Speed of light – Distance light travels – How light behaves in space.

I have mentioned that some calculations are made by our scientist from theories, and as we all would like to go back to the past, they seem to think that by studying and reaching the source of the images the Hubble telescope sends us, they will be able to do that.

They think the light reflections that Hubble captures, of dieing stars and new constellations being formed have taken place billions of years ago and because they take their calculations from the theory that these images have travelled at the speed of light to reach Hubble, and the distance covered by the light source would take so many light years to reach it, then the images must be billions of years old, which in turn will give them an insight to the origins of the universe.

We know how man made electric light functions, but we have to ask if terrestrial light functions in the same way.

Electric light only travels so far and the farther out it goes the broader it becomes, weakening its strength.

An example of this is street lights that are positioned at certain distances apart so that each lamps beam connects with the other to light up the street. If the light did not weaken then we would only need one lamp to illuminate the whole street, or even further if it was unobstructed, like the images captured in space by Hubble.

Another example of light weakening and broadening is when a lighthouse‘s beam is observed by a sailor over the open sea. It is clear to see the beam as it swings round, just how much it widens the further away it gets from its source, also how much weaker the beam becomes as it widens, but it is also noticeable that the light only travels so far, hence the different strengths of lights for the given situations.

Laser light on the other hand is an intense narrow beam as it is amplified, stimulated by the emission of photons from excited atoms or molecules, which makes it behave in a different way to basic electric light, allowing it to travel great distances, but AS electric light, it is still man made.

Terrestrial light, like our sun is natural, and being a natural light source it behaves in the same way as man made electric light, weakening as it projects out into space, and as the beam widens it also limits the distance the rays travel.

If you think of all the stars and light sources out there in space, and take into consideration the power produced by them, heading towards earth, then the light and heat radiated by them, if not weakened, would be so intense, creating dazzling daylight twenty four hours a day, that we could not survive anywhere in the universe, let alone this planet.

That is why we cannot go back to the past by studying the images sent by Hubble,because these occurrences that are being captured out there are happening NOW, not something that happened billions of years ago.

It is us that is reaching out to the light source through Hubble NOT the light source reaching us, like the sailor approaching the lighthouse, the beam becomes stronger and clearer as he nears it, but it is the same source that was seen faintly on the horizon, and if an object came between them, the light hitting the object would be obscured immediately leaving a shadow resembling that particular object, reappearing immediately the object was removed, or if the object was big enough or close enough to the light source it would obscure the light altogether. That is one example of my theory, and although the distances between a lighthouse beam and terrestrial rays are vastly different  in comparison, the end result is the same.

If we had the means to travel to that light source where a star is dieing or a constellation is being formed then we would be able to see the exact same thing is happening at the source, as is happening in Hubble’s images. How can you possibly reach the outer beam, then travel through it to a void left after the star died, or to the reaction in space that created the new constellation you were now travelling through? The source of the light  still has to be there to power the beam or ray’s projection, on the same principle as a movie camera projecting an image onto a screen. When the camera is switched off the picture disappears, and when the star dies, projected images of its life dies with it, and does not leave a record of its past on some screen in space.

Sound on the other hand is different. If you switch the source of the sound off, the noise will carry on, echoing through the air waves until it too becomes so weak that it fades out. Perhaps that is why our scientist think that light carries on once the source has been switch off, but given the experiments they do, they should have realised by now that, that is not the case, and forget trying to reach the past by these unlikely means.

They will discover something new in space every day if they look hard enough and in the right place , and perhaps they might discover the origins of the universe, but it will not be at the end of a light beam.

The past is in the past and the only way we can find out about it is by excavating the remains of it, be it on earth or out there in space, the latter being well out of our reach. Even with the excavations on earth we still have to guess and surmise the origins of the human race, with our ideas having to be altered regularly as disturbances to the earth’s crust uncovers new sources and artifacts for man to investigate.

How can we possibly think that we can discover the origins of the universe from earth when we are still struggling to decipher the discoveries on our own planet?

My conclusion is, that, even out in the deepest of space the past is the past, and has gone, with no way of going back to it, not even if we can find a way to reach the light sources the scientist think will take us there, so they will have to have a rethink, just like the archaeologists who excavate and theorise on our past until new discoveries and realizations are made.

The universe travels onward and outward, and the only going back will be when it stops, and the gravitational pull of the immense planet at the core of it all drags everything back, but time will still be carrying forward with new events taking place, and the old ones, though not  forgotten………………………… in the past where they will stay, regardless of mans ambition to return there.
