Space travel-science or fiction?

There are those who deny that Neil Armstrong walked on the Moon and maintain that the whole story was a government conspiracy. The idea that man might actually detach from our cradle of atmosphere and gravity was fiction like higher. Still a dreamer has made it a reality. What's not to believe about space travel? There will be a time when such a thing is doable?
If interstellar travel requires travel at light speed, the situation is not promising. The biggest barriers against such trips are g-forces and time. G-force is the force exerted on your body when subjected to high accelerations. Accelerate the speed of light would have to be done gradually and body would be ripped apart. It would take about 2 months and get only half the speed of light! This explains the necessity of inertial dampers, the cosmic shock created by writers of Star Trek. Inertial dampers cancel somehow the strength to respond to the accelerating force. While this solves the problem for writers, there is none of these tools in the real world of physics.
That brings us to the problem of time in space travel. Theoretically, two things happen when objects traveling at the speed of light. First, the weather becomes relative and "slow down" for moving objects. A journey of ten years on a craft star corresponds to Earth 25,000 years-do any communication impossible. In addition to this, get heavier objects travelling faster. When approaching the speed of light become infinitely heavy, why only massless objects, like waves, can travel at that speed.
Therefore, space travel at the speed of light or faster is probably not feasible; However, space travel could still become a reality. Imagine that being a microscopic mite on a flat piece of paper. The world seems to be flat; and indeed, all trials on your immediate environment would lead to that conclusion. If the world was flat, the fastest way to get the position of a point at the opposite end of the page would be a straight line. However, if the page was to bend, and you could drill a hole through the page, you should find a shortcut. This is the idea behind wormholes. Unfortunately, geometric equations Show wormholes to be incredibly unstable.
Before they could be used as vital bridges to new star systems or galaxies, one would have to find a way to keep them by pinching off the moment a speck of matter entered the Gorge. Wormholes are still our greatest hope for space travel. While wormholes are still only hypothetical (there is experimental evidence for them), are great fun and theoretical solutions of Einstein's equations. Not surprisingly, are a topic of interest among scientists and writers of science fiction in the same way.
