Oh for pities sake. A nice drive around Tenerife and you've still not figured it out.

Myself included, we often assume the universe is static. If this were the case the universe would be flooded with light.

Space does not need to expand faster than light travels, it took nearly 200 years for humans to understand this.

Imagine travelling on the road a 100 miles to you destination. After the first mile travelled you've got 199 miles to go, 2 miles into the journey you find you've got 298 miles to go and so on.

This is what is happening to the photons that finally make it to us and why the visibility of the edge of space as we know it is limited.

Common sense tells me this "flooded with light" business is bollocks. I see the light from distant stars as functioning similarly to light from a torch a mile away. I can see the torch shining from that distance (therefore the light has reached me BTW) but it is ineffective at illuminating the place I am standing as it is so dispersed.

because light rays need to bounce off something to be visible

So it's possible that our sun is in fact the only star in the universe, and all the others are just reflective planets.

Hubble isn't seeing into the past from the point of the big bang but into the past from how far our sun's light has reached.

Indeed not. Time is an illusion and tea time is doubly so.

Lunchtime Shirley?

[Zoiderman]

during my key stage 3 science lesson i also asked my teacher at the time, if sun illuminates the earth why is space dark? simple answer came back, because light rays need to bounce off something to be visible

maybe i've misunderstood the question but isn't that still the case?

He probably lied to him/her

Then the light would reach us! (eventually)

Aye AB

In fact you are correct in a way - your earlier point regarding the Universe expanding faster thatn the speed of light is true - if Big Bang theory is correct - that in the milliseconds followng the First Light - the Universe did expand faster than the speed of light - some Cosmologsts atribute this to that during the those frst milli-seconds the nomal Laws did not apply.

And of course if the data from Planck confirms that the MulitVerse theory is correct than Big Bng theory in turn is obsolete - well -we should all sit down and have a good cup ot tea.

So it goes.

The Time that can be deescribed is not the True Time - nor even Tea Time.

There is no 'true' time, everyone's clock ticks at a different pace.

[AlfredJPruffock]

Time is what it's defined to be.

No.

[scooterscot]

That would mean the Universe is expanding faster than the speed of light!

No.

[Arturo Bassick]

Simply put the accelerating expansion of the universe prevents distant light from ever reaching us.

[scooterscot]

While musing the +/- of solar panels I began to wonder why the universe appears dark if there are so many stars in it. :roll eyes:

Look I'm on holiday,

It's taken humans nearly 200 years to answer the question, why is the sky dark? And it's not until very recently (the last 20 years or so) we've understood why.

It is. It's called background radiation, at about 3K.

At my local GP's practice, I always have a choice of two. And I never know which to see. It's a real pair o' docs.

I believe this is your coat?

[NotAllThere]

He didn't know about the big bang but was right in that there are stars whose light will never reach us.

But in an inflationary universe, light is also red shifted, in effect the sky could be filled with stars whose light is dimmed.
