If you were to scream in outer space, the sound waves of your voice would not travel because there is no atmosphere or air to carry them. This means that your voice would remain unheard and inaudible.
In fact, you would not even be able to hear yourself, because there is no air to transmit the vibrations. However, if there were other people or objects in space that you were close to, such as on a space station or suit, then your voice could possibly be heard.
This is because sound waves could travel through solid objects and liquids, since their atoms are able to vibrate. Additionally, if you were filming with a microphone close to your mouth, you could record what you said in space.
Can people hear you scream in space?
No, people cannot hear you scream in space. This is because sound waves require a medium to travel, such as air, and there is no air in space. Instead, the vacuum of space is remarkably quiet and sound cannot travel through it.
This means that outside of a spacecraft, astronauts floating in space would not be able to hear anything outside of their own suits, and any sound generated from them, such as screaming, would also not be heard by anyone else.
However, people inside a spacecraft, such as on a space shuttle, would still be able to hear each other screaming. The sound would be contained within the spacecraft itself and not travel outside of it.
Can you hear someones voice in space?
No, you cannot hear someone’s voice in space. This is because sound waves require an atmosphere with air molecules to travel through in order to be heard. Since there is no atmosphere in space, the sound waves are unable to travel and are effectively “lost in space.”
On Earth, sound waves travel through the air until they reach our ears, but in space, due to the lack of air molecules, there is nothing for the sound waves to travel through in order to be heard. Additionally, space is a vacuum, meaning that sound waves actually compress, instead of expanding outward like they do on Earth.
You may be able to hear loud explosions of sound energy from spacecraft engines, or from asteroids and rocks that collide with one another, but these events are relatively rare and you would need to be very close to hear them.
What is the loudest thing ever in space?
The loudest thing ever recorded in space was a sound produced by the collision of two black holes which occurred 1.3 billion light years away in a distant galaxy. The sound is estimated to have been around one hundred times louder than an exploding supernova, and the equivalent of a trillion times the human hearing threshold of pain.
Scientists detected the sound in September 2015 after analyzing data from the Laser Interferometer Gravitational-wave Observatory (LIGO). This discovery marked the first observation of gravitational waves, providing compelling evidence for Albert Einstein’s theory of relativity.
The sound itself is believed to be composed of frequencies at between 35 and 250 Hz as well as higher frequencies of 1 to 5 KHz and lower frequencies from 30 to 500 millihertz (mHz). When this incredible sound traveled across space, it was so faint by the time it reached Earth that it’s unlikely that any human actually heard it.
Does it hurt to cry in space?
No, it does not hurt to cry in space. When astronauts are in space, tears can’t actually fall because there is no gravity. This is because tears are made of salt water, and in order for them to be able to run down one’s face, gravity needs to pull them down.
There can be tears in space though because the body still reacts to emotional triggers like sadness, and liquid can still form in a microgravity environment. But rather than falling off the astronaut’s face, it will more likely form a liquid spheres or teardrops on their face, often referred to as ‘crystalline tears’.
So despite the lack of gravity, it is possible to cry in space, although it won’t really look or behave like the tears we are used to on earth.
What sound Cannot be heard in space?
Sound cannot be heard in space because sound waves require a medium – such as air or water – to travel through. Since space is a vacuum, there is no air or liquid for sound waves to pass through. While it is often depicted that sound can travel through outer space, this is a misconception.
Additionally, sound is a vibration that is usually generated by something, like an explosion that travels through the air as sound waves and can be heard by other observers. Since there is no medium for these sound waves to pass through in space, nothing can be heard there.
Which 1979 sci fi movie had the tagline in space no one can hear you scream?
The 1979 science fiction horror film “Alien” had the tagline “In space, no one can hear you scream.” The film, directed by Ridley Scott and written by Dan O’Bannon and Ronald Shusett, follows the crew of the space commercial towing vessel Nostromo, who investigate a distress signal from an unknown planet.
The crew eventually encounter a hostile, violent creature, and must fight for survival against it. It stars Sigourney Weaver as Ellen Ripley, Tom Skerritt as Dallas, Veronica Cartwright as Lambert, Harry Dean Stanton as Brett, John Hurt as Kane, Ian Holm as Ash, and Yaphet Kotto as Parker.
The movie was met with critical acclaim upon its release, and was immensely successful both commercially and critically. It was nominated for several Academy Awards, and earned a special lifelong achievement award for creature designer H.R.
