UFO's and why they blink out.

I repeat: it has nothing to do with modes of thrust. It is simple fact of the compression of the air, caused by the movement of an object - any object - through faster than a sound wave can carry away the compression. Even a shell or a bullet makes a sonic boom of sorts, if it is moving supersonically. Read the article. That makes it perfectly clear. It even gives the example of the crack of a bullwhip.

exchemist I realise that . old news quite frankly, very old.

So we can see why they can seem to " blink out " . Because within one second these craft will have gone at least a half a mile.
Plus I think this refutes this " another dimension theory " as to why they just blink out or just disappear.
The most puzzling thing about all this ; is that ; nobody has bothered to do these simple calculations before.
These simple calculations changes one's perspective .

That prompts a question: why has no one reported the SR-71 "blinking out"? Or missiles?
Or even - at 5-10 times the "speed of UFOs" - the Space Shuttle?

I am not claiming anything is new.

Merely that a supersonic UFO would not "just blink out", it would make a hell of a bang as it passed. As a meteorite does.

fair enough

since no sonic bang or boom is ever heard ; one must think ; differently

I did some very basic calculations on the speeds of UFO'S ;

For instance ; at

2000mph = divided by 60 mins = 33.33 miles / min.
by 60 secs = 0.56 miles/sec.

5000mph = divided by 60 mins. = 83.33 miles/min.
by 60 secs. = 1.39 miles/sec

10,000mph = divided by 60 mins. =166 miles/min.
by 60 secs. = 2.7 miles/sec.

50,000mph = divided by 60 mins. = 833.33 miles/min.
by 60 secs. = 69.45 miles/sec.

So we can see why they can seem to " blink out " . Because within one second these craft will have gone at least a half a mile.

This seems to assume the following:
1. that the UFO is visible (i.e. travelling slow enough to be observed) and then instantly travels at a speed so fast that it appears to "blink out".
2. that the UFO does not actually travel through air - as if it did and travelled above c. 340m/s then it would generate an audible "sonic boom" due to breaking the sound barrier.
3. that there isn't some far more reasonable explanation for the UFO that does not in fact entail "blinking out".

The math you post does not itself address why things blink out, it is the assumptions that you seem to be making that would do that.
Plus I think this refutes this " another dimension theory " as to why they just blink out or just disappear.

Not at all, as "another dimension" would possibly explain why they can safely accelerate from low speed to such high speeds.
It could also explain why there is no sonic boom accompanying the travelling at such high-speed, although other "theories" might also do that (e.g. warp travel as in Star Trek).

I'm sure they have, but as said the maths itself is no explanation for anything, is not a theory in and of itself - it is, if anything, merely part of a theory.

Not really: the more likely explanation is that there are no UFOs of alien origin, that the "blinking out" is merely an interpretation of a rather more mundane cause.

I see; so have you researched the UFO phenomenon ?
 
I was hoping you might get an education. It seems we are both doomed to be disappointed.

Here's what pisses me off about fools such as yourself. I think there is a very small, but still finite chance that a very small percentage of UFOs may actually be alien spacecraft. I think there is a marginally larger, but still pretty damn minuscule chance that a very small percentage are some heretofore unrecognised phenomenon. However, giving any attention to these possibilities invites ridicule and is effectively discourage because deluded cretins, such as yourself, have so muddied the water.

If you seriously wish UFOs to be taken seriously then shut the **** up for half a century and let the mud settle. Then we might just see something.

Who are you referring to ?

If its me river ; then say so ...I'm not going to bash you .

This simply provides further evidence for the hypothesis about you which I formed in August 2013, when I attempted to have a discussion with you about water.

For the third time, the creation of a sonic boom has got fuck-all to do with the method of propulsion. Any object travelling through the air supersonically will create a sonic boom. It does not matter how it is propelled. It does not have to be propelled at all.

And there lies your ignorance of the forms of advanced propulsion.

Now there's an example of hypocrisy, given that your knowledge of "advanced propulsion" is practically non-existent. (Because ignorant fantasies don't count as knowledge).

This is the main point of refuting your OP.

- The calculations in your OP imply a solution to blinking out as a result of very high speed.
- But very high speed results in sonic booms.
- Therefore it does not resolve the issue.

As you say, one must look to other explanations. Which is why hypotheses such as extra dimensions are posited.

This is the reason why, as you say,
"nobody has bothered to do these simple calculations before."
and
"this is old news"
Because it was quickly realized that it doesn't resolve anything.

This thread is not about what I know or don't know. About advanced propulsion

No it isn't. It's about explaining "winking out" with high speed. That was established in the OP. And that's all that was established in the OP.

And it has been refuted.

If you wish to change the topic of the thread (or start a new thread) to be about advanced propulsion, that would be appropriate.

But now you're right back where you started. Resorting to exotic methods of "winking out". Do you have any suggestions less exotic than dimensonal travel?
