Using the concept of length contraction and time dilation explain how is it possible to travel a distance of 1mln light years during the life of a single person?

Realize that for a moving observer, distances will appear contracted. Say the distance from Earth to Planet X is 1 million light-years (as measured in the earth-planet frame). If you are zooming along in your rocket at a speed of 0.99c (with respect to Earth), what would you measure that distance to be? How long would it take you to cover it, according to your clocks?monp said:i' ve calculated that the light need 3,15*1010^13seconds (which is actually about 998858 and nearly six months)to travel a distance of 1mln light years( which is 9,46*10^21meters).

The lifetime of single person is about 70 years, which is 2,207*10^9seconds. The person to travle that distance in 70 years should have a velocity much bigger than speed of light which is actually impossible for me, also when this person reach the speed of light he or she will have the gravity of black hole, so I really can't imagine how is possible to travel such a big distance. please give me some explanation.

For a "stationary" observer who measures the distance to be 1 million light-years, the time for light to travel will be 1 million years. But not for a moving observer, who sees that distance "shortened" due to Lorentz contraction.malawi_glenn said:Light need one milion years to travel one milion light years.

Length contraction is a phenomenon in which an object's length appears shorter to an outside observer who is moving relative to the object. This effect is a consequence of Einstein's theory of special relativity and occurs when an object moves at high speeds close to the speed of light.
Time dilation is a concept in which time appears to move slower for an object in motion compared to an object at rest. This phenomenon is also a result of special relativity and occurs when an object's velocity approaches the speed of light.
Length contraction and time dilation play a crucial role in space travel, as they allow for objects to travel at high speeds without experiencing the effects of time and distance in the same way as objects on Earth. This allows for astronauts to travel long distances in shorter amounts of time and also explains why they age slower than those on Earth.
No, length contraction and time dilation are only noticeable at extremely high speeds close to the speed of light. In everyday life, these effects are too small to be observed and are only relevant in the realm of particle physics and space travel.
Length contraction and time dilation are two sides of the same coin and are interrelated. As an object's length appears shorter due to its high velocity, time also appears to slow down for that object. This is known as the time-space continuum and is a fundamental concept in Einstein's theory of special relativity.