Giger. The film spawned three sequels and numerous spin offs, and remains one of the most popular and beloved science fiction movies of all time.
Is space completely silent?
No, space is not completely silent. In space, there is sound in the form of electromagnetic radiation, which is the movement of energy through a field, but the sound waves cannot travel through a vacuum because there is no matter for the sound waves to propagate through.
The sound waves become distorted, creating a type of background hiss. However, since the vacuum of space is so vast, the sound is very faint and usually drowned out by other, louder sources of noise.
This background hiss is known as the cosmic microwave background radiation, and it is caused by the Big Bang. Additionally, the sound of a rocket engine or other forms of machinery can be heard through space but the sound is quickly absorbed by the vacuum and disappears.
So, overall, space does not have complete silence.
Would a body decompose in space?
No, a body would not decompose in space because of the lack of oxygen, microorganisms, and moisture. Without these elements, a body cannot decompose in the same way it would on Earth. In space, a body may undergo the process of “mummification”, where the body is dehydrated and the soft tissue dries out.
This dehydration process stops the decomposition process, preserving the body in a near-perfect state. However, over time, extreme cold temperatures can cause the body to become brittle and break down into finer particles.
Therefore, while a body in space will not decompose in a traditional sense, it may slowly break down over time due to the extreme environment.
What does space smell like?
Space has no smell of its own. It is a vacuum with very little matter, so there is nothing to produce any kind of aroma. Astronauts who have gone into space have described the smell of space as being “smoky” or like “seared steak.”
This smell is believed to be produced by ozone, the same gas that gives the ozone layer around the earth its distinctive scent. However, the amount of ozone in space is very small, so the smell of space is usually barely noticeable.
The smell can also be affected by the materials used in the construction of the spacecraft, which may contribute to the smoky scent reported by some astronauts.
Why is it impossible to talk in space?
It is impossible to talk in space because sound waves need a medium to travel through, such as water or air, and space is a vacuum. Sound waves travel in waves and pass energy from molecule to molecule to make their journey.
In space, there are no molecules to pass the energy through, so sound waves have nothing to travel through, making it impossible for sound to exist in space. In addition, sound waves vary in frequency, but in the vacuum of space, there is no atmosphere to filter and change those frequencies, so they would be lost.
Without a medium and a frequency, sound simply cannot exist in space.
Why can’t we talk in space?
It is impossible to talk in space because there is no medium (like air) for the sound waves to travel through and be heard. In space, there is no air or other physical objects for the sound waves to bounce off of, so the waves are not able to travel and be heard.
This is why astronauts have to communicate with each other using radios and other means of communication like text messages. Without any medium, sound waves generated in space just travel in the direction they are created without diminishing in intensity.
Since there is nothing to prevent the sound waves from dispersing and being absorbed, the sound cannot travel long distances and be heard.
What is the famous astronaut quote?
The famous astronaut quote is attributed to the late United States astronaut and moonwalker Neil Armstrong, who said: “That’s one small step for man, one giant leap for mankind” upon taking the first human steps on the surface of the Moon in July 1969.
The quote has since become an inspirational and motivational metaphor for any brave or ambitious endeavor. It speaks to the incredible potential of human effort, and the idea that one single act or milestone can have a much larger impact or significance.
What did Yuri Gagarin said in space?
Yuri Gagarin famously said “Poyekhali!” (translation: “Let’s go!”) at the beginning of his historic mission in space. Of course, his words of excitement and anticipation were shared with the world, becoming one of the most quoted phrases of the Space Race.
Gagarin uttered those words after receiving the “go” from the launch pad officials in Baikonur and just moments before his Vostok 1 spacecraft lifted off, beginning his journey as the first human in space.
His sentiment has served as much-needed inspiration for countless aspiring spacefarers since then.
What did Neil Armstrong say when he was in space?
Neil Armstrong famously said “That’s one small step for a man, one giant leap for mankind” when he became the first human to step onto the surface of the Moon on July 20th, 1969. He was preceded by Edwin “Buzz” Aldrin, who became the second human to step onto the moon’s surface shortly after.
Armstrong before him famously said, “Houston, Tranquility Base here. The Eagle has landed” when they first touched down on the lunar surface. Armstrong was quoted months later as saying this iconic phrase was something he’d been thinking about for quite some time as he had been intensely preparing for the moment.
