We can see things moving faster than light

How is it possible for galaxies and objects in space to move away from us faster than the speed of light? Will we ever see those objects?

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 🌿"

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.

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

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

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 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

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."

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.

[neurotransmissions]

Wait, so does that mean that, even if it were possible, we would never be able to see the “edge” of the universe because it’s moving away faster than the speed of light? Or am I misunderstanding?

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.

I live in Argentina. My 10 year old daughter loved your video but she relied on my translation to understand it. You should make a channel with a Spanish translator in the audio. You would capture many children and adolescents in these latitudes. You have a great way to spread science. Keep it up.

[johnchessant]

Fun fact: If the universe was expanding at a constant rate instead of an accelerating rate, then there would be no event horizon; light from every object would eventually reach us. This is called the "ant on the rubber rope" puzzle

I hope you see this, get well soon we miss

Mr. Editor: you didn’t give her the slide transition!

I love how passionate and excited you are about all of this stuff, it is absolutely infectious and your videos are always a joy to watch.

It's great to see your excitement when talking about cosmology, I see it in you and I know how you feel, I am 57 years old and have been into Science, cosmology and space since I was very young after seeing the Moon landings that was the spark for me. It is a lonely subject to be into because in all my years I have had very few deep conversations about cosmology and when you meet someone who wants to listen I just feel like I can't get it all out with the excitement. I still think and watch about cosmology, Science and space every day and am still as excited like you about it all.

[danielsiebert]

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.

4:38 The Scotchlite is vastly used in motion capture because MotionCap camera takes profit of this specific property to reflect the light in the opposite direction. that's why they have multiple infrared LED around the camera.

This has just become my "go-to" method for persuading people that I'm smart.
Great video; clearly explained; with good use of props and diagrams to illustrate potentially confusing concepts.
5 STARS!
Sorry, I couldn't help myself. Granting stars on an astrophysics or cosmology video is empowering.
