Space travel-science or fiction?

There are those who walk on the Moon Neil Armstrong to claim and rejects the whole story was a government conspiracy. Defeating the humans from the cradle of our atmosphere and gravity actually thought that kind of best novels were once. Still one dream we realized it. What about space travel, or don't believe. It is achievable or not.

If you need to move at the speed of light in interstellar travel is not promising situation. G-forces and time is the biggest hurdle against such travel. G force with force when subjected to high acceleration your body. The acceleration will be done gradually to the speed of light or body torn apart. It nearly two months and a half, to get only half the speed of light! Describes the necessity of the shock absorbers were created by the writers of the inertial dampers, the universe of Star Trek. Ability to respond to the accelerating force somehow cancels inertia dampers. To resolve the problem for script writers in the world of physics don't really like this tool.

US space travel takes a matter of time. Two things happen when you move the object at the speed of light is theoretically. Becomes relative to the first "in-motion objects drop". Star craft, all communication impossible in the 10-year journey to 25,000 corresponds to Earth. In addition, objects, high speed travel heavily. Can travel in waves when approaching the speed of light is massless objects only such speed therefore becomes an endless heavy.

Therefore the space at the speed of light moving or faster feasible will not; but space travel could yet become reality. Imagine the microscopic mites, flat piece of paper. Your world is flat would seem; indeed, all the experiments in your immediate environment has come to the conclusion. If your world was flat, get at the other end of the page from your position, the fastest way is straight. In a bend of the page, however, you can pierce through the pages and find shortcuts, no pointless. This is the thinking behind the wormhole. Unfortunately, geometric equations wormhole extreme volatility in the shows.

You must find the input method before it can be used as a viable bridge new ???_???? and galaxies one speck of throat problem moments from pinching off to keep them. Yet the wormhole is space travel for our greatest hope. The wormhole (experimental evidence for them is not) still only hypotheses are they fun theory of Einstein equations valid solution is. Is it no wonder interest scientists and sf writer.
