Why People Doubt That Space Travel Is Possible

Interstellar space travel isn’t impossible and how to understand why people believe it’s impossible lets you know what problems to solve. One of the main things considered is light speed and the impossibility of achieving it. The first thing to understand is that we don’t have to go light speed to get to the next star system beyond our solar system. 10 percent – 15 percent of light speed is all that’s needed and this can be accomplished. So the first problem is solved. This doesn’t make a star to star travel any easier of course. Another reason people think interstellar travel is impossible is that it seems to be too complex. It’s, in fact, simple and no more complex than interplanetary travel. This problem is solved.

What is required for space travel?

Humans want to go 30 percent – 98 percent of light speed which is simply not achievable at today’s mechanical sophistication level (MSL). The energy requirements are off the scale to accelerate anything to such a speed. This is not to say we can’t produce this amount of energy on the Earth’s surface. As an example: to accelerate a 1-kilogram mass (2.2 pounds) to 25,000 miles per second (14 percent of light speed) takes 800 megawatts of power. To put this much hardware into space to produce that much energy is meaningless.

When dealing with a star to star travel you must deal with physics, humans, and money. To journey at light speed can be imagined in a movie but physics will not allow it as a reality. When humans consider star travel they imagine using thousands of kilograms of mass and it’s simply not possible to accelerate this much mass to 10 percent – 15 percent of light speed. Much less mass on the order of milligrams must be used and this problem is solved. The third problem is sending a human being. A human weighing 220 pounds or 100 kilograms would take all the energy humans to produce on this Earth in a year to accelerate it to 2 percent of light speed. This means it won’t be happening anytime soon. Don’t send humans and this problem is solved.

Ten to fifteen percent of light speed is 18,600 miles per second to 27,930 miles per second respectively. These aren’t trivial speeds. The fastest speed achieved to date in outer space is 71 miles per second for only a few dozen seconds. How much did such a project cost to achieve? $100,000,000 or more? Putting anything into outer space costs money and a great deal of it. The cost of an interstellar project must be kept under $600,000,000 and not billions of dollars. The problem of an interstellar project’s cost is solved.

‘A’ for an effort

There’s a great deal of innovation taking place to solve this matter of star travel and humans have been active for at least 65 doing so. Humans have considered everything real and imaginary to get the job done. Humans must be given an ‘A’ for effort, inventiveness, ingenuity, creativity and never give up. Star travel is possible of course because all you need is the method and the money to do it. There are 9 problems that have been presented but these 9 problems can be reduced to 4 and they are easy to solve and in this way proving that star travel is very much possible.
