$150 space flight

2 MIT students launch balloon into space for $150.00 . If you could send something into space what would it be and what would it do . Leave text or video response.

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.

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

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

[slipkitten]

nice

[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 .

@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 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 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.

@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.

[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 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.

@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

[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.

[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.
