Washington (CNN)A group of US senators, including the vice chair of the Senate Intelligence committee, received a classified briefing Wednesday about a series of reported encounters by the US Navy with unidentified aircraft, according to a congressional aide.

No it won't because at high velocities vector addition according to Galilean Relativity doesn't apply.
The correct velocity equation according to Special Relativity where the spacecraft and the light beam are in the same direction is given by the equation.
u = (u'+v)/(1+u'v/c²)
Here u' = c is the velocity of light beam, v can be any value for the spacecraft <c.
Plugging in the values;
u =(c+v)/(1 +cv/c²) = c(c+v)/(c+v) = c.
Hence to an "outside" observer the light beam still remains at a velocity c irrespective of the velocity of the spacecraft.

Ok, so far, you equate the following--
u = (u'+v)/(1+u'v/c²)
u =(c+v)/(1 +cv/c²) = c(c+v)/(c+v) = c.


above you have “u” described as

u =(c+v)/(1 +cv/c²) = c(c+v)/(c+v) = c.

therefore u=c
velocity=v
constant (value not stated but constant))=c

Therefore; we end up with=
(constant + velocity)
Divided by--- 1+(constant + velocity) divided by one (1) + =

Bla, bla, bla~~~~~There is no equation that can quantify the speed of “light”

Therefore; the concept was intriguing to contemplate; we all know there are many sources of light; i.e. coming from our fireplace, lamp, match or the stars. I seriously do not believe we can calculate the speed of any source of light.

Just my opinion
As far as I can see
Then again, maybe the speed of light is constant-?

That viewpoint is most likely why they have decided to not reveal themselves. When the day comes when no one has the same views you have; then maybe they may say hello.

It isn't a viewpoint. Do humans kill their own, trash their own planet, rape/torture and judge each other based on superficial things?


If they are hidden, that means they have something to hide. If you follow sci-fi lore, only malevolent beings from other planets visit pre-warp planets; if they were transparent, honest and truthful they wouldn't even visit our planet until we stopped killing each other for fun, using resources to exploit each other, cease fighting wars for currency, and spend our time eventually progressing to a technological base (instead of degeneracy).

That is if you actually believe in aliens...

Heh, well not really in terms of relativity. Your reference frame has just shifted (1000 mph)(t) miles from the reference frame of the light - which is alleged to be the same in all reference frames based on electromagnetism (not relativity).

The speed of light (one classical way to calculate it) is the product of electric and magnetic constants. It can be measured based on determining field interactions in a lab - and tends to always be "c" in the medium of a vacuum.

The last part is important; photons responds to media - more so than other fundamental particles like neutrinos (which can pass through a lightyear of lead before interacting with matter.)

What the equation tells you is that the speed of light is independent of the velocity of the source.
It doesn't matter what the source is can be fireplace, lamp, match or a star.
One doesn't have to explicitly measure the speed of light to determine its constancy as interferometers will detect destructive interference patterns in recombined light beams should the speed of light of the initial split beams which travel in different directions vary.

There is a caveat however; as interferometers become increasing more sensitive, the speed of light might vary at very small scales at the quantum level.

Oh wise One, I was not present nor have I read about such an observation.
Please, continue to share your wisdom here so that I & others may glean a glimmer from it.
I ask you as a fellow human being.,..,.,.,.,./\
no animosity intended or implied
Please, share your knowledge with us all -

I don't believe electromagnetism is relative to gravity, do you-?

I honestly can't tell if you are being sarcastic - to no fault of your own.

Either way, if you or anyone else is actually interested you can PM me or make another thread. We don't have to agree; a thread like this isn't exactly the right place, however, to talk about electroweak theory in depth.

If you think gravity is what it is known to be today, then EM and gravity categorically disconnect. Indeed, it's the last fundamental force we cannot unify (we can unify strong and electroweak).

I am not being sarcastic
Matter and electromagnet waves are two separate things.
Should you create a thread about this, please find me, give me a link
I for one am interested in this topic

Remember, we have unified electromagnetic force (photon) with the weak force (neutrinos). The neutrinos have mass, which is why they are so interesting with respect to unification. Their masses also spontaneously change (mixing), which has its own quantum mechanical implications.

We call "matter" waves and general waves fields. There are scalar fields and vector fields; mass would be a scalar field and E&M are vector fields.

I won't likely start a thread, but if I do or if there is a good debate/discussion, then I will tag you.

Uh, no. You really need to come into the 20th century (the one that ended 19 years ago).

We are, so far, limited by the speed of light. There are, however, several ideas about avoiding that limitation. We will need a lot more knowledge before we can accomplish that.

Basing your beliefs upon your own incredulity may be satisfying, but it's not very smart. Fortunately, neither the universe, nor the scientific community need to have any concern for your opinion on the matter.

I honestly believe you know what you are talking about when I in fact know I don’t.

So please, just answer this simple question---

As a hypothetical;
I am traveling in the space station and I am sitting at a window that is facing forwards. The station is traveling at 1,000 miles a hour; I shine the flashlight out the window in front. The flashlight & I are traveling at a speed of 1,000 mph. The light shinning out from my flashlight is traveling at the speed of light plus the speed of the station.
Station 1,000 mph+light speed 186,000mps =187,060mph

Nope. It's going at the speed of light (assuming you're shining it into the vacuum of space). Every observer, no matter what their velocity, sees the light traveling at the speed of light relative to them. Freaky, but true.

I had to look it up; reveling my obvious stupidity

Noun
incredulity (usually uncountable, plural incredulities)
Unwillingness or inability to believe; doubt about the truth or verisimilitude of something; disbelief.
(rare) Religious disbelief, lack of faith.


believe me, you are wrong, I do believe; it just may not be what you believe
