Exactly, the more we learn the more we realize what we don't know!

Why is it surprising that old(er) scientific theories may be proven false?

Just remembered Time Bandits cracked me up in university. And apparently got 5 stars on rotten tomatoes. If you haven't seen this masterpiece, get on it

This isn't just a scientific theory, it was supposed to be one of the universal laws of existence.

What? Freezing yourself for a hundred years is a HUNDRED years! You getting on this train for a week is a WEEK of your life, yet a hundred years have passed just outside the door. Your are NOT frozen or in suspended animation!

I disagree because in a sense you are. It's well know that the closer you get to the speed of light, the slower time moves for you. As the outside observers' time flashes before your eyes, that observer would see you as being frozen, or near to it. It is more and more accepted that backward time travel is theoretically not viable, thus (in my opinion) show that you cannot move though time itself in the same way we move though the three dimensions.
So if time travel (as we call it) is closer to being improbable, then how do we move forward though it? One of the ways we can get around this problem is be freezing yourself... although impractical. For you no time would have passed, both physically and mentally. Another way of trying to "go into the future" is by slowing yourself down so slow as to have weeks feel like seconds, years feeling like minutes and so on. The train example is perfect for demonstrating this since, while on this train, time has been significantly slowed to a crawl for you as seen by an outside observer. You would perceive that things are normal for you, but if you're able to observe outside the confines of your time bubble you'd simply observe everyone or thing extremely sped up in movement and in aging.
So in the end you're not traveling though time really, you're just finding a way of letting everyone else's time pass you by. If it were true time travel, then you would be projected instantly and not live for a week while a hundred real years pass.
Magnetonium
The scope and scale of this large experiment would no doubt create conditions in which data and observations would be a bit bent and off scale. From what I remember as an example - at the very beginning of the Big Bang, the explosion was powerful enough that at one point early on the matter expanded a bit faster than the speed of light. Amount of force and matter involved, go figure. Very powerful and destructive event.
There is too much hype here (and news are typically sensationalized or overhyped anyway), time travel is not possible. In this case, neutrinos allegedly were faster than speed of light by a small tiny fraction of a BILLIONTH of a second. Thats not really much.
These were results from over 15,000 particles. Only neutrinos went a tiny bit faster. They'd need a lot more than just neutrinos if they want to time travel - which can create plenty of paradox scenarios in the first place.
So maybe it will be possible to travel a bit into the future under extraordinary circumstances, but to travel BACK in time - heck, thats not possible. That would be like reversing the fabric of space itself. Very destructive.

I know what you're trying to say, but I disagree. You're trying to define exactly what the term "time Travel" means, which I don't think it's something that we can define and especially not based on our observations of what science fiction has shown us (projected instantly). Trying to say that I would just be frozen is just a observation from YOUR perspective from outside the train, who's to say that YOUR time is the real time and that you can make that observation. To me, MY time is what is relative and in my time I end up a hundred years in the future after a week long train ride. I wasn't frozen as you said and nor did I slow down in my perspective, only yours. I think this is exactly what "time travel" means, you traveled from one point to another point in time (your time) 100 years in the future. You traveled through time....who cares how you did it.
Although I think it's hard to really define what time travel is for us because we aren't anywhere near being able to do it, here are the definitions that are out there:
Encyclopedia of Philosophy
An object time travels if and only if the difference between its departure and arrival times as measured in the surrounding world does not equal the duration of the journey undergone by the object.
Wikipedia:
Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space, either sending objects (or in some cases just information) backwards in time to some moment before the present, or sending objects forward from the present to the future without the need to experience the intervening period (at least not at the normal rate).
This stands up to any definition...

Oh....and no, the train is actually whizzing past you're face at the speed of LIGHT!!!! Nothing slowed down by you're perspective at all!

apparently time travelling was happening already in 2004.
