What will an object look like if its time is accelerated?

Question

Physics

Let's imagine that we have some kind of magic device that speeds up time in a given volume, say, 10 times. Let's take a burning candle as an object. How will she look?
Light is like a stream of particles: now, in a unit of our time, particles began to arrive 10 times more. Those. we will see that the candle has become 10 times brighter, the fluctuations of its flame will also be faster, and the candle will burn 10 times faster.
Light is like waves: the crests of the waves will become more frequent, a frequency shift effect occurs, similar to the fast forwarding of a sound recording: all voices become high. In other words, instead of the orangey-yellow candlelight, we will see something closer to the ultraviolet. The brightness of the candle does not change, it will also burn out 10 times faster.
So, it would seem that option two is correct, because it has long been experimentally confirmedgravity red shift... . And there is a hypothesis that pulsars are stars in accelerated time. But questions still remain.
1. It turns out that such a journey is destructive for a person? Whoever wants to see the future will slow down his time several times, and the electromagnetic waves surrounding him will simply burn him, because ordinary light will become, for example, gamma radiation, etc.?
2. And what will happen to other types of matter? Indeed, in the general case of a change in the STV, there is a change in the frequency of de Broglie waves (see the link above), and if a person whose time is accelerated 10 times throws a coin into the surrounding space: it is clear that it will fly 10 times faster (from the point of view of external observer), i.e. the momentum will be 10 times stronger, but this is the view of classical mechanics, where all formulas with t received additional. coefficient, the wave nature of the particles that make up the coin is not taken into account.

Answer 1

Check out The Guide: The Hitchhiker's Guide to the Galaxy. There you will find the answer to the ultimate question of life, the universe and all that. ;-)

Answer 2

Write the Lorentz transformation for the given system, based on what you observe from rest. Funny things happen.
