This doesn't make me wrong about science, it's just that by then it will be will not have the data to figure out what happened. You can't see the other galaxies anymore. That's not a problem with science, that's a problem of insufficient data. It may be the case an intelligent could figure things out by looking at the evidence available to them within their finite, expanded universe. Space will still be expanding, there will still be red shift, there will still be gravity. And science will be the tool to use to figure this stuff out.
