Neil deGrasse Tyson Explores The Vacuum of Space

I don't understand. I can create a vacuum that can over come gravity on earth, but space which is a stronger vacuum then I can create can't suck all the air out into space?

New Video: Watch Neil deGrasse Tyson explore “The Vacuum of Space” with Eugene Mirman in this Cosmic Query: Neil deGrasse Tyson Explores The Vacuum of Space

[iwannaseenow]

I had a gf who could create the most perfect vacuum on earth.

[Mhats]

it would be like putting a straw in a pool of water (atmosphere) and the other end in air (vacuum), the water doesn't rush our because of the gravity

[bronneberg]

Even with a gradual decrease in pressure as you go higher, there is still a differential that 2nd law of thermo dynamics will want to equalize. Even if space doesn't effect air on surface of the earth it will still effect the atmosphere closest to it and suck that part out, and then move a little closer and closer till there's nothing left.

[glenphillips]

How would you prepare, manufacture & test seals for space on the iss if you cannot replicate the strength of vacuum here on earth ?

[gulis]

definitely not a bubble. the steam like depend on the characteristic of the gas inside, and the ligth you use to look.

[michaelWakka]

1. It's spelled abhor. 2. Dark energy is energy, not a particle. 3. Dark matter has not been proven to be matter, it's just an unknown source of gravity.

[WhoElseButZane]

What would the air coming out of the jar look like? A bubble? Or steam looking?

[Linkwii]

He been to places where other scientist do experience and he have access to more info than any of us who click on videos.

[djdedan]

would the container get crushed if it was brought back or no?

[phreshkru]

How do thrusters and fire work in space? Do they test the space suits in a vacuum?

I try to combine the cosmological constant and the schrodinger solution on the planck scale.

I used planck units.

At the end I went back to SI units to compare with the measured vacuum energy density (0.63 10^-9 J/m^3.)

Combine:
1)     Einstein, cosmological constant
2)     Schrödinger solution
3)     Planck units

Result:
-        vacuum catastrophe solved?

1)Einstein, cosmological constant

Λ = (8π 𝐺 ƐΛ)/(𝑐^4)

Planck units:
G=1
c=1
Λ (6.1871424 10^34)^-2 = (8π ƐΛ [planckEnergy/planckVolume^3]

1.1056 10^-52 (6.1871424 10^34)^-2 = 8π ƐΛ

0.001149 10^-120 = ƐΛ

0.1149 10^-122/ ƐΛ = 1


2)Schrödinger solution, n=1

(ℎbar^2 𝑛^2 𝜋^2) / (2𝑚𝐿^2) = E

Planck units
hbar=1
n=1
m= mplanck =1
L= Lplanck=1
0.5 𝜋^2= E

1= E/0.5 𝜋^2

 
3)Einstein, Cosmological Constant = Schrödinger solution

0.1149 10^-122/ ƐΛ = 1 = E/0.5 𝜋^2

0.1149 10^-122 0.5 𝜋^2= ƐΛ Eplanck

Eplanck =1

0.1149 10^-122 0.5 𝜋^2= ƐΛ

0.567 10^-122 = ƐΛ [planckEnergy/planckVolume^3]

0.567 10^-122 1.9561 10^9 /(1.61625502 10^-35)^3= ƐΛ [J/m^3]

ƐΛ = 2.627 10^-9 J/m^3.

Measured: 0.63 10^-9 J/m^3.

I am looking forward to your response.

Neil deGrasse television star? Scientist? Theorist? Has he discovered anything himself or just piggy backing off others “theories” or worst others hypothesis?
He founded the department of astrophysics in 1997 and has been a research associate in the department since 2003.
He served on a 2001 government commission on the future of the US Aerospace industry, and on the 2004 Moon, Mars and beyond commission. He was awarded the NASA distinguished public service medal in 2004.
He hosted the television show nova science now. He also hosted the television series cosmos: A space time odyssey. The US national Academy of sciences awarded Tyson a public welfare medal in 2015 for his extraordinary role in exciting the public about the wonders of science.
Neil DeGrasse is a NASA public relations mouthpiece, with no true discoveries of his own. When you listen to him talk it appears as if though he is making it up as he goes.
From what I gather Neil deGrasse is a well educated NASA and Science PR expert and television star.Who talks about the discoveries of real scientists. He is no different then bill Nye the science guy, a mechanical engineer and television star.
Neither of these men have made any significant contributions to science.

[Hdhillon]

its basic principles of physics actually. Once you have a solid understanding of a certain phenomena, you have a thorough understanding of the universe. But there are very few people one this planet that have reached to his level.

[dont.trust.anything]

How do we know there is any vaccum at all up there?

[thejokester]

The vacuum of space properties should be studied we could probably find a way to travel faster than the speed of light if we know the properties and everything about it

[Phi]

Apart from the quantum oddities, like virtual particles coming into and out of existence, a total vacuum in a jar is as close to nothingness we can comprehend intuitively, let alone be useful in any way.

[natecal]

What if we were to put one end of a straw of some kind in the vacuum of space and the other end in our atmosphere? Would the air rush out into space?

[Grilinctus]

The first time I tried watched this it was three and a half minutes of black video and no audio and all I could think was, ‘well played’.
