As for time travel, you do this with black holes or (hypothetical) wormholes. The problem with black/wormholes is that using one for time travel is like flying a hang glider into a tornado. Looks good on paper, but it is gnarly inside black holes and wormholes. You might certainly arrive in another time, but you would arrive as a cloud of radiation and subatomic particles.
As for life elsewhere in the Universe, use the Universe as a computer for the answer. To do this take a rock and hold it in your hand. Let it go. If it falls and hits the ground, there is life elsewhere in the Universe. This is because the Universe is designed out to 30 or more decimal places to make life possible (google 'anthropic cosmological principle'). Change any physical constant of nature by quadrillionths of a percent, and life is impossible. The rock experiment demonstrates that the universe is functioning correctly and, therefore, life exists elsewhere with Probability-1.
Hawking is a real smart guy, but he is a bit of a showman and it is no longer the 1990s. There are other smart guys out there.
