A time machine that can travel back to time...

No there is not a time machine yet, because we haven't had any visitrors from the future. One of the laws of time machine creation is that you cannot go back in time before the moment of the creation of the time machine. So as long as we don't see any visitors, the machine does not exist

I believe in the physical and technical possibility of traveling between metaverses, as particle tests at the CERN have attested.
Researchers at the new CERN Particle Accelerator in Switzerland believe their machine can recreate conditions like the “big bang” which brought time and space into existence, and create baby black holes and wormholes; elements that many believe offer the best chance to validate or dispute the concept of traveling backwards in time.
Princeton University’s Richard Gott describes wormholes as shortcuts through space and time that connect two distant points, like a worm tunnel through an apple. “You jump into the wormhole and instantly pop out on Alpha Centauri; you’ve gone through a tunnel that connects two places in spacetime.”
Although today’s laws of physics cannot rule out time travel, the idea is laden with problems. Say we travel back in time and stop our parents from getting together. This would prevent us from being born; we could not exist and our journey in time couldn’t happen – scientists call this a paradox. We created a past different from the one that already exists.
Clearly, mischievous time travelers cannot change the present. People are not suddenly disappearing because a rerun of events has prevented their birth. Therefore, something is stopping time travelers from changing our present, and physicists Stephen Hawking, Michio Kaku, and others believe they know what it is – parallel universes.
This holds that we inhabit a universe with an infinite number of other worlds. If you travel through time and convince your parents to split, you will immediately be thrust into a parallel universe; one where you never existed. You become a visitor in this new universe, but you can never return to your original universe because you don’t exist there anymore.
The longing to hug a departed loved one or foil atrocities, are among the compelling reasons that keep the dream of time travel alive in the minds of many. However, assuming that nobody wants to get lost in a strange universe, an advanced civilization might find the following applications worth pursuing:
• Glimpsing into the future could allow humanity to become aware of dangerous threats in plenty of time to find solutions.
• Backwards time travel would enable us to scan minds of lost loved ones the night before they died, and with tomorrow’s technology advances, allow them to continue living in our time.
Though wormhole construction is beyond today’s knowledge, positive futurists believe that humanity will one day think with super-intelligent minds governed by physics, not biology; and over the next few millennia, could easily learn to harness these wonders.
We dream of breathtaking changes ahead as we approach the era when machines surpass human intelligence. We ponder how our “magical future” might unfold. What miracles will civilization accomplish? Will we develop exotic planets; discover aliens; travel through time? Only time will tell.

Time travel into the distant past is not possible...
Think about it, man builds time machine, man travels back in time to before he built the machine.
Hence the machine did not exist in the past, it occupied no space/time in the past.
Hence there is a paradox, to which the only solutions are:
- Time travel from the future to any time after the machine is built, hence the machine's past.
- Time is circular in nature, you travel into the far future and you arrive at the past.
Since nobody has visited us from the future, to our present (their past) as yet, it is safe to assume that present-past time travel is currently impossible.

No but I do believe in time travel, like on Jet Li's The One. Like worm holes that need to be predicted.

I already answered this same question from you next week, so I won't bother prepeating myself.

I don't think there is but I think there will be one someday.
