Step into the past or look into the future

Author H.G. Wells wrote about a time machine that whisked its passengers backward and forward in time.Would not it be great if we really could step into the past or future that easily?Time machines,of course,don't exist,but museums serve the same sort of purpose.some allow us to step back into the Prehistoric Age and learn about dinosaurs.other museums give us an idea of what cities might look like in the far-off future.
