I'm curious: why wasn't the Hubble Sphere called the Hubble Bubble? How much toil and trouble would it be to change the name?
-
I wanted to call this series "In here 🧠 Out there 🌿"
-
I hope you see this, get well soon we miss you!!!!!
-
I love everything space related and the way you put it for us not so smart folks is just great! Keep doing what you’re doing. Ps. How can I steal your editors job?! I would LOVE to learn on the job lol

6:05 "The space between two objects can expand such that it moves those objects apart faster than the speed of light." This is perfectly worded. It acknowledges that it is a speed (distance over time) while still highlighting the difference from what we would normally consider a speed.
-
The concept of light traveling towards us while also moving away from us as space expands reminds me of trying to walk the opposite way on an escalator...although I'm sure it's quite a bit more complicated than that analogy, if I understood anything from this video
-
Hope everything is getting better!!!!

Thanks for the great explanation! Something which always bended my mind. I would love a follow-up, where you explain how during a Big Rip, one of the horizons gets closer until light from even say Andromeda wouldn't reach us anymore, while the observable universe still gets larger as time since the Big Bang increases. I'm still a bit confused about that, how that works.

Your editor sounds really smart
-
During the ad, she says that I probably have a 3M product in arms reach. Since I'm physically at 3M Center (I work here) this is absolutely true.
-
Listening to you and watching your videos are just so captivating
-
I'm just going to watch your videos again. I've always enjoyed learning from you. Rest as much as you need but please don't quit. I'm sending good vibes your way. ♥

Just imagine the wonders and poetry of deep space . No limitations. As Stephen hawking once said " There should be no boundaries to human endeavor. We are all different. However bad life may seem, there is always something you can do, and succeed at. While there's life, there is hope."
-
Just when you think you're beginning to understand the universe it humbles you and you've got to rethink everything. Love your videos. Thanks for sharing this knowledge.

I’m a huge fan of all things science and Physics Girl. She’s a great science communicator and I look forward to watching her career unfold over the coming years. Live long and prosper.

Damn I think I actually understood that. It's a bit like a car moving north at 60mph and you jump off south. Even though you jump south, you're still going north. Same thing with the light. It leaves the distant object still moving away from us, but eventually it works it's way to moving toward us at the speed of light
-
Mr. Editor: you didn’t give her the slide transition! Awwwww.

I am currently attending school at south Albany highschool in Oregon, I was told by my physics 2 teacher mrs.Jones that this girl went to the same highschool and was taught by the same instructor. It’s great to know I have such an amazing physics teacher who can mold minds as great as the one we see in this video!
-
I miss her regular videos. Get well soon physics girl! The world is praying for you
-
I love the stuff you talk about u would be fun to figure out things you really get heavy.i have not met to many people who be heavy about a subject keep up the good work 👍❤❤
