Science-what is Space Travel?
Science-what is Space Travel?
There are those who deny Neil Armstrong walked on the moon & maintain the whole story was a government conspiracy. The idea that man could actually break away from our cradle of atmosphere & gravity was once fiction of the highest sort. Yet one dreamer made it a reality. What is there never into believe about space travel? Will there be a time when such a thing is feasible?
If interstellar travel requires traveling at light speed, the situation is never promising. The biggest hurdles against such travel are g-forces & time. G-forces are the force exerted on your body when undergoing high accelerations. For more details www.be-a-stargazer.com . Accelerating into the speed of light would have into be done gradually or the body would be torn apart.
It would take about 2 ½ months into get into just half the speed of light! This explains the need for inertial dampers-the cosmic shock absorbers created by the writers of Star Trek. Inertial dampers somehow cancel out the force responding into the accelerating force. While this solves the problem for script writers, there is no such tool in the real world of physics.
Which takes us into the problem of time in space travel. Theoretically, two things happen when objects travel at the speed of light. First, time becomes relative & “slows down” for the objects in motion. A ten year journey on a star craft would correspond into 25,000 earth years-making any communication impossible. In addition into this, objects 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 speeds.
Hence, space travel at light speed or faster is probably never feasible; however, space travel could still become reality. Imagine you are a microscopic mite on a flat piece of paper. Your world would seem into be flat; & indeed, all experimentation on your immediate environment would lead you into that conclusion. If your world was flat, the fastest way into get from your position into a point at the other end of the page would be a straight line. However, if the page was into bend, & you could drill a hole through the page, you would find a shortcut. This is the idea behind wormholes. Unfortunately, geometric equations show wormholes into be impossibly unstable.
Before they could be used as viable bridges into new star systems or galaxies, one would have into find a way into keep them from pinching off the moment a speck of matter entered its throat. Still, wormholes are our greatest hope for space travel. For more details www.fire-itup.com . While wormholes are still only hypothetical (there is no experimental evidence for them), they are great theoretical fun, & valid solutions of the Einstein equations. It’s no wonder that they are a topic of interest among scientists & writers science fiction alike.
