A couple of guys in Italy have figured out the physics for a time machine.?

更新:

Seems like all you need is a super-precise arrangement of negative energy over a region of about 100 light-years.

    I'll believe that when I see it. I hope they show it to me yesterday.

    The only reasonably reliable 'time machines' are either hanging on the wall, beside the bed, showing on electronic devices or worn on your person, etc.

    Clocks and watches work, nothing else does.

    I believe that just like I believe that you are beautiful.

    Guys on Star Trek figured out the physics of Warp Drive.

    So, as Captain Picard said, "Make it so." What's holding the back?

    They did figure it out only next year. But after trying the machine out they inadvertently sent themselves thousands of years forwards so the machine won't be invented until we catch up with them.

    I doubt "negative energy" and I doubt an area measured in light years, which is a measurement of distance, not area.

    The couple of guys in Italy have figured balogna.

    That's ridiculous. We are three-dimensional, and time travel is impossible for us.

    The only time travel that is possible is to travel into the future. Once something has happened its done. There is no way of reversing it.
