If speed approaches the speed of light, the mass of any object will increase. This is not just theory; it is observed on a daily basis. Not with spaceships, of course; the technology is not ready yet - but with subatomic particles in accelerators.

How much energy does it take a spaceship to travel at constant speed 90 percent of light speed?

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.


What happens to the speed of light in motor oil?

As long as the light remains in the motor oil, nothing happens to its speed.


What happens when light passes into a material where the speed of light is lower?

It moves at a slower speed!


How long would it take to reach the star Vega if a spaceship could travel at one-tenth the speed of light?

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.


What happens if you step outside of a spaceship traveling at light speed?

Well first of all, you don't. No object that has any mass when it's sitting still will ever travel at light speed. To answer your question in general: If you're sitting inside a spaceship, sipping a cup of coffee and surfing the web, and you decide to take a break from your back-breaking labor and step outside for a few minutes, then the moment you're outside, you continue traveling at the same speed and in the same direction that the ship was when you let go of it. If the ship is traveling with constant velocity ... constant speed in a straight line ... then you seem to float motionless next to it, because your speed and direction are exactly the same as the spaceship's. If the ship is accelerating, then you keep the speed and direction that you and it had when you let go, and the ship goes on its own merry way, leaving you behind, beside, or ahead.

Is man can not be growth by going in a spaceship and it is going with a velocity of light is it real or not?

The part about the spaceship going with the speed of light is not real. I don't understand the earlier part of the question.


If your in a spaceship going 90 percent the speed of light and you shine a flashlight on an onboard vacuum chamber in the same direction that the spaceship is moving how fast is the flashlight light?

I'd imagine it would go the speed of light because time would slow down to make sure the light wouldn't go faster than the speed of light.


How long will a spaceship traveling at the speed of light reach Proxima Centauri?

About 4.2 years.


How does the theory of relativity explain the effects of time dilation on a spaceship moving past us at a speed close to the speed of light?

The theory of relativity explains that as a spaceship moves closer to the speed of light, time for the people on the spaceship appears to slow down compared to those on Earth. This is known as time dilation, where time passes differently for objects in motion at high speeds.
