Antwort Can you hear in space? Weitere Antworten – Can sound be heard in space

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.In space, no one can hear you scream. You may have heard this saying. It's the tagline from the famous 1979 science fiction movie “Alien.” It's a scary thought, but is it true The simple answer is yes, no one can hear you scream in space because there is no sound or echo in space.The simple answer here, of course, is yes: space is silent because it's a vacuum. After all, what our ears perceive as 'sound' is just a pressure wave that passes through a medium, be that medium a solid, liquid or gas, and agitates the molecules within it.

Is fire possible in space : But in space, air doesn't move around in convection currents as it does on Earth because, with there being virtually no gravity, warmer, less dense air won't rise. Without convection, fires aren't fed so quickly with fresh air. They are less intense and spread more slowly than fires on Earth.

Could you cry in space

Your eyes will definitely cry in space but the big difference is tears don't fall. So grab a hanky.

Can we talk in space : Sound requires a medium for propagation. Therefore, two astronauts floating close to each other in space will not be able to talk to each other without using any special device because in space there is vacuum ( no material medium).

Assuming you are floating freely in space the gun will work just as it does on Earth. However, the bullet will continue moving for many thousands of years, eventually coming to a stop due to the friction from the diffuse material found in 'empty' space (or when it encounters another object).

Headaches are a common and recurring problem in space, even for astronauts that don't experience them on Earth. Spaceflight can be a real headache — literally. Since the days of the Apollo program, astronauts have reported experiencing head pain during their stint in microgravity.

Does space have a smell

We can't smell space directly, because our noses don't work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.Astronauts can take cell phones to space, but they don't work like they do on the ground. We don't get cell service, but we can check our emails, conduct video calls, take photos, and listen to music.Fires can't start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.

Even fired straight up, a typical bullet will return to Earth in less than a minute. In space, of course, there is almost no air resistance or gravity to affect a bullet shot from a gun. So, a bullet retains its initial speed for much longer and will keep travelling until it either hits something or runs out of energy.

Do you feel sleepy in space : Even though astronauts are allotted about 8.5 hours for sleep every day, many of them have reported needing only about 6 hours to feel fully rested. Some specialists believe that this is because the body tires less quickly in weightlessness: the muscles don't have to work as hard as on Earth.

Does space have an end : One thing's for sure: the Universe does not have an edge. There's no physical boundary – no wall, no border, no fence around the edges of the cosmos. This doesn't necessarily mean that the Universe is infinitely large though.

What does space feel like

"In weightlessness, you are effortlessly floating, because all of the acceleration forces on you add to zero. The most comparable feeling is floating in water without the sensation of water on your skin. Because you feel so light, you can move about with the slightest amount of effort.

Is there Wi-Fi aboard the ISS Yes, there is a wi-fi network accessible to the devices that utilize the non-mission critical server. This includes the SSC laptop computers and tablets. There are also some payload and inventory sensors that utilize that network.Can astronauts watch Hulu or Netflix in space Astronauts can watch pre-recorded TV in space. Livestreaming is not an option. Think of what you do on Earth to prepare for a road trip or airplane ride − many people download movies or shows ahead of time to watch while traveling.

Can we use pencil in space : Pencil. While graphite is claimed to be a hazardous material in space because it burns and conducts electricity, two facts mitigate the risks: The graphite in pencils is mixed with clay during fabrication of the "lead" to help hold its shape, and would only burn at greater than 1,000 °C (1,832 °F).
