no sound in space?

Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.

Does space ever end?

No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.

What is nothing in space?

With no particles or antiparticles, no matter or radiation, no identifiable quanta of any type in your Universe, all you'd have left is the void of empty space itself. To some, that's the true scientific definition of "nothingness."

Is space completely silent?

OK so wait, is space completely silent or not? While space is more silent than you could ever imagine, it's not completely devoid of sound. Sound waves cannot travel through space, but there are some infinitesimally small regions where sound can exist, under very specific conditions.

Why did God create us?

Because Heavenly Father wanted us to have the chance to progress and become like Him, He created our spirits, and He provided a plan of salvation and happiness that necessarily includes this earthly experience.

How did God create man?

Then the LORD God formed man of dust from the ground, and breathed into his nos- trils the breath of life; and man became a living being. In Genesis 1, God created by speaking the physical world into existence.

What did God create first?

On the first day, God created light in the darkness. On the second, He created the sky. Dry land and plants were created on the third day. On the fourth day, God created the sun, the moon and the stars.

Who is the 1st person in the world?

Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, adam is also used in the Bible as a pronoun, individually as "a human" and in a collective sense as "mankind".

How old is the Bible?

The first Biblical stories were passed down orally and only written down later by various authors. Most Biblical scholars believe the Book of Genesis was the first book to be written down. This would have happened around 1450 BC to 1400 BC. So perhaps about 3400 years or so ago.

How much do astronauts get paid?

The pay grades for civilian astronaut candidates are set by federal government pay scales and vary based on academic achievements and experience. According to NASA , civilian astronaut salaries range from $104,898 to $161,141 per year. Here are a few of the benefits offered to civilian astronauts: Health care.

What happens if you stay in space for 5 years?

Astronauts who have stayed in space for long periods have problems with their circulation and eyesight. That's in addition to losses in bone and muscle tissue. Kelly has collected fluid samples and undergone rigorous medical testing to document these changes over the course of his trip.

Why do you age slower in space?

This form of time dilation is also real, and it's because in Einstein's theory of general relativity, gravity can bend spacetime, and therefore time itself. The closer the clock is to the source of gravitation, the slower time passes; the farther away the clock is from gravity, the faster time will pass.
