Wormholes play a huge role in science fiction. You can even find them in Spidersilk the novel. But, can they really help us travel through space and time? The quick answer is yes. An astronaut recently posted about time travel through a wormhole being entirely possible, but not in the manner you think. If you travel through a wormhole to a destination and back again your time may have only been a few decades, whereas Earth time may have been thousands of years. So, in a sense, you would have traveled through time.
