Isa 40:22
22 It is he that sitteth upon the circle of the earth, and the inhabitants thereof are as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in:
Zech 12:1
1 The burden of the word of the LORD for Israel, saith the LORD, which stretcheth forth the heavens, and layeth the foundation of the earth, and formeth the spirit of man within him.
Strong claims that seem to be consistant with what would be required for it to be truth.
I figure if God has the capability to create a universe, and hurl galaxies at 500,000 miles per hour, He has the ability to stretch light across the universe so that it is seen everywhere from the start of Time.
Isa 40:12-15
12 Who has measured the waters in the hollow of his hand,
or with the breadth of his hand marked off the heavens?
Who has held the dust of the earth in a basket,
or weighed the mountains on the scales
and the hills in a balance?
13 Who has understood the mind of the LORD,
or instructed him as his counselor?
14 Whom did the LORD consult to enlighten him,
and who taught him the right way?
Who was it that taught him knowledge
or showed him the path of understanding?
15 Surely the nations are like a drop in a bucket;
they are regarded as dust on the scales;
he weighs the islands as though they were fine dust.
