There are those who deny Neil Armstrong walked on the moon and keep the story was a government conspiracy. The idea that a man could actually break away from the cradle of our atmosphere and gravity was once fiction of the highest kind. Another dreamer made it a reality. What is it to believe about space travel? Will it be when this is feasible?
If space travel has to travel at light speed, the situation is not promising. The biggest obstacles to such travel are g-forces and time. G-forces are force exerted on the body when undergoing high acceleration. The speed of the speed of light would be done gradually or body was torn apart. It would take about 2 ½ months to get only half the speed of light! This explains the need for the inertial dampers-Cosmic shock absorbers equipped with Star Trek writers. Inertial dampers somehow cancel out the force respond to the growing value. While this solves the problem for writers, there is no such tool in the real world physics.
Which takes us to the problem of time in space travel. Theoretically, two things happen when things travel at the speed of light. First, the time will be relative and “right” for objects in motion. A ten-year journey of Star Craft would equal 25,000 Earth years-making any communication impossible. In addition to this, things get heavier the faster they travel. When approaching the speed of light, they become infinitely heavy, which is why only massless objects, like waves can travel at such a speed
The space travel at light speed or faster is probably not feasible. However, space travel could still become a reality. Imagine that you are a microscopic mite on a flat piece of paper. The world appears to be flat, and indeed any attempts on the local environment website would lead you to that conclusion. If your world was flat, the fastest way to get from your position to a point at the end of this page would be a straight line. However, if the site was turning, and you could drill a hole through your site, you would find a shortcut. This is the idea behind wormholes. Unfortunately, geometric equations show wormholes be impossibly unstable.
Before they could be used as a viable bridges to new star systems or galaxies, one would find a way to keep them from pinch of instant speck of matter into her throat. Still, wormholes our greatest hope for space travel. Although wormholes are still only hypothetical (there is no experimental evidence for them), they are great fun theoretical and applied solutions of Einstein equations. It is no wonder they are a topic of interest among scientists and science fiction writers alike.
