If we take the most distant quasars and galaxies from as in all directions we get a sphere of radius 13,7 billion light years. As we know they were there 13,7 billion years ago.This suggests the following: at the beginning (call it big bang) there was a sphere of 13,7 billion light years instead of a small point.Is this right?

1That's not the radius of our observable universe FYI. https://en.wikipedia.org/wiki/Observable_universe#Misconceptions_about_its_size – JMac Jan 30 '20 at 19:11

1It is not clear to me what you are asking. Putting 4 question marks at the end of your post does not make it into a question. – sammy gerbil Jan 30 '20 at 22:58

What Sammy said. You need to ask a clear question, or this question will get closed. I posted those links earlier in the hope that they'd help to clarify your misconceptions, and to prompt you to ask a focused question. – PM 2Ring Jan 31 '20 at 06:17
