I love this guys smile. He’s just always smiling

[ereynolds]

Brian cox is going to be one of those names in the future that scientists and just people in general talk about being inspired by. As a fairly.. uh, not young guy anymore, he still makes me feel child like glee when discussing the stars.

[nickkrepeniotis]

And after a collision like this, "Things can only get better". True story.

[Leehuss]

Love Professor BrianCox, I watch him EVERY time and feel he is OUR teacher. Educating us with his knowledge in space/astrology...

[waynejones]

The moon is very interesting ... with an amazing story to tell.

[Charlielizard]

Brian is such a humble man, yet excellent at communicating his thoughts on physics without doing so in a condescending manner.

[Zapat-rmky]

so good, I like how on top of being a great Astro Physicist Brian Cox is also a great hymn singer Fun fact all these ominous, soothing BG hymns you hear in his shorts are sung by him, 's truly remarkable.

[michaelcurtis]

Really like him given verious possibilities and with ice rocks/meteor/asteriods all makes sense maybe a combination of . Love his theorys!!!

[arivindharanbalakrishnan]

The amazing thing about this is that no one knows if this is true..

And what happened to the hole left in Earth left after the Collision? And what / where is the hole today as we know it?

[BasitKhan-xpoj]

We think it is what we should focus on

[charlieg]

What would be the duration of the collision? How much time would somebody have from the time you see a small dot in the sky to impact?

[Hubris]

I think it's really rare that two planets collide and thus why earth is so unique with its molten core

[the_original_Bilb_Ono]

Can you even imagine what that collision was like? My brain cant even begin to put such an impact into perspective. The earth was most molten at this point correct? I just cant picture what would happen close up, its like trying to imagine the center of a star.

[boomsaucexx]

I like listening to him talk. It’s always truly cool facts and he clearly has a passion for the knowledge.

[lazaruslazuli]

what isn't mentioned is the other planet's core was absorbed by Earth, so that the Moon is mostly crustal material. What core it does have is pulled toward the Earth, making it off-center, because it is tidally locked (the same hemisphere faces the Earth.)

[etan]

Man, could you imagine earth with rings? It would be so cool for us to see a planet in the sky every day

[jonathanjones]

The guy was also a brilliant musician, dare and D'ream.

[iloveplasticbottles]

Imagine how different life would be had that planet not crashed into earth. How different human society would be, with them having possibly seen Theia and made their own legends about it.

[mikey]

I never understood this theory. If this created a ring around Earth that coalesced into a moon then why do other planets still have rings? They also say that this collision is what caused Earth's rotation. If so, then where did all the other planets get their rotation?
