the comet should be named the billings 51
hiiii from Michigan !!!! I think science live videos are cool.
we will never be on the lookout for a comet!!! anyways I love acellus so much even when I don’t have the energy to do my school work I know that i’ll always be on the same thing then I was on when I was doing my school work.. thank you so much for this awesome program and school
I can’t wait to see the comet.
I had no idea that a comet had a nucleus, and the fact that there’s a national inventors day.
* I really the part where Dr. John talked about the cool comets. I also really like the part where Dr. Tobias talk about the bullet train.
I really would like to ride the Bullet Train one day!
I hope everyone has a lovely Valentine’s Day.
This concept is amazing. Thank you so much!!!
I’ve never seen a comet before that would be amazing! I love watching Science Live
this episode was absolutely great
What an amazing Science Live! Happy national inventor’s day!
I enjoyed hearing about the comet!
Such a great thing to learn about I really hope we get to learn about this again soon
At what point does a bullet train become more efficient than flying?
Comets are so cool!
I love looking at different pictures of comets.
Comets are really cool and so beautiful!
omggg i hope i can see the comet!!
I’m excited for the comet!
I wonder if there will be another Thomas Edison in our generation
What is the fastest train in the world?
I love comets and astrology too I hope to see more
I was really rooting for Alvin in the you build we judged but I guess I was wrong
I loved it and happy Valentine’s day.
Very interesting evolution in technology.
How can we utilize the integrated circuit effectively? And how can we follow?
Science Live is so cool, it’s awesome!
The comet should be named the Pajet comet.
the comet should be named greatness.
Love learning about space!!! Yayay cant wait to watch the next one!!
r51 is can never be a waste of time.
I love watching Protégés.
tuned in from north carolina! always love these discussions.
This school is very helpful and I enjoy doing it.
Would be so cool to one day ride the bullet train
It’s crazy how the bullet train, one of the fastest modes of transportation, was made in the 1950s. Technology is advancing too fast
This weeks science live was really good, always love the science news?
The comet is going to be CRAZY! I can’t wait.
I wonder if we can use the moon to put solar panels for energy. Awesome video!
We laughed so hard watching and learning from the proteges. Thank you.
I learned that the vacuum tubes go on and off. It’s so much fun to learn about the circuits from the protégés.
This was an amazing Science Live. I had so much fun! Looking forward to seeing the next one, as always! 😍
The comet is so neat! And the story about the trains, I absolutely loved it!
Wow!!! This was sooo cool and fun! I had so much to see I don’t even know what to say! 😆
I wanted to make a second comment, thank you very much, Dr. Billings!
I love science live.
Why do they name comets and asteroids with letters and numbers?
I love Acellus learning it helps me so much. Happy Valentines. Hope you’re having a great day. I am.
I’m not excited to watch for the comet.
Perfect video, would love to see more on circuits.
I think the comet should be named Comet X
Can’t wait for science live each week!
It’s crazy how far computers have come
I find comets so interesting!
Great science live, also happy valentine’s day!
I love Science Live, I never knew there was a national inventor’s day. Wow!

The comet is very interesting.
The video is about comets and bullet trains.
This live is the best live I ever seen! I love learning!
I think we should name the comet the Acellus of space.
This past summer I saw what I think was a comet zoom right across the night sky over northern Vermont. It moved so fast but was so bright. I had just happened to be looking up when it flew across. I look forward to seeing this comet in April. The protégés are serious and professional but also funny and great editors with good taste in music.
I think comets are so cool! Will be on the lookout
I’m so excited for the comet! Sounds sick! Me and my family will be on the lookout for it!

How many comets came from that group?
I would be too scared to ride the bullet train despite its safety record, but I did like learning about its development. The comet should be named Maverick.
I love the humor in these videos!!
so cool! With Science Live i always learn somthing new!
How big is this comet.
I think the comet should be named “The great comet of 2026.”
I think the comment should be named Jeff.
I liked the comet talk. The bullet train is cool too. The guy signing made me laugh.

how much electricity did they need?
Like the protojeys many of the smartest and most brilliant people such as Leonardo DaVinci with Andrea del verrochio at one point, they learn and they come up with their own ideas togather and become inventioners.
Bullet trains are my favorite trains.
Do comets hit the sun?
Thanks Dr.B

Clara Lux sounds like a good name for a comet to me. It means bright light in Latin.
Thank you for this week’s video. Looking forward to next week.
I think it’s really interesting how computers used to be the size of a room, and now they can just fit in our pockets.
Are Integrated Circuits cheap?
I enjoy the story about the development of the bullet train in Japan, highlighting the challenges and successes of the project.
