Is there really no sound in space?
Space Environment So, in order for sound to travel, there has to be something with molecules for it to travel through.
On Earth, sound travels to your ears by vibrating air molecules.
In deep space, the large empty areas between stars and planets, there are no molecules to vibrate.
There is no sound there..
Is it better to have an upstairs or downstairs apartment?
Pricing – Generally upstairs apartments are more expensive than downstairs. So if pricing is super important, one of the benefits of living downstairs is a slightly lower rental price. … Keep in mind upstairs apartments are generally warmer than downstairs since heat rises.
Do sound waves go up or down?
Top: Sound waves are longitudinal waves: the air moves back and forth along the same line as the wave travels, making alternate patterns of compressions and rarefactions. … Sea waves travel as up-and-down vibrations: the water moves up and down (without really moving anywhere) as the energy in the wave travels forward.
Can you hear sound on the moon?
However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don’t interact with one another). Thus there is no sound on the Moon.
Can you hear yourself 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.
Is it better to sleep in silence or with noise?
No, really. While it may seem a little hard to believe, perfect silence can keep some people from dropping off and enjoying a good night’s sleep. … Sounds of this sort work by creating a level of steady, consistent background noise that can help to mask different sounds that might otherwise wake you up during the night.
Should you play white noise all night?
White noise is great for use at nap time and during the night – but be careful about relying on it too heavily. For one thing, you want your child to gradually become accustomed to all of the customary sounds in your home.
Can gravity bend time?
Gravitational time dilation occurs whenever there is difference in the strength of gravity, no matter how small that difference is. The earth has lots of mass, and therefore lots of gravity, so it bends space and time enough to be measured.
Can sound waves affect light waves?
Hi Courtney, Light does not really affect sound. Sound is made of vibrations (aka rapid pressure fluctuations) in air, water, or solid material. … Now, the timescale (for example, the oscillation speed or the wave speed) for light is much faster than that for sound, so sound doesn’t even notice when light is around.
Can you hear gravity?
All the gravitational waves we have heard so far are in the audio frequency range for the human ear: we really could hear them if our ears were sensitive enough, but real signals are just too quiet. … Gravitational wave detectors are supersensitive microphones for the sounds of space.
Can waves have mass?
The water itself has mass, but the wave has no mass. … In this way, waves can have no mass but still carry momentum. In addition to being a particle, light is also a wave. This allows it to carry momentum, and therefore energy, without having mass.
Is sleeping with a sound machine bad?
The answer again, is YES. White noise machines benefit a baby by promoting sleep. However, it’s important to keep noise at a safe level for a baby and adults. If white noise machines produce sound above safe decibel levels, then they can be harmful.
What can sound not travel through?
vacuumSound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
Does gravity affect light waves?
Yes, light is affected by gravity, but not in its speed. … It can bend light (which includes effects such as gravitational lensing), and it can change the energy of light. But it changes the energy by shifting the frequency of the light (gravitational redshift) not by changing light speed.
Why do sounds get louder at night?
During the day, the sound bends away from the ground; during the night, it bends towards the ground. … So to summarise, sound is louder at night due to the change in the direction of sound refraction, which is caused by the reversal of the temperature gradient from day to night.
Is gravity stronger than light?
Kopeikin and Fomalont concluded that the speed of gravity is between 0.8 and 1.2 times the speed of light, which would be fully consistent with the theoretical prediction of general relativity that the speed of gravity is exactly the same as the speed of light.
What is the fastest thing in the universe?
And, while light is still by far the fastest thing in the universe, moving at a staggering speed of 299791.82 km/h, the following list contains some of the other closest things to reach that title of “World’s Fastest.”
Can upstairs neighbors hear my music?
So, sorry to give bad news, but my answer is: probably… Yes, the neighbors can hear you upstairs and beside you also, sounds travel upwards also especially voices up and besides, so if I were you I would speak lightly about important subjects, social security numbers, and other important topics.
