From our perspectives, we observe that the Universe is expanding; the galaxies are moving farther away from us; they are being red-shifted. But it might be possible, that the Universe is not actually expanding, it's contracting towards the very same singularity it took place almost 13.8 billion years ago. This would eventually create another Universe. That's exactly what is accelerating our universe's expansion; the dark energy is nothing but the force of the singularity, where all the mass of the whole Universe lies. And this contraction would not be just 3 dimensional; it is happening in the 4th dimension; universe is expanding to it's past singularity (contraction). Just thougts.
Mr Rana,
>But it might be possible, that the Universe is not actually expanding,
Can you offer any evidence for this notion?
Standard candles of various types are fainter in galaxies with higher redshifts.
Your notion appears to fly in the face of known evidence - well, evidence that I know of.
James Garry I agree with you. But at the same time, It may be possible that what we believe is going away from us might imply that its going towards the singularity which he talked about. It might have to do something with frame of reference from which we are observing this redshift/blueshift.
