Exactly. All we see is inside a bubble.
Is there any way they can calculate where inside the bubble in relation to earth was the place where the universe first exploded into being?
Th universe has an age. The sun has age. they are not the same. We have background noise from the creation of the universe and we can look into deep space. And we can see the red shift of galaxies. We know the timing for the creation of the various elements of the periodic table and under what circumstances they were created.
Is that enough information to determine in which direction and at what distance the universe was first formed when telescopes look out from Earth?
