UFO / UAP

[Koolpc]

Ok guys, enough is enough, who is joining me and putting Jimmy noseitall on ignore?

I have just done that! Yay!!

No more Jimmy!!!!!!!!

The bloke is just trolling and posting up theoretic nonsense to excite the trolls.

The UFO trolls on DIYnot having a rational thought, seems to be impossible.

On both counts a reminder that we are talking about UFOs so given that then everything must be considered for discussion

 

[Iwilldoit]

No. Many sighting from going back hundreds of years....

So What Were UFO Sightings like in the Really Old Days?

J.J. Grandville , 'A Comet's Journey' , Illustration from 'Un Autre Monde', 1844. Who made the little green spacemen, well, green? Long before the midcentury Space Race set the standard for collective extraterrestrial clichés, people were having out-of-this-world experiences that chilled them dow

Why have you started calling noseall Jimmy? It seems a bit random!

Thats his name...

Well if he is using "boyo" which actually comes across as passive aggressive then from now in its going to be Jimmy for him.

You're applying today's tech to the problem. Nobody serious is suggesting, we can do any of this today, with the right funding. You're also assuming the vessel will start and end as one.

Today's technology, partially. The raptor example is a good demonstration of why chemical propulsion is a dead end. But when you talk about Pulsed fusion drives, which have a similar or worse Thrust per Ton to Hall Effect thrusters, then that's not todays technology, that's a century or more out.

And some of this isn't about technology, it's about fundamental (and fairly simple) physics. The physics behind reaction drives are more or less Newtonian, it's all about the speed and mass of the thing you're throwing out the back.

With a reaction drive you can get the ISP (the efficiency) from 400-500 which is the theoretical limit for chemical reactions, to 10,000 for fusion pulse drives, but even then the masses involved are stupendous.

And my numbers didn't include any of the body of the theoretical spaceship or consider staging. That was a 'pure' calculation based on a 400 ton dry mass and ignoring the rest of the rocket. Which is ridiculous as each Raptor Engine weighs in at 1.5 Tons alone. 400 tons is the weight of the ISS or two SuperHeavy stages.

So refreshing not seeing that idiots posts that are just so abusive towards certain members on here....just no need for it.

 

[noseall]

So you know for a fact that life does not exist on the sun at the moment?

Yes.

 

[noseall]

make your mind up.

Sending a piece of equipment and sending human beings are obviously two very different propositions. A high risk, three year trip is not very appealing. Plus we'd have to somehow feed and water them. And the costs involved will be astronomical.

I have made my mind up - and yes it's a pipe dream drummed by Musk, perpetuated and repeated by Trump and swallowed hook line and sinker by the gullible horn-smokers. If there is still an appetite for space exploration in four years time and a few trillion dollars to waste, maybe humans can find the will to put a flag on Mars. I have my doubts.

Travelling beyond that - not in your wildest dreams.

 

[Highway Man]

Yes.

So how did you come to this conclusion?

 

[pete01]

for space exploration in FORTY ISH years time and a few trillion dollars to waste, maybe humans can find the will to put a flag on the MOON. I have my doubts.

Beyond that - not in your wildest dreams.

You would have said that ^^^ in 1925?

So when the flag is on Mars, what next?

Sorry for altering a quote.

So you say a man can put up a flag on Mars then in the same breath you say not in your wildest dreams. I would saty this is the ramblings of a fool.

OMG can you imagine how the world would be if we relied upon noseall. ~We would all still be living in caves and the wheel would still be in the making.

The wheel?? It will never catch on

can't be done. impossible
