Is this guy for real?

Chekhov really partied a little too hard.

This seems to be a popular view among the extreme end of hoax advocates.   Heiwa,  a HB who among other things believes that all manned space flight and all nuclear weapons are fake, got kicked off of the clues forum for saying that unmanned satellites are real.  Everyone else on that forum believed they were fake because rockets wouldn't work without anything to push against.

Now there is some serious irony.

He has some other gems like Noshot and one concerning fluoridation. I didn't view either but left some pertinent comments on this video in YouTube.

What to push against? Air? But air density is neglible and its only a problem when flying up due to aerodynamic forces. Also the pressure of the propellants are higher than the air on the chamber, the third newton law is totally independent from what "to push against" if im not mistaken.

That individual has a lot of issues  concerning physics for sure.

You're not mistaken but HBs aren't interested in the lies of mainstream physics.  Physics made up to fit the pet hoax idea is much more interesting.

Yes, but they are not true if they contradict supported models. It makes me sad that people who doesnt knows about physics are falling for this.

I meant to use the term "lies," sarcastically.

I think it's a case where people without much background in physics try to use intuitive, "common sense" thinking. In our grounded world, we step or move by "pushing against" things. If a giant hand picked up a car, its wheels would cycle uselessly with nothing to "push against".  The fact that the gas in the rocket "pushes against," not the atmosphere but the rocket itself, isn't as obvious.

Then there's the misconception that a craft in space would have to endlessly burn fuel for propulsion, rather than coasting with no friction. A mind expecting Earth conditions will expect the craft to come to a halt with no further propulsion, and it's hard to rewire one's thinking to accept this.

Yes, I know. The problem is that a lot of people dont have the skills to detect those "lies" and thus they fall for them.

I wonder if the individuals who spout such nonsense are only trying to get reactions, sto(r)king their ego.  I've noticed that Jockndoris comments on how many views/comments his post illicit.  In addition they try to show to the novice observer, that they "know" something that nobody else knows.  Again this boosts the ego that is involved.

The idea isn't new at least. The New York times published an editorial in 1920 (https://en.wikisource.org/wiki/The_New_York_Times/Robert_Goddard) making the same claim. However, now that we have satellites in orbit anyone could observe, the idea is slightly less credible than it might have been then.

...this boosts the ego that is involved.

That happens to people who suffer from the terrible affliction of more ego than brains.

Yes, but it could be argued that they may have a deficit of ego, that needs to be boosted.  Either way they aren't using brain functions in analyzing what they are proposing.

Things like the vid in the initial post make me almost suspect that there is, in fact, a conspiracy afoot - one whose aim is to discourage people from pursuing STEM careers. Ever notice that a great many of these horrid, horrid videos take great pains to portray intelligent people as nerds? There's just a really creepy anti-intellectual vibe to so many of them.

I've had the pleasure of getting to judge some local TARC qualification flights, and it does encourage me. While the internet is obviously chock full of wackos, it's always refreshing to see those team members at work. They're part of our space future. (one of our junior rocket club members from way back went on to become Rutan's chief aerodynamicist on SS1...). STEM is good.
There's hope.

What was the ~ maximum altitude any reached?  Any liquid propelled vehicles or just solid?
That must have been fun indeed.

The challenge in TARC is to lift a given payload, with a given motor, to a predetermined altitude, and land within a predetermined flight duration. The variables are overcome using the rocket design (weight, drag), winds, air density, recovery system (parachute size), coast delay duration etc.

Our kids are practicing here at around 6000' msl, and the competitions are held near sea level in Washington DC...still another challenge. It's really satisfying to see them at work...

I'd never been to one, just read about there being competitions.  Good fun and education.
