Vega is relatively close at 25 light years. At one tenth of the speed of light, it would still take 250 years to reach it from our solar system.
The energy required for a spaceship to travel at 90 percent of the speed of light would be substantial due to the relativistic increase in kinetic energy as speed approaches the speed of light. The energy required can be calculated using Einstein's mass-energy equivalence formula, E=mc^2. The exact amount of energy would depend on the mass of the spaceship and would be calculated as the difference in energy between its rest mass and its kinetic energy at that speed.
Traveling to Gliese 581c, which is 20.3 light-years away, would take several decades or even centuries with current technology. The exact time will depend on the speed of the spaceship and advancements in propulsion systems in the future.
There is no known way to achieve this, as well as a great deal of consistent and convincing work in Physics over the past 100 years or so that says it's fundamentally impossible.
Between 100,000 and 180000 years.

That depends on how fast your spaceship can travel, and what kind of a route you follow.Spacecraft never travel in straight lines. But if you could do that, and if you kicked it up to,let's say, a million miles an hour, then you'd pass the moon in 14 minutes (it took the Apollomissions 3 days), and you'd be at Vega in only 16,970 years !
If a spaceship were to travel close to the speed of light as it passed by us, it would challenge our current understanding of space travel and exploration. The effects of time dilation and length contraction at such high speeds would need to be considered, potentially leading to new insights and advancements in our ability to explore the universe.
If you could travel faster than light, then you could also travel to the past. This is related to the definition of simultaneity, in the Special Theory of Relativity.If you could travel faster than light, then you could also travel to the past.

The part about the spaceship going with the speed of light is not real. I don't understand the earlier part of the question.
Light speed is over one billion kilometers per hour. Not only can a human not run that fast, no spaceship can ever travel that fast, at least according to the laws of physics as we currently understand them.
You could try becoming a ray of light.
because you have to go faster than the speed of light to travel in space and since light is the fastest thing in the universe, you are technically going back in time
The answer is neither.
a spaceship. Or the light. I think that is the fastest thing.
No, the laser beam would never reach the other spaceship because the speed of light is constant and finite. As the two spaceships are moving away from each other at speeds close to the speed of light, the distance between them would be increasing faster than the laser beam could travel.
Light could travel seven and a half times around the world in one second.
