Do UFO's break the sound barrier?

Brilliant question...and you've all supplied interesting, but practical answers...well some of you anyway. Not calling names. LOL

No matter the answer...it is beyond human science. It is not beyond human understanding however.

I've never heard anyone mention a UFO sighting & have stated that they actually heard anything from the craf. No sound at all. The UFO I think I saw...the same applies to it. I didn't hear one thing.

Maybe the technology they use does emit a sound...but maybe higher or lower than what a human can hear. Infrasound or ultra sound?

Also, I'm sure we haven't been visited by only one race of aliens, with many different ships. Maybe the technology one race uses isn't used by all. Some may make use of this "bubble", while others simply eliminate air entirely...while others produce infra or ultra sound. Again...brilliant question.

That is a good idea. It is my understanding that the human ear only can decipher any percentage of all "sound". I still think that regardless of the sound the supposed craft eminates, the "boom" would be there nonetheless. I think that the "boom" happens from the reaction with the atmosphere but not necessarily from the craft itself (I could be way off on those 2 sent.). I also have read that breaking the sound barrier is not a clear cut issue. Different atmospheric conditions have an effect on your ability to break the sound barrier. See below from aerospaceweb.org:

Background information can be found in two additional questions we've already adressed covering the speed of sound and how fast is Mach 1. But since we get various versions of this question over and over again, we thought it would be easiest to provide a comprehensive table of values for the speed of sound throughout the atmosphere in common units of both the English and Metric Systems.

The second table is in the Metric System and indicates the speed of sound in kilometers per hour (km/h), meters per second (m/s), and knots (kts) for altitudes from -4,000 m to 122,000 m in 2,000 m increments.

The tables are also color-coded to correspond to different regions of the atmosphere. These regions are defined by the behavior of the atmospheric temperature and (by extension) the speed of sound as altitude increases. These regions include:

The atmosphere is broken down into regions of decreasing temperature (blue), constant temperature (green), and increasing temperature (red). This behavior is further illustrated below for the Troposphere, Tropopause, Stratosphere, Stratopause, Mesosphere, Mesopause, and lower Thermosphere. Above the Thermosphere is the Exosphere, which is well into what is considered to be space.

The Mach 1 tables are .gif image files that you can download or print for future reference. Furthermore, the tables can be used to determine the speeds associated with multiples of Mach 1. Mach number (M) is a ratio comparing the velocity of a vehicle (V) against the speed of sound (a): If you want to know a multiple of the speed of sound at any particular altitude, simply multiply the value of Mach 1 at the altitude of choice by the desired Mach number. For example, Mach 5 at sea level is 5 times the value of Mach 1 at an altitude of 0 ft (0 m):
Mach 5(SL) = 5 * (761.2 mph) = 3806 mph
Mach 5(SL) = 5 * (1116.4 ft/s) = 5582 ft/s
Mach 5(SL) = 5 * (340.3 m/s) = 1701.5 m/s
Mach 5(SL) = 5 * (1225 km/h) = 6,125 km/h
Mach 5(SL) = 5 * (661 kts) = 3305 kts
These tables were created using the 1976 US Standard Atmosphere. Unfortunately, most textbooks and computer programs that provide Standard Atmosphere tables only go up to a height between 200,000 and 295,000 ft (61 to 90 km). Sources that do provide speed of sound values beyond these altitudes are rather contradictory. To extend our tables up to 400,000 ft (122 km), a few known data points were used to linearly interpolate the remaining values. While the Mach 1 values provided for the Thermosphere may not be precise, they should be reasonable approximations. Beyond 400,000 ft (122 km), the air density is so low that the atmosphere essentially ceases to exist and the speed of sound becomes undefined. It is for these reasons that the height of the atmosphere is considered to be about 400,000 ft, or 76 miles (122 km).

Can you please elaborate how you are "sure" that "we haven't been visited by only one race of aliens, with many different ships"? Is this based on the fact that there are different ships? Just curious. Thanks for the good post!

Kinda makes me think about Buckaroo Banzai's "Oscillation Overthruster".

Maybe they go out of phase with local matter so they can occupy the same space (just 180 degrees out of phase) and essentially pass right-through without any interaction. this should let the craft "slipstream" through the atmosphere similar to being in space vaccuum.

I also remember some CE2 reports where witnesses report a "nullified soundfield" when in close proximity to the device... like a sonic shield (would be great for me when the train goes by at 3AM )

I was making a halfway logical assumption that we've been visited by more than one alien species(if any), because, it is highly probable for aliens to exist...it's also highly probable that many of them have much more advanced technology than we do, and because the universe is too immense for simply 1 species(if any at all) of alien to visit Earth, throughout our history. Ofcourse, the fact that the universe is so...timeless, could also indicate that only 1 species...or no species has visited us. I mean...think of the chances that an alien visit our planet, in this large emptiness filled with billions of plantes. But that's why it's also possible that more than one could have.

I like to speculate a lot. Who knows...it's even highly probable that some species of alien are neighbours and actually refered Earth as a sight-seeing ground through word-of-mouth...or tentacle. LOL

Yes many different ships have been sighted...so that can account for maybe more than one race; but ofcourse, humans have many different aircrafts too...so that byitself doesn't say much. So, I assume, because of the universe's size, the fact that other life has a high chance of existing(with greater technology than ours), and that there may actually be millions, or billions of these beings who poccess greater tech'...it's easy to say that not only one species has been to Earth. Ofcourse, I do not know this as fact...it's just mere speculation.

When I mentioned ultra/infra sound in my previous post...I went a little off topic. I wasn't really refering to the sonic boom one hears when breaking the sound barrier, but to the many cases reported, many of which report that no sound was heard from the vessel. I should have stated that in my post to be more specific. My apologies.

