Astronomy questions from kids, Part 5 (last one!)
About | Information | History | Online | Facts | Discovery
My friend Tina is a teacher in Austin. She asked her sixth grade students to send me questions they had about astronomy, and I answer them on camera. There were so many I had to split this into *5* parts! This is the part. I really only answer one question: What is the Big Bang theory, and do I think it's real? But I also take a moment to talk about science, and why it's so cool.

To your second question, Space does not "grow" into anything. This might be hard to imagine but that is what drops out of the equations of general relativity and what we can see when looking at far objects in the universe. Sadly, we also know that the complete solutions of these equations would take an at least six dimensional space to visualize. Since humans can not see in six dimensions(or even imagine anything like it),we are restricted to use low dimension crutches to model what is happening

You can't really answer how in english language. If you search "A Universe From Nothing", Lawrence Krauss has a good lecture on the big bang.

u rock

wow, really helped with my homework. thanks !!!!!!!! really enjoyed watching this
-
so helpful for my physics homework, top job!
-
I was a curious child, and i had a lot of questions. Now I can see that all the answers I got were total bullshit. Big Bang theory is pure nonsense. Stop lying to kids Phil.
-
as a question of science not of christianity even though i am a christian how did this happen if there was no time or space there was no way for this to happen and what if you went outside space where it is still expanding?
-
Hey Phil, I heard from Nassim Haramein that we are spiralling along in a path towards the sun or following the sun through space and time, and that we are not actually returning to the same orbital path like on a record player. Is this true??
-
But if the earth is 6013 (today!) years old, how can this be true? :P

"Big bang" is an absurd creationist myth. We have no evidence that the universe is anything other than infinite in size and ageless. The idea that "space" exploded or is "expanding" is nonsensical. Space is a virtual coordinate system that has no empirical referent. It is utterly imaginary. "Expanding space" explains nothing we see in space. Galaxies in clusters do not support "big bang". There is no evidence supporting "big bang", astronogers believe in it based on faith.

@billythewill67 If a theory is an accurate model that describes something true and universal about how things work, then it won't be disproven. It may be supplanted by one of more detail or descriptive power. We should also keep in mind that a theory is useful only so far as it works. There is no "gravitational force" a la Newton, it's an inherent property of bent space, not a force like magnetism. It's just a useful shorthand for something real.

wow!! those 6th graders asked some really difficult and intelligent questions!
-
Thank you for postinng a video for everyone who wants to learn. I absolutely agree with you about the excitment and beauty of science!

@Ripley747 haha sorry now i get it i just couldnt find the comment i wrote and god could have made the big bang too? yea well what ever i dont care anymore haha
-
@Ripley747 but there is a possiblity of god..or did u say that haha i didnt really get what u said haha sory
-
I think we are acutally wasting time studying how the universe was created, what's the importance of that anyway? I'm talking about NASA and scientists and so on but thx for your video it's very onformative

Space has always been. And space is endless. The universe started with absolutely nothing in it. And when has science ever admitted to be wrong. They would lose their oh so praised monkey man theory. Animals made us this time. And the times before who knows. Other planets have had life but are now dormant. Just like earth will become dormant again. But life will spring forth as always. And someone else will be wrong leading the next life forms to doom.
-
I believe the galaxies and the universe grew slowly. Just like life grows slowly. There had to be a lot of death to get all this dirt in the universe. So alot of things had to die. Therefore a very slow growth.
-
if the galaxies move apart from from time, then thousands of years ago, maybe a galaxy that contained suprior aliens were actually really close b4 but now they r very far away
