Time Travel

Is time travel possible? According to some physicists it is. But there are some rules and regulations. You cannot travel back in time, or at least not to the time before the time machine is invented. You have to travel near the speed of light(which will probably end up killing you), or find a wormhole(which is actually hypothetical and may not really exist). So my answer to this question is a regretful 'no'. But then I'm no physicist. Which I am really glad about. Because they seem to love pointing out all the flaws in movies that don't obey the laws of physics. And that really pisses me off.
