Is time dilation an illusion?
No, time dilation is not an illusion. It is fundamental to the structure of spacetime, and has been verified experimentally numerous times.
How Time is an illusion?
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. He posits that reality is just a complex network of events onto which we project sequences of past, present and future.
Why does time slow down when you move faster?
As light is spread out by the observer moving away from the source of the light time is decreased. The faster the observer moves the more light is spread out and time slows down. Time slows down as you travel faster because momentum bends the fabric of spacetime causing time to pass slower.
Is Reddit time dilation real?
The answer is that it’s the same. The forward light and backwards light travel away from you at the same speed. The speed of light is the same no matter who is observing it, so it can’t change when you jump on a train. Here’s where it gets funky.
Why does time stop at the speed of light Reddit?
In other words: the faster you move through space, the slower you move through time. If you move at the speed of light, this means your movement in through spacetime lies fully in the 3 space dimensions. Thus, if you travel at the speed of light through space, time stands still for you.
How much time passes on earth in a light year?
There are 6 trillion miles in a light-year (approximately), so the distance we need to go is 6 trillion miles / light-year times 4 light-years, or 24 trillion miles. So, this trip would take 1.2 billion hours. There are 24 hours a day and 365.25 days per year, so this time in years is 137 thousand years.
Why does time dilation exist Reddit?
It’s a side-effect of finite speed limit of particles in the universe. If you have a particle speed limit you must have time-dilation because if there is a speed limit that means that everything slows down including clocks which are made of particles.
