Does time actually slow down in space?

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.

What is the effect of matter on space-time?

Matter tells space how to curve, and curved space tells matter how to move. That’s the basic principle behind Einstein’s General Relativity, which linked, for the first time, the phenomenon of gravity with that of spacetime and relativity.

Is time distorted in space?

Any object distorts the fabric of space-time and the bigger it is, the greater the effect. According to the theory, matter and energy distort space-time, curving it around themselves. ‘Frame dragging’ theoretically occurs when the rotation of a large body ‘twists’ nearby space and time.

What is time dilation in space?

time dilation, in the theory of special relativity, the “slowing down” of a clock as determined by an observer who is in relative motion with respect to that clock.

Do black holes warp space time?

A black hole warped space-time so much that astronomers saw flashes of light from its far side. The black hole warped light from X-ray explosions on its far side, bending the light around toward Earth. It further confirms Albert Einstein’s theory that massive objects like black holes warp space-time.

What happens during radioactive decay?

Radioactive decay happens when an unstable atomic nucleus spontaneously changes to a lower-energy state and spits out a bit of radiation. This process changes the atom to a different element or a different isotope.

How long does it take for caesium to decay in humans?

This comparatively quick elimination means that only one nucleus out of 160 will decay inside the human body Spent reactor fuel contains other isotopes of caesium; particularly caesium 134, with a relatively short) half-life of two years and caesium 135 with a particularly long half-life of 2.3 million years.

Do nuclear decay rates change with temperature?

The debate over whether nuclear decay rates change with temperature is about to get hotter. In 1913, Pierre Curie and M. Kamerlingh Onnes measured the rate of decay of radium at room temperature and after being cooled in liquid hydrogen. Their conclusion was that the decay rate was entirely independent of temperature.

How long does it take for a 238-u nucleus to decay?

If you have lots of atoms of 238 U, then it is highly likely that in 4.5 billion years you will have close to half as many. But there is no way to predict when a particular (pun intended) nucleus is going to decay.
