  1. You have to account for the expansion of space; this effect wasn't accounted for in the previous examples since it's negligible on those scales.

     

     

    What does that mean????

  2. I know what Gilded meant i was pointing out that it wouldn't take around 8min for us to know that the sun was expanding into a red giant, since it is coming closer to earth every second. and it would take less than 8min.

     

    To another point if theoretically if we find a planet that's 13.7 billion light years away would we see the creation of the universe????

  3. yes, Gilded thnx for the answer,but if the sun did explode it will be heading for us but is wouldn't take 8 min for us to know, since it is coming closer to US!!!

     

    RIGHT??????

  4. Is it true when you look at a star/planet/black hole...anything that is light years away that when we look at it when it was anytime before?

     

    e.g. Say there is a planet 2 light yrs away, then we invent a telescope and look at the planet, we would then be looking at the planet 2 yrs ago. So when we look at the technically the light is lagging?

  5. If someone drilled a hole right through the centre of the earth (supposing there was no heat, compression, magma).

     

    AND THEN YOU WALKED RIGHT INTO THE HOLE, WHAT WOULD HAPPEN
