Are the deceased still with us? Physicist Sabine Hossenfelder responds #shorts

there's another way to look at this idea

that people who have sadly deceased do

in some sense still exist and it's

because of the way that all the

fundamental laws of nature that we know

work they don't destroy information the

only thing that they do is that they

rearrange the meta and radiation and

everything that's in the universe they

just give you the rules for how to put

them in different places with different

velocities but you can apply those rules

forward and backward and this means that

you can in principle if you had a really

really good computer you could always

find out what happened earlier so in

this sense information cannot get

destroyed it can however become for

practical purposes impossible to

retrieve
