How to Experience Weightlessness (Without Spaceflight)

Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! In this video we explore the different ways we can make microgravity happen here without needing to go to space! A crucial thing for testing all your space tech as well as astronaut training!

The NASA support system started as a simple inclined plane for training during the Apollo program. Where most of the astronauts weight was supported by cables as they figured out how to walk sideways along the plane with only 1/6 "gravity" keeping them in contact with it.

I would be curious how much power (kW) does the 19T magnet consume? Nice video Dr. Maggie, (side note I love the song on the end of your video!) 😺👍👍

amazing explanation! i saw the parabolic flights videos before

[gregorymccoy]

Thanks again for so much interesting knowledge. One of the methods looks like a clock-work tourbillion. Hope that is spelled correctly. If I understand that correctly, it ensures a watch spring is not influenced by gravity in the same plane all the time.

where did you get this "need more space t-shirt"? 🙂

[Andy-dffj]

The drop towers and the parabolic flight are the only methods realistically replicating zero g since they are putting the subject in free fall. Everything else just resists gravity with another force.

I experienced a “vomit comet” parabolic flight a few years ago. It was a great experience. Felt like the drop from a tall roller coaster without the terror. We got about ten or fifteen parabolas in during our flight. It requires very skilled pilots to hit free fall without negative g forces. They give everyone an antinausea shot before the flight to keep the plane clean these days 😉

I am new to your channel and I love your videos ❤

Thanks so much for creating and sharing this informative video. Great job. Keep it up. 😻

5:12 - Lab rats watching this: "We count as live organisms, right?"

[johnlewis]

Brilliant! I quite like the idea of parabolic flight but I don’t think I’ll be able to afford it

Can Dr Lieu's facility duplicate the double headed c elegans results? Probably good for a paper. How about testing pharmaceutical production? Costs are crashing with SpaceX though scheduling is still difficult. Maybe run a proof of concept in Dr Lieu's lab before scheduling, waiting for, a full run on ISS or its successors. Developing the techniques for production in Dr Lieu's lab would be good for some papers too.🙂

excellent video, very well presnted 💯

[KaiseruSoze]

jumping on a trampoline, sky diving, clif diving are good simple and cheap ways of finding out what 0G is like. You can also get a short time in 0G in a private plane. Take a look at the zero g dog.

Dr Becky's got nothing on you my dear
I wish you a million subscribers 🥀

Hello, I am new in your channel, it seems very interesting to me, gravity is a misterious force but antigravity is more misterious, I did an experiment and could create a gravity wave but it lates only microseconds, I want to create a device to cancentrate and amplify this wave, may be I achieve it some day. you are great and wonderfull lady go ahead!!!

[themog]

Hello Space Mog
Pleased to meet you :)

[Allan_aka_RocKITEman]

FWIW: Never heard of a "Clinostat" before.

[humanrightsadvocate]

what are those things on your eyes?
What is that?
Are those brushes?

[gyrateful]

As I get older, my perception of time speeds up, so should that not reduce my mass? Or, my perception of gravity?
