If time travel was ever possible, how come we dont have visitors and messages?
Oh yes, there will be those that say "how do you know we havnt" and claim that some group such as the Illuminati or presidential club can control everything, including Alien contact but I dont go in to that. No not even the Hipster Time Traveller convinces me.
If Scientists at CERN discovered it, or if future scientists in a future CERN discovered it, they would probably contact Scientists back here, not secret societies that control the earth.
However, if you contact someone like say a Scientist and they change something because of that, say they invent time travel sooner, and that means that the contact you got from the future Scientist doesnt happen in the future but it has already happened in the past, and considering you cannot unlearn something, would you break the space time continuum?

In programing (extreme novice) loops that are not ended eventually crash the system. Although its believed space is infinite maybe it isn't.......

I believe that "when" the time travel "mechanism" was/is discovered is the start point in the time line. Operators any time PAST the discovery point can do what they do by going back in time and foward, but before the discovery point, nobody can travel back or foward because the time of discovery mechanism hasn't been found yet.
So, we may be visited by time travelers, or not. The main question is whether or not we currently have an operational mechanism, if not, we're going to have to wait until it's produced, if we live that long to that point. Otherwise we get to sit back and hope we run into a time traveler.

... Only if you ascribe time as a dimension. Euclidean or "Einsteinian"? Dimensions were described mathematically as physical dimensions, not temporal. So the first 3 are physical, then the fourth a divergence to the non-physical, cheap yet succinct... Hmmm.
Yes definitely food for thought, but I don't think our flesh and blood bodies will survive where there is no Time.

Just some food for thought...
Not really a question as such...
No time = no entropy, hence a reality/dimension without time would be viewed from our perspective as 'afterlife', 'heaven', 'eternity'....
its hard to put into words so im sorry if this doesnt help much.

What is your definition of 'space'?

Personally I think that sending transmissions back in time is possible and that it is probably going to happen in the next few years or so if it hasn't already happened.
Back in the 80s as a child I had an odd experience. I was watching a movie which was one of those Indiana Jones style films such as 'Romancing the Stone' or 'King Solomans Mines' on ITV, probably late 80s and early in the afternoon. When the adverts came on one of the adverts (the Peugeot 405 one with the burning corn field and the 'take my breath away' song) was interrupted by some strange interference and then a message from around 2015ish.
The voice was slightly garbled, but it was saying that it was the first experiment in sending transmissions back from the future. The visiual transmission was also like nothing I had ever seen. The graphics were more like something you would only get in more recent times with high end computers like a high spec PC or Xbox. The visual was like a camera angle flying through a tunnel with advertisements for several familiar and unfamiliar companies including, but not limited banks. This transmission only lasted for around 30 seconds and then disappeared again with some static in time for the end of the advert that it has interrupted.
Now of course this may be simply the product of an over active imagination or a dream, but I doubt that. The memory exists and feels vivid and real. Make of that what you will, but I am pretty sure that I am not mental or making this up.
