Do astronauts age faster?
So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time.
And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth.
That’s because of time-dilation effects..
Does gravity affect time?
This effect is known as “gravitational time dilation”. … Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.
Does gravity bend sound waves?
Sound waves are pressure waves and depend on density so gravity which stratifies the atmospheric density affects sound waves through that. In solids and liquids to the extent that gravity stratifies them it will change the behaviour of sound waves.
What does gravity change with?
Gravity is determined by how much mass a given material has, so the more mass an object has, the stronger its gravitational pull. … “The Earth’s gravity field changes from one month to the next mostly due to the mass of water moving around on the surface,” said Watkins.
Does gravity decrease as you go higher?
Yes. Gravity lessens as we gain altitude. The formula for gravity is based on the radius distance between the two objects (as measured from the centers of each object). As the distance increases, then the gravitational attraction decreases, all things else being held the same.
Can time be stopped?
The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” The practice is, admittedly, a bit more difficult. … To phrase this tenet in a more friendly manner, it means that a light beam’s speed remains unchanged even if the observer moves relative to it.
