$150 space flight

[OldSchoolWWEguru]

@gruntguy I just wonder how these scientist for one, think they know the true size of the universe and with the results from WMAP with the result of Omega, where is there data comming from. Omega=1 meaning no curvature to the universe, it is flat. And how have they come up with the rate of expansion during inflation?

[OldSchoolWWEguru]

@gruntguy ok well thanks for the wiki page, I am going to have to check it out, cause I am still alittle confused on how an equation for gravitation lets you figure out the mass of an object, so hopefully that wiki will explain, perhaps you have an idea for a question I have been having, nobody knows the true size of the universe, but there has been speculation about it with some scientist saying they believe that the universe is 20-40 billion light years radius, with a slight curvature. (m)

[OldSchoolWWEguru]

@gruntguy wmaps calculation for omega is 1, if omega did not equal 1 the universe would have curvature in either a positive or negative fashion. and allowing for a big crunch as the fate of the universe. Yet, how have these scientist come to this conclusion, considering we do not know how far or the rate of expansion in the inflationary period of the universe. The rate of expansion can be calculated now, and more likely than not, with omega being 1 we are headed torwards a big freeze. (m)

@gruntguy i did not think it was space i was seriously interested in the answers of my questions cause i did not know, and was pointing out the irony that you have to be in a suit at that altitude but its not space. thats what i hate about posting it takes out the other forms of communication body language, tone of voice...hey how would you calculate earths mass

[GruntGuy]

@OldSchoolWWEguru Oh okay, sorry if I came across a bit snappy lol.

To determine the mass of the earth, you would use the Newton's law of gravitation again, F = GmM/r2

F is the gravitational force at distance r, G is the gravitational constant, M is the mass of the earth (unknown) and m is the mass of another body at distance r from the earth. Since M is the only unknown, you can use the equation to work it out if you know the other terms in the equation.

[OldSchoolWWEguru]

@GruntGuy I guess its still a little to advanced for me yet, I am just starting my physics major, are the values for all the variables except earths mass fixed? I am guessing I dont understand how you come up with the mass of an object by a law of gravitation. Can you explain?

[GruntGuy]

@OldSchoolWWEguru It's been a little while since I did this stuff (2 years ago). I'm majoring in Chemistry and I took Physics and Astronomy courses in my first year. Yes, all other variables will be fixed/constant. I could try and explain it in my own words, but for simplicity's sake the wikipedia page explains it perfectly: en.wikipedia[dot]org/wiki/Newt­on%27s_law_of_universal_gravit­ation

The first diagram of the bodies m1 and m2 and associated equation is pretty much the key here.

[danschaoticmind]

Personally? I'd like a more detailed study of the mesosphere especially elves and sprites. But most importantly a fully detailed study of the Ionosphere. The only problem is the best you could do for that would be sounding rockets due to the density of the atmosphere (Almost a vacuum but not quite). 

[NEEDCARS]

A ant or something for science :)

[AzziTube]

I would send my neighbours' dog into space for $500

awesome logo BTW

[Adamsrandomjunk]

thats cool

[11chickenlord11]

I tried this and i used a 1200g balloon with 2 cheap 20$ rockets attached tro it, inside i put my dead hampster. when he came back he wasnt a hampster,lol

[SupaChard89]

Birthday post

[mikaila31]

As everyone else is saying. It was the stratosphere, not space. If it actually went into space it wouldn't of come back. LOL!

[jake5680]

Ummm.... NO.

At 250 miles gravity is only about 10% weaker than it is on the surface of the planet. All the things you see about "weightlessness" are actually do to the state of free fall taken around the planet.

PERHAPS you should do a Tiny bit of research before making such a bold comment.

[OldSchoolWWEguru]

hey since you know gravity is 10% weaker at 250, can you show me the formula you used to come up with that? which law of physics governs it? can you live unsupported at 73000 ft? nope you have to be in what? a space suit lol

[GruntGuy]

@OldSchoolWWEguru Newton's law of Gravitation.

Gravitational force = m*g (at radius, r)

Where m is the mass of the earth, and g is the gravitational field.

Gravitational field is defined as g = -G(m1/|r|^2)*r-hat

Yeah, you can't live unsupported underwater either but you wouldn't call that space. The generally accepted altitude at which space begins is 62 miles, or 327 thousand feet. Try getting a balloon up there.

[danschaoticmind]

@GruntGuy Just a note, your measurement of the beginning of space is measured using the Karman line which does indeed define space at 100Kilometers, the University of Calgary reported detailed measurements with an instrument called the Supra-Thermal Ion Imager (an instrument that measures the direction and speed of ions), which allowed them to determine that space begins 118 kilometres (73 mi) above Earth. An interesting study to say the least!

[GruntGuy]

@danschaoticmind Yup, I was stating the Karman line since that's the most commonly used 'boundary'.

Still though, doesn't really matter which one you use here, as I was just trying to prove to "OldSchoolWWEguru" that 73000ft is NOT space. Thanks for the extra info though, very interesting.

[danschaoticmind]

@GruntGuy Ha ha! Anytime man! 73000 feet is still in the mid stratosphere which means that the relative density of the atmosphere is such that sustained propulsion would be needed. I just like sharing new information and ideas when I hear and study them. I'm gonna be taking some leave myself here in the next few days and using what I know and have available, I intend to give this one a try myself. I'd like to have at least a device to study the local magnetic fields along with a camera.

[LKott]

This guy is a complete dumbass.

1) It did not go into actual 'space'. It went into the upper part of the stratosphere

2) Why would you put in anything other than a camera? It's just coming back down anyway.

I'm doing this in a couple weeks. But instead of using a 350g balloon. I'm using a 1200g balloon. Goal height is 117,000 feet.

[slipkitten]

Thank you for the comment, I hope your balloon does well.

[TheShadylibrarians]

I don't thing I'll send anything I'll keep my $150 lol

[slipkitten]

nice

[katieoler]

Cool video but considering the object is just going to fall back down to earth, what would be the point of sending something other than a camera up?

[DawnWeatherby]

I think that this story is really cool also. I am sorry to pop your bubble (Pun intended) but technically they didnt reach space. It was near space. It still is a cool story and they are planning to post a video on youtube using all of the photos taken by the camera.

[tattoozombiegirl]

Cool!!!!! i would send....hmmmm maybe today's paper!!!! Wonder if it would stay up there longer!!! link did not work!!!

[slipkitten]

Posted new link. thanks

[tattoozombiegirl]

Thanks Hun, the pictures were incredible!!! so awesome!!!

[Kizzyme]

wow that's kinda cool. I don't think i would've liked to send something up there though xD

[slipkitten]

just saw your first vid....Nice

[Kizzyme]

hahaha xD thank u , i think it was REALLY funny:P darn xD

[stevensj13]

How would i do this? Any links to a site for more information? That is very interesting right there

[slipkitten]

just put up a new link but they are going to make the plans available, however this could be very dangerous so I would not recommend it at home lol

[xxmistakensin]

Is that for real? seems almost impossible. Link didn't work for me.

I would try to send something with my name and a return address and hope I get some nifty space gifts.

[slipkitten]

Yea its real , and its real cool. posted new link btw

[stevensj13]

I would send up a Computer with infinite battery life and videos of the worlds technology today, that way in several hundred yeah the future people will see how life was for us

[slipkitten]

Nice , I like that idea..and just think technology for ten years ago seems archaic .

[sublimegirl95]

Omg thats so cool =)

[slipkitten]

that's what I thought also.
