Cosmic Adventure 3.9-10 World of Finite Light Speed

The world of finite light speed is totally different from that of infinite speed. It is time and space layered caused by the delay in image delivery.

  2. 2. © ABCC Australia 2015 new-physics.com An Object Emits or Reflects Light Every object in this universe either emits or reflects light.
  3. 3. © ABCC Australia 2015 new-physics.com Light & Vision We can see an object because its light brings the images to our eyes. Light is the visual image carrier in our lives.
  4. 4. © ABCC Australia 2015 new-physics.com Our eyes intercept the light and interpret them as the images in our mind. This is the way how we can see.
  5. 5. © ABCC Australia 2015 new-physics.com Image Carriers In such a way, light is serving as the carrier of images, bringing us the enjoyment of vision.
  6. 6. © ABCC Australia 2015 new-physics.com Speed of Light too Fast Light travels at a speed of about 300,000,000 meters per second. This is an astronomical figure. There is nothing in our daily life that comes anywhere near to it. For example, the speed of sound is only 343.2 meters per second; even supersonic speeds of 5 or six times greater than the speed of sound are only about 1,500 meters per second.
  7. 7. © ABCC Australia 2015 new-physics.com Light too fast to be Detected In ordinary life, light is so fast that this delay is not perceptible. To cover a distance of one meter, light only takes about 3 × 10−9 second. Even in the larger scale, light takes only 1 second to circle the earth ten times. That is why when Galileo Galilee tried to measure the speed of light using crude equipment, he could not find anything.

  10. 10. © ABCC Australia 2015 new-physics.com Light Takes Time to Travel But no matter how fast light travel, it still needs time to cover a distant, no matter how small the distance is. For an object one meter away, light from it takes 3.3 nanoseconds (10-9 second to reach our eyes; for an object one kilometer away, light from it takes 3.3 microseconds to reach our eyes. (A microsecond is a unit of time equal to one millionth or 10-6 of a second.)
  11. 11. © ABCC Australia 2015 new-physics.com Delayed Vision This means that by the time light from an object reaches our eye, some length of time must have elapsed. This is the delay of image delivery. 𝑇𝑖𝑚𝑒 = ∆𝑡
  12. 12. © ABCC Australia 2015 new-physics.com In the astronomical scale, the difference is more appreciable. Take for example, the moon is 384,400 km away from the earth and the speed of light is 299,799 km per second. The time taken for its light to reach earth is: 384,400 𝑘𝑚 299,799 𝑘𝑚/𝑠𝑒𝑐𝑜𝑛𝑑 = 1.28 𝑠𝑒𝑐𝑜𝑛𝑑 About 1.28 𝑠𝑒𝑐𝑜𝑛𝑑
  13. 13. © ABCC Australia 2015 new-physics.com The light from the sun, which is about 3 × 1011 metres away, will take light to travel about 8 minutes in space before reaching earth. About 8 minutes
  14. 14. © ABCC Australia 2015 new-physics.com Another example: The galaxy of Andromeda is 2,538,000 light years away from the earth. A light year is the time taken for light to travel in one year – covering about 9 trillion kilometers (about 6 trillion miles). This is the time in years needed for its light to reach earth. 2,538,000 𝐿𝑖𝑔ℎ𝑡 𝑦𝑒𝑎𝑟𝑠
  15. 15. © ABCC Australia 2015 new-physics.com Remember how Römer discovered the speed of light due to the delay in time obvious in astronomical observation? Ole Römer Discovered the speed of Light Jupiter Io Earth moving towards Jupiter Io hides behind Jupiter and becomes invisible Earth moving away from Jupiter
  16. 16. © ABCC Australia 2015 new-physics.com Time & Distance Gap What we see are only images delivered to our eyes by light coming from a source some time ago. In general, there is always a time delay in messages which need light as a carrier, no matter how short the distance is between the observer and the observed. Observer Observed
  17. 17. © ABCC Australia 2015 new-physics.com 𝒄 So distant objects are all old ones at various time in the past.

  20. 20. © ABCC Australia 2015 new-physics.com Universe in Antiquity The proper time and place for the heavens beyond the clouds are now trillions of years away from us and their images will take trillions of years to reach our eyes. Trillion light years away Light years away Nano seconds away
  21. 21. © ABCC Australia 2015 new-physics.com Universe with Finite Light Speed Now the scenes appearing in front of us are all layered in time. The oldest scenes appear at the farthest.
  22. 22. © ABCC Australia 2015 new-physics.com Layers of Spheres Because of the finite nature of light speed, our world is actually made up of lays of time spheres
  23. 23. © ABCC Australia 2015 new-physics.com Multi-Time Universe With the idea of finite light speed confirmed, we now know that we are living in a world of multiple-time layers. That is what appears to us is a universe made up of scenes from different times. This is an universal phenomenon. It happens to to all things, everywhere in this universe, large or small.
