Nothing can travell faster than light ?? but.......?

but that's because of relativity theory . it needs infinite energy . okay then it should be a ' thing ' with mass (mc^2) but the space is virtually 'nothing' n as space is also an entity formed from the big bang . 'new space' is continously being created n putting all the galaxy far away . then 'new space' travels faster than light isn't it ? that is formation of 'new space' means expansion of universe(THE 'NOTHINGH' HAS SPEED) . and it travels faster than light isn't it? because if it wasn't going travell faster than light then the farthest known object (star) should be 12 billion light years away in a universe known to be 13 billion years old. that means this universe would be fully lited like tube light . coz it had enough time to travell . the light from all the stars everywhere would have traveled along with space(if it wasn't faster than light) and filled it with blaze of light . but at present we dont see that in the sky .the universe expands faster than light ????

You have it. We call what we can see the Observable universe, because the part beyond what we can see is receding at greater than light speed. If the universes expansion is speeding up, then the light from farthest galaxies we can see will soon be red shifted into oblivion. Those galaxies will be moving away from us at greater than the speed of light.


If you came up with this concept by yourself, you have one heck of a career as an astrophysicist ahead.
Reply:YOU CAN GO FASTER THAN THE SPEED OF LIGHT, NIKOLA TESLA DEMONSTRATED THIS TO US 100 YRS AGO. when pulsing the earth with energy he found that the pulse left and returned faster than the speed of light(teslas was 471,240 km/sec, light is only about 300,000 km/sec)einstein is wrong Report It

Reply:You are right about the big bang and space being created continually.


The universe is a finite entity so it has a maximum size.


The farthest objects you see are not in existence any more.


The original state that created space could have stopped and the universe is in a state of decline


The universe may not be more than 7 billion light years in diameter but it may be much older than 7 billion years.


Galaxies are probably the end stage in the evolution of the universe.


The red shift is an artifact of the evolving galaxies giving a false impression about the size of the universe.


The universe can only expand within the limits of it's maximum size,so it cannot be in an accelerated expansion.
Reply:You're having a little trouble articulating it but you are basically correct. Nothing within the so-called "metric" of spacetime can travel faster than light, but the metric itself -- that is, the structure of spacetime -- has no such restriction, and can expand arbitrarily fast. In fact, that is the basis of what is called the "inflationary model" of the Big Bang. It states that very shortly after the Big Bang, spacetime expanded very suddenly at a rate much, much greater than the speed of light.





We see direct evidence of this. When looking at distant supernovae whose instrinsic brightness is known, we are able to determine that the expansion of the universe is accelerating. The light that has traveled 13 billion years to reach us comes from a distance of some 42 billion light years away... not 13 billion. See http://www.astro.ucla.edu/~wright/cosmol... for a tutorial about this.
Reply:Light can travel faster than light. Sounds like a great oxymoron but it isn't. To better explain this Einstein and others have worked on explaining it in relativity. View space as time and vice versa. Now realize you can Bend space and you can bend time. You can have 'thick space' you can have thin space. so light traveling in thick space would appear to be slower than light traveling in thin space. so if ya shot a beam of light from 2 equal distances and shot one from an oblique angle from a super massive object it would strike the object first but yet travel a greater distance. Geodetict effect.
Reply:well your question just proved the big bang therory is wrong . i still think god made all the heavens and earth within a weeks time
Reply:Despite your poor grammar, you have put your finger on a fundamental question.


But there is no way to tell how a cubic meter of vacuum travels through a vacuum.


Even light, which should grip onto this three dimensional fabric of space does not.


This was shown in 1887 by the Michelson/Morley experiment.


It took Einstein to properly explain it.


That is what relativity is all about; but you have to learn classical physics before you can begin to appreciate some of the implications of this.
Reply:Your theory falls short due one fallacy: If you conjecture that the Big Bang began to create space, into which objects can now move, what do you think was there before the Big Bang? Before the space existed? If it wasn't space (or nothing) then it had to be SOMETHING, right? So the Big Bang began erasing the SOMETHING that was there to allow the space to exist into which all the stars %26amp; planets may now move?





Emptiness must always exist in order for something to be placed there. You can't have something there, and nothing replaces it. That's silly.





I'm going to lunch now.
