Astronomy or Paleontology

or do you like T-rex, sauropods, triceraptos. and other great dinosaurs

i am torn, i love both, i believe space is cool but i also find dinosaurs to be the most amazing creatures who have walked the earth, they rock my world and is more awesome then humans 

when will they make a telescope to look 65 million years back in time  , or 100 million years back in time.

and is the ting they do in Jurassic Park possible or impossible or plausible

Think about this: when you look at a star 65 million light-years away, you see it how it was 65 million years ago. Conversely, if you were on that star you would see the Earth how it was 65 million years ago.

Now, think that we go there and place a huge mirror orbiting the star and facing to the Earth. When you look again at the star, in the mirror you will see the Earth how it was 65 million years ago.

EDIT: sorry, you will see the Earth how it was 130 million years ago, the time it took for Earth's light to reach the mirror and back.

Now, of course for that to happen, even if we could place the mirror there tomorrow, it would only be our descendants 65 million years from now (edit: 130 million years) that would be able to see us now in the mirror  maybe leaving them a video recording is cheaper than placing that mirror

First, finding such old DNA well enough preserved is basically impossible, but the theoretical principles behind the story are valid and currently DNA of endangered species is being kept so that in case of total extinction the species can be hopefully recovered by cloning.

Two considerations are: the DNA must be inserted on a parent animal and it seems clear that only genetically similar animals can develop the embryo in a viable way, so for example, an extinct sort of goat (the Pyrenean Ibex) whose DNA had been preserved was cloned using a normal goat as mother (although the calf died shortly), but we do not have any current species which could likely develop an embryo with dinosaur DNA. 

Secondly, one specimen DNA does not solve much, you need at least a male and a female's DNA if you want to recover the species, otherwise you will just clone one animal which will eventually die. And even with just one male and a female, it's doubtful that there would be enough genetic diversity to produce a viable lineage. It is highly likely that you need to have perfectly preserved DNA of a few males and a few females (and some similar species to act as first mother) to start anything like Jurassic Park.
