Time Travel:
Time travel is impossible due to the fact that time is linear, like a movie reel. If you tried to move backwards, the normal force pulling time forward would cause a rip in time, somewhere in the middle of the interval. If you were in the year 2020 and tried to go back to 2000, somewhere between 2000 and 2020 time would be destroyed. The pressure would be the greatest at the point of reentry, so the rupture would be closer to the reentry. Due to the fact that time is energy, the to end are now of opposite poles. The two poles would be pulled back together, but it would not fit perfectly. This is where the deja-voe and ESP come from. If the "film" is slightly overlapped, we see slight reflections of events, ether past or future.
Creation:
Creation is fallacy, because there is no proof that it, at some point, anything didn't exist. Because time is liner, it moves on infinitely in both directions. Hence the conservation of matter/energy, everything becomes something else
Dinosaurs:
There is no doubt that the impact of an asteroid caused the extinction of the dinosaurs, it does not mean that it did it immediately. As with any great disaster, the impact would be very importance in “history.” If some of the dinosaurs survived the initial blast, there is a slight chance they could have adapted. In fact, they may have evolved to a point beyond what man is now. If they did, they may have elected to use their advancements to go back in time and destroy the asteroid. With my above theory, this would have destroyed any time between the departure and the point of reentry, with an error of a few years.
Now this may seem very absurd, but the fact that the total extinction was quite rapid. Even if a layer of dust covered the earth, the age of fossils found around the earth would be in a cone shape. The fossils found at the site of the impact would be the oldest, and those farthest away would be the youngest.
If the cloud of dust were powerful to destroy every dinosaur, the earth would be sterile, to the point that humans could not be evolved. Even the tiniest of organisms need some light. The bottom feeders of the sea feed on those above, who feed on those above them.
Last, even if some dinosaurs survived yet did not evolve, the rate of evolution to other species would have occurred to rapidly. This might only make sense if you have heard the theory behind the bird species. Some believe that the common sparrow evolved from the T-rex, based on it bone structure.
Now, I ask you all to post your own beliefs.
Please keep this post clean and constructive.
