After death can be anything

[kokporn]

Our world is so vast and varied. There are millions of galaxies in the world that have their own laws of physics. What will happen to our dead cells when the sun explodes? What will happen to them when our universe collides with Andromeda? What will happen, for example, in 10 billion years? Maybe to be anything at all. I'm so scared.

Well the laws of physics don't change, not at least in the visible universe, there are black-holes of course but they governed by rules we do not yet understand rather than the lack of them.
The atoms making up the molecules and cells in your body will disperse over time and eventually be part of other organisms. Then after the sun expands and basically vaporizes the earth sending everything along with its own outer layers on a trajectory into deep space, perhaps to form gas clouds and collapse forming new stars.

A calming thought, basically every atom in your body and our planet, apart from hydrogen and helium most likely formed in cores of supermassive stars that went supernovae billions of years ago. So you're pretty much made from star dust.

what will happen? the worst and hopefully the best, too!

There are two options, a respawn button and a "go to menu" button

You forgot the third, which I'd prefer, the power button.

If you subscribe to Kants ideas about space and time being pure intuitions, not as properties of the world in itself ... the observable universe would, in a way, come to an end with your death – at least the one you exclusively lived in, the one in your head.
