Time freezes at the edge of black hole.
Does it mean we could live forever?
Whenever you think about time dilation, in relativity theory,
keep in mind that the theory is not about you.
It is about what others see.
As far as you are concerned, no matter where you are,
or how you move, time will always appear to pass,
as it always does.
Imagine we are in a super fast spaceship.
Every second of our life, is a thousand years on earth.
Does that mean we will live forever?
No.
We can still expect a normal human lifespan measured by our own watch and calendar.
Billions of years would pass on Earth.
But you will not experience millions of years.
Only a few decades as usual.
Suppose you are inside a very powerful gravitational field.
There will be extreme time dilation.
Others on Earth will see you age slowly, and will see your clock tick slowly.
As far as you are concerned, your clock ticks normally,
and you age exactly as fast as you would normally.
The main point is,
relativity theory is not about what happens to you.
It is about others who are observing you.
