The power to propel us to the stars

[Strathos]

As a hypothetical, I am traveling in a spacecraft circling the earth traveling at a speed of 1,000 miles an hour and I shine a flashlight out a front window of the spacecraft; the light would travel 1,000 mph + 186,000 mph

(186,000 mph)+1,000 mph=187,000 mph

The light leaving that spacecraft will be traveling faster than the known speed of light, proving that light can travel faster than 186,000 mph

No it wouldn't. Relativity.

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).

 

[Kaon]

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 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.

 

[Kaon]

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).

The power to propel us to the stars

Can we reach the stars and beyond?

The answer is YES!!

Getting humans into outer space is not the problem. Humans have already walked on the moon. The problem with space travel is the vast distance between our solar system and the nearest one to us. The problem is in the speed needed to reach these far-off places in a reasonable time frame. The solution to the has been right in front of us.

Take for example someone at the front of a train traveling 100 MPH. If the person fires a bullet out ahead of the trail that travels at 300 MPH if you clocked the speed of this bullet it would clock at 400 MPH, not 300.

The same principle could be applied to space travel. The craft would have multiple propulsion engines. When the first one is fired it propels to craft to a speed of 1,000 MPH. When the second propulsion engine is fired (with the same propulsion force as the first), the craft is now traveling at a speed of 1,000+1,000 equaling a speed of 2,000 MPH.

If you continue firing these engines your speed increases with each engine burn. The ultimate speed you reach depends on how many bursts your engines can provide With one burst at a time you could reach the speed of light and beyond.

Or so it seemed~~~~~~~~

Now, some time later I discarded the above idea, a spacecraft could not contain enough fuel to propel us to distant stars.

Then an actual solution came to mind.

We use the force of gravity to pull us to wherever we want to go. Magnify the force of gravity using the gravity pull of galaxies channeling that pull in a narrow band multiply the pulling force of gravity exponentially to a limitless speed.

It could be done~~~

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

 

[Yttrium]

The light shinning out from my flashlight is traveling at the speed of light plus the speed of the station.

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
