Can you have a spark I space?
Lighter flints would probably not spark in space because the small metal particles need oxygen in the air to glow brightly however a fast grindstone grinding steel may produce rather dim sparks because the particles of metal ripped off by the grindstone are initially red hot but they cannot burn in space.Can you self propel yourself in space?
If you are stationary in space with nothing around you to push off on, you cannot move yourself by pushing on yourself. But you can twist your body around its center of gravity - you just can't move your center of gravity. On Earth, we can walk forward because we push on the Earth and it pushes back on us.Can you create a spark in a room without oxygen?
A fire cannot burn without oxygen. You can show this for yourself, in fact: if you light a small candle and then put a clear glass upside-down over that candle (without touching the flame), you can watch the flame slowly extinguish as it uses up all of the oxygen that you have trapped around it with the glass.Do you explode if you go into space?
Humans don't explode in space. Even though outer space represents a lack of air pressure, which usually counters the internal pressure in our bodies, our tissue is strong enough to handle the imbalance.Can a spark exist in a vacuum?
It is impossible for a visible spark to form in a vacuum. Without intervening matter capable of electromagnetic transitions, the spark will be invisible (see vacuum arc).The Spark Of Space Activation | Jason Page | TEDxLewisham
Can electricity travel in space?
Answer 1: Electricity doesn't exist in space in the usual way we think about it, namely electrons flowing in a wire. But that's only because space normally doesn't have wires. If you take something electronic up into space, it will work just fine (as long as you keep it at a normal temperature...How far can a spark travel?
A spark will spontaneously jump across a gap of 1 cm if there is a potential difference, of about 10,000 V across it. A larger gap needs a bigger potential difference so a spark will jump across a 3 cm gap if there is a potential difference of 30,000 V and so on.Would your eyes pop out in space?
NASA makes it clear that your body wouldn't explode and your eyes wouldn't pop out of your head like many science fiction movies suggest. However, you would swell up and get really painfully puffy.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.Would a dead body decompose in space?
Halting decompositionAnd bacteria from the gut would still devour the soft tissues. But these bacteria need oxygen to function properly and so limited supplies of air would significantly slow down the process.
Will pure oxygen burn?
The technical reality is that the oxygen doesn't burn,” said Mark Bruley, vice president for accident and forensic investigation at ECRI Institute. “It's a subtlety of the physics of fire. Oxygen makes other things ignite at a lower temperature, and burn hotter and faster. But oxygen itself does not catch fire.”Why is h20 not flammable?
Water is made up of two elements, hydrogen and oxygen. Hydrogen is flammable, but oxygen is not. Flammability is the ability of a combustible material with an adequate supply of oxygen (or another oxidiser) to sustain enough heat energy to keep a fire going after it has been ignited.Can air be set on fire?
Air will never spontaneously combust, nor can it be made to burn non-spontaneously. Air is mostly nitrogen, which is not flammable. Nitrogen is also non-reactive in general, so it doesn't support the combustion of other materials, either.Can I fart in space?
Speaking to tech blog, Geekadelphia, he explained: "If you fart...the gas stays right there. It doesn't go anywhere. "It hovers right around there.” Robert Frost, Instructor and Flight Controller at NASA, assured Quora readers that "it happens."Is it impossible to burp in space?
On Earth, gravity pulls liquids and solids to down to the bottom of our digestive systems, while gases stay up top and get forced back up the esophagus as a burp. That can't happen in space. Without gravity to separate them, “the air, food and liquids in your stomach are all floating together like chunky bubbles.Why can't astronauts cry in space?
Astronauts can't cry the same in space as they do on Earth.Your eyes make tears but they stick as a liquid ball. In fact, they sting a bit. So — space tears don't shed." Unless an astronaut wipes that water away, tears in space can form a giant clump that can break free of your eye, as The Atlantic explained.
Do you 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.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.How cold is 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).Is blood blue in space?
This leaves only high-energy blue light to be reflected from our maroon veins. So, if you cut yourself in space, your blood would be a dark-red, maroon color.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.What happens if you expose your skin in space?
The nitrogen dissolved in your bloodstream near the surface of your skin will collect itself into little bubbles. These bubbles expand, puffing you out to around twice your size, starting at your hands and feet and moving in. It's a real thing: it's called ebullism.How hot is a spark?
It depends on the kind of sparkler, but the temperature of these sparks can be anywhere from 1800°F to 3000°F (1000°C - 1600°C). How hot is that?How many volts do you need to jump an air gap?
In order to jump a clear air gap, it takes about 30,000V per centimeter or about 75,000V per inch. The sustaining voltage is reduced when the gap is ionized. That's in normal air, at normal temperature, humidity and air pressure.How is a spark created?
The rapid transition from a non-conducting to a conductive state produces a brief emission of light and a sharp crack or snapping sound. A spark is created when the applied electric field exceeds the dielectric breakdown strength of the intervening medium.
