Do you wish you could travel at the speed of light?
Ever wish you could travel at the speed of light to your favorite destinations? Once you see the reality of that speed, you may rethink everything. “There are some important things you should probably know about approaching the speed of light,” NASA’s new video, Guide to Near-light-speed Travel, explains.
How does the speed of travel affect the way we see?
Its equations show that objects look increasingly distorted as the speed of travel increases, with the view ahead becoming progressively brighter. Then truly bizarre effects start to kick in, with objects far ahead apparently moving further away, while those behind come into view.
What happens to time when you move with the speed of light?
So for someone standing still and watching you move with the speed of light will see your moving really fast in time (as in reaching from point A to point B really fast) but you yourself will experience the time at the same rate. Length contraction [ 3] is the most interesting part of this experiment.
Do you need shields at the speed of light?
So you should probably have shields that keep them from frying your ship and also you.” Finally, the video tackles the fact that even if you were moving at the speed of light, the “universe is also a very big place, so you might be in for some surprises.”
How long would it take to travel to the farthest galaxy?
A trip to the Andromeda Galaxy, our nearest large neighbor galaxy, can take over one million years. And a trip to the farthest known galaxy where it currently sits might take over 15 billion years, which is more vacation time than I think I’ll ever have.” The video doesn’t explain how your rocket will travel at the speed of light.
Why is the speed of light constant in free space?
• The speed of light in free space has the same measured value for all observers, regardless of the motion of the source or the motion of the observer; that is, the speed of light is a constant. © 2010 Pearson Education, Inc. Simultaneity • We say that two events are simultaneous if they occur at the same time.
How long does it take to get to the edge of space?
For example, your rocket’s clock will say it takes about 9 months to get from Earth to the edge of the solar system. An Earth clock would say it took about a year and a half. “If you want to get to farther out vacation spots,” the video explains, “you’ll probably need more than a few extra snacks.
