I post this topic here because it is related to ufo.. Is their a real time machine? A parallel universe? How can a ufo visit in our planet? Some scientist said that it is posible only if they can build a big blackhole. Sounds crazy if they build it because anything near on it will suck by its strong gravitational field and sqeezed in the center so building of it not the best way.. I think the only way is to get the ufo or alien space craft and study thier technology. Other scientist believe that ufo is not only a spaceship but infact a timemachine!! Because travelling in space even if your spaceship travel at speed of light, it takes many years before we can reach the nearest star in our own galaxy. Einstein said that if we travel faster, time will slowed. At the speed of light, time will stop and thats the cosmic speed limit he said. But other scientist go beyond this theory, that we can possibly exceed the cosmic speed limit and if thats true we can travel back in time.. The question now arsise that what if we kill our father in the fast, this means we cannot exist in the present? The answer is the parallel universe theory that means their is a multi universe, many universe slightly different on our own universe.. That if we travel back in time, we can go in one of that universe or other dimension..

I have a time machine that I have used extensively to see into the past...

It is true if time is measured in the reference frame of the earth.
It is false if your measure time with the own clock of the travelers, and this is the most important point.
For the travelers, time t'=t*(1-v²/c²)^1/2 where t is time measured on earth. It is a well known formula from special relativity.
Imagine you want to go on Alpha Orionis at v=0.9999*c.
For an observer on earth, the travel will need around 420 years which is the distance between earth and Alpha Orionis.
For the travelers, do the math: the travel is done in about 6 years in their own time.
Of course if they return on earth, they will find it 840 years older! So such travels have to be made without the idea of coming back to see again people that we left.
The conclusion is that there is no theoretical limit for visiting all the universe. It is a false idea to believe that a travel to a star at x light-years takes at least x light-year. It can be almost instantaneous for travelers, presuming they travel at near the speed of light (at the limit, the light speed, time doesn't elapse). Thanks to Einstein.
Yah thats right it is some kind of teleportation.. But spacecraft travelling in speed of light is impossible since how can u drived your spacecraft if your time are stopped and how can you control a spacecraft with such that speed?..

Well then can you come up with next week's Lottery numbers?
Better than anyone else can, I mean?
The spacecraft you need to use is called a TARDIS.

I was (not so cleverly) referring to a t.v.....as everything one sees on it has happened in the past. Even if, in some cases, only femtoseconds ago.
lol :-\

Haha! techstuf you have some point.. Theirs no need for a timemachine, a tv may suffice to see the fast.. :o
