One famous result is something physicists call time dilationwhich describes how time runs more slowly for objects moving very rapidly.

If you flew on a rocket traveling 90 percent of light-speed, the passage of time for you would be halved. Your watch would advance only 10 minutes, while more than 20 minutes would pass for an Earthbound observer. You would also experience some strange visual consequences.

Turn Out The Light (Will Smith) - Chris K* - Need For Speed (Volume 7) (CD) such consequence is called aberrationand it refers to how your whole field of view would shrink down to a tiny, tunnel-shaped "window" out in front of your spacecraft. This happens because photons those exceedingly tiny packets of light -- even photons behind you -- appear to come in from the forward direction.

In addition, you would notice an extreme Doppler effectwhich would cause light waves from stars in front of you to crowd together, making the objects appear blue. Light waves from stars behind you would spread apart and appear red. The faster you go, the more extreme this phenomenon becomes until all visible light from stars in front of the spacecraft and stars to the rear become completely shifted out of the known visible spectrum the colors humans can see.

When these stars move out of your perceptible wavelength, they simply appear to fade to black or vanish against the background. Of course, if you want to travel faster than a speeding photon, you'll need more than the same rocket technology we've been using for decades.

Perhaps pulling on blue tights and a red cape isn't such a far-fetched idea after all. Sign up for our Newsletter! Why did it appear to travel at the same speed in all directions?

And, what can the speed of light tell us about the cosmos? It wasn't until Albert Einstein described this theory of special relativity in it all came into focus.

Einstein argued that space and time were relative and that the speed of light was the constant that connected the two. It is often stated that the speed of light is constant and that nothing can travel faster than the speed of light.

This isn't entirely accurate. The value of , meters per secondmiles per second is the speed of light in a vacuum. However, light actually slows down as it passes through different media. For instance, when it moves through glass, it slows down to about two-thirds of Turn Out The Light (Will Smith) - Chris K* - Need For Speed (Volume 7) (CD) speed in a vacuum. Even in air, which is nearly a vacuum, light slows down slightly.

As it moves through space, it encounters clouds of gas and dust, as well as gravitational fields, and those can change the speed a tiny bit.

That is why this result is so surprising and unexpected. Under special relativity, if something travels faster than the speed of light, it goes backwards in time. Such a proposition could interfere with the basic rule that cause precedes effect, called causality. In other words, it raises the prospect of time travel. There is another issue too. Einstein introduced the speed of light as a mathematical constant, c. Follow LiveScience for the latest in science news and discoveries on Twitter livescience and on Facebook.

Check the cables. If you are using an external device, such as speakers or headphones, check to make sure the cables are in good working order and connected to the proper audio port on your computer. Check the volume. If you are using external speakers or headphones that have an independent volume, make sure the volume is turned up and that the "Mute" button is not engaged.

Click Control Panel. Click Hardware and Sound. Click Adjust System Volume. Click the speaker icon to unmute any muted sounds It will have a red circle with a line next to it. Click and drag to raise the slider bar below all system sounds. Check the sound and volume settings on individual applications. Check to see if you are having volume problems on all apps, or just one specific app.

If you are experiencing volume problems on just one app, the problem may be with the sound settings for that app. For example, Spotify has a volume slider bar in the lower-right corner of the desktop app. You can also adjust the volume on YouTube videos by clicking the speaker icon and adjust the slider bar. Games may have their own sound and volume settings in the Settings or Options menu. Use a troubleshooter. Windows computers come with built-in troubleshooter app that can help you fix volume issues.

The Troubleshooter will ask you a series of questions that will help the troubleshooter determine the cause of your volume issue. It Turn Out The Light (Will Smith) - Chris K* - Need For Speed (Volume 7) (CD) also ask you to open specific settings and suggest that you make changes to the settings. Use the following steps to open the Windows troubleshooter: [2] X Research source Click on the Windows Start icon in Turn Out The Light (Will Smith) - Chris K* - Need For Speed (Volume 7) (CD) taskbar.

Type "Troubleshoot Settings".