The speed of the UFO might be determined if you theorize the saucer is
one big electrical charge on the move.

I do have a solution for the no sonic boom but I must ask Bill Lyne if
he ever calculated a speed for a saucer.

The boom is negated due to all the positive ion charges around the UFO.
When air the goes around a plane, it crashes back together causing
the boom.
Positive ions repel one another, so they do not crash together to
make a noise.


The speed of a saucer must be determined by the electrical resistance
of the air. Which is normally an insulator but every lecture by Tesla
before 1900 was how static charge moved through the air.
AC is a back and forth movement and is smaller at high oscillations.
Thus, the UFO is actually perhaps a DC machine activated by pulsed
and AC coils.

There is no doubt in my mind we cannot apply our thinking as learned in our clevernous to solve something from somewhere else outside our reality.

Operating within our laws of physics is impossible when excellerating from a dead stop to thousands of miles per hour or turning 90 degrees under high excelleration, avoiding radar signature, pass into and out of water, appearing from no where, dissappearing into no where, playing with aircraft, and showing up close for a fly by with pictures.

To do all those things would mean the craft operates outside our laws of physics and can do as they please. So with that, we can be assured what we think we know is not really true in the sense we know nothing when it comes to the ufo.

They operate within and without our reality. They can travel as we see them without being subjects of our mankind created laws because they made it for the human being to exist in.

I think our reality is made up of realms of layers besides dimensions. The craft could slide out of the physical layer and remain visible but not be subjected to gravity. In the layer it operates from the object reflects light for the craft to be seen but since it is out of the physical layer, atmosphere, rockets, bullets and radar will not affect its manuevering.

The same holds for the abduction. They pull the abductee from our reality of time and space into the astral ethereal where our consciouness operates.

We have evidance of there craft landing in the physical layer. Perhaps these are works from the spiritual or our creators.

They decrease the inertial mass of the air molecules around them to make them superfluid.


Another way is to "blow" air in front of the craft, and move through that moving air, thereby not breaking the local sound barrier.


Or, displace the air in front of the craft behind it via a constant streaming transporter system.


There are other ways...

Considering that I have seen videos where UFO's "shoot" off in one direction at a very high rate of speed why is there not a "Boom" when it goes fast enough to break the sound barrier?

Got any links to some of those videos? I have not seen one that showed that type of movement. I always here about how they buzz around and do things no ordinary craft does, but for some odd reason when we get the video it never seems to live up to the "eyewitness" reports.

So perhaps you could point out a few that we missed here that show what you describe?

The flight characteristics are questionable.. yet discussed by witnesses.

Lyne being one witness to saucer flight in 1953, added a 30 degree
interval switch into the mix found in a NM salvage yard.
Following a CIA truck with a tarp over some wreckage and a recent
report of a crash made him follow the truck.
He made drawings of the items which were high voltage parts,
as seemingly nothing was confidential the salvage yard was told
not to let Bill in again.

If the control of the Cosmos is in the ether, then getting free of the
physics we know must be a part of the phenomena.
However we do theorize of the static shielding that physics has not
told us about.

Did that ever make me think of the six areas of the Atmospheric pressure:

en.wikipedia.org...

Also the terminal velocity of flight:

en.wikipedia.org...

120 mph of drag from a parachute stops free fall.

Is there an ether effect on movement or is it strictly air.
(ether being all else electrical particles and inter atom fields in the air)

Strange how I only read this thread this morning and then a few hours later found this:

Northrop Studying Sonic Boom Remedy

Aviation Week & Space Technology
January 22, 1968

Hawthorne, Calif. --Use of electrical forces to condition the air flowing around an aircraft at supersonic speeds may lower drag, reduce heating and soften sonic boom, Northrop Corp., said here last week.

Although practical application of the technique, assuming research validates it, is quite far in the future, Northrop said its findings in company studies show enough promise to justify government funding of more intensive research, NASA is reportedly interested in the method.

Air molecules ahead of the aircraft would be ionized, probably negatively, through a corona. The nose of the aircraft would be charged to the same negative potential, forming an electrostatic force field which would tend to repel or alter the course of the molecules as the aircraft approached.

Of course they know about it.

All the fliers do now is escort or find lost UFOs that ionize regularly.

How many youtube ufo catchers also have planes going around in circles.

But normal planes won't use ions because of the high voltage.
Heck if the SST had it then no sonic boom and we would still have it.

This technology can never be know and the 1968 article is phony
science too close to the truth and the ionized saucer propulsion
theory have now materialized.

Perhaps that news item got people thinking and connected it with
the saucer UFO in more than one way.


ED: To ionize you need sparks or high potential. And you get both
positive and negative charges. Positive charges are heavier and
not as easy to eliminate. There is no correct science in their
study as they would soon become a ufo surrounded by positive
ions with the proper ejection of electrons.

reports where UFO's go across the sky in what appears to be a matter of seconds but I rarely read that there was a "sonic boom" associated with the sighting.

According to Paul Hill, moving through the atmosphere while creating shock free airflow at supersonic speed should be possible given sufficiently advanced technology.

Most energy lost at supersonic speed arises from the bow shock wave. The shock wave extends outward and backward into a huge cone, so big that it often reaches the human ear and is recognized as a sonic boom.

In subsonic flight the air pressure builds slow enough (from the moving vehicle) to all the air to move aside to let the vehicle pass in a phenomenon called streamline flow. The problem at supersonic speed is one of information. The air does not receive the incremental pressure signal to slow down and move aside..

Now in theory, if you employed a force field which worked on all matter, you could get the air (ahead of your supersonic vehicle) the information in time.. because the force field would have a probable action velocity equal to the speed of light, thus nullifying the supersonic air flow problem.
