# Is the Internet as fast as the speed of light?

No, the internet you have is conveyed via radiation, of which the speed is equal to the speed of light, or through wires by moving electrons, whose drift velocity is less than the speed of light. According to special relativity mass tends to infinity at light speed.

### Can anything travel faster than the speed of light?

There is no limit to how fast the universe can expand, says physicist Charles Bennett of Johns Hopkins University. Einstein's theory that nothing can travel faster than the speed of light in a vacuum still holds true, because space itself is stretching, and space is nothing.
• #### What is the fastest thing in the universe?

Blazing Speed: The Fastest Stuff in the Universe. A sequence of radio observations shows a plasma blob moving away from a blazar's core (right) over about 8.4 months. SAN DIEGO -- If you're light, it's fairly easy to travel at your own speed -- that is to say 186,282 miles per second or 299,800 kilometers per second.
• #### What would happen if you could travel at the speed of light?

As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.
• #### What is the speed of electricity?

Therefore, the speed of electricity in a 12-gauge copper wire is 299,792,458 meters per second x 0.951 or 285,102,627 meters per second. This is about 280,000,000 meters per second which is not very much different from the speed of electromagnetic waves (light) in vacuum.

### What is the speed of light in simple terms?

Physicists often use the letter c to denote the speed of light in empty space (vacuum). It has the value 299,792,458 meters per second (or about 186,282.397 miles per second).

• #### What is the value for the speed of light?

The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is299,792,458 metres per second (approximately 300,000 km/s (186,000 mi/s)).
• #### What is the formula for the speed of light?

Formula: c = f where: c = the speed of light = 300,000 km/s or 3.0 x 108 m/s. = the wavelength of light, usually measured in meters or Ångströms (1 Å = 10-10 m) f = the frequency at which light waves pass by, measured in units of per seconds (1/s).

### What is the definition of the speed of light?

Definition of speed of light. : a fundamental physical constant that is the speed at which electromagnetic radiation propagates in a vacuum and that has a value fixed by international convention of 299,792,458 meters per second —symbol c.
• #### Can you travel at the speed of light?

If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light. That answers our question, but let's have a little fun on the next page and modify the question slightly.
• #### What is the speed of light in a year?

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.
• #### What is the speed of light GCSE?

We know light covers a distance of 300 million metres in one second (speed of light in a vacuum is 3 x 108 m/s) so in one year it will cover a distance of 9.46 x 1015 metres. One light year is the equivalent distance light travels in one year.
