A Unified Theory of Forces (10 of 15)

[Graham6762]

If CERN kills me I am going to be so fucking mad.

[remoraid7]

In fact, the beam of light would still travel past you at exactly the speed of light, c= 6x10^8ms-1.. Weirdly your speed makes absolutely no difference to how fast light travel from your point of view.. That's because, time for you had slowed down with reference to the source of light.. And your entire body and brain and everything that is traveling with you slows down..

[remoraid7]

In einstein's theory of special relativity he states that the speed of light will always be the same no matter how fast you are travelling.. Say you are running at 99.99999% the speed of light, and a powerful laser light beam overtakes you.. In classical physics, you should be able to see the beam of light overtake you slowly like how a 100kph car overtakes a 99.99999kph car.. However, Einstein says that this is NOT the case..

[allthingsmmm]

i think increasing the density of atoms=more force.. just like the belief of the center of a black hole being super dense.

[allthingsmmm]

my point was i think it may be these common forces positive and negative, pushing and pulling forces that cause things to drop to the earth, because of the particular conditions of these forces on planet ie earth.. earth acting like an electromagnet, and objects being held within the earths electromagnetic field. where as in space they call this 0 gravity bc there is no earth acting as a spinning electromagnet, but there would be the pull of nearby electromagnets.

[allthingsmmm]

hmmmm.. everything has a force.. atoms have positive protons and negative electrons, everything is made up of these (and smaller particles). i was saying the way these forces interact is the same as the way planets interect.. i wasn't excluding anything or object.

[allthingsmmm]

i think everything is electromagnetism.. and that gravity doesn't really exist. planets have poles like a magnet and spin. this i believe like a generator.. a planet or an atom creates the force that holds us to the planet, atoms together and planets in the solar system. aswell all weather related forces (energy) like wind, waves, ect.. are a result of the planet spinning on it's poles and coming in contact with the celestial bodies spinning on their poles and being attracted and repelled.

[conkel29692]

@allthingsmmm that theory doesn't hold together at all, gravity is not exclusive to planets or other celestial beings, everything with mass has gravitational force, the more massive the object, the more gravitational force it 'produces'. Also it's a well established fact that gravity and electromagnetism are two completely separate forces, where as electromagnetism is purely a force, gravity also exists within the space-time, warping it and slowing it down, electromagnetism can in no way do this

[grizzzlyjoe]

A Theory of Everything: You're born, you die ... what happens in between is EVERYTHING.

[magicyte]

I'd say instantaneous travel is just as laughable as time travel. since in order to just appear somwhere else...mass and energy rules would not apply...thus in our existance and universe...time travel and instant travel is just not posible.

[magicyte]

Time travel is not nor ever will be possible. It's illogical. Travelling at instant speed might be more plausible...faster than that...no. We don't even know the speed of something that is near instant. The largest number known to man is still not fast enough to be instantaneous. We can go 100000000000000000000000000000­0000000000000mph....aand still not travel fast enough to appear somewhere instantaneously. Time travel is a joke.

[fleminem1]

@magicyte pessimism never achieved anything

[magicyte]

@fleminem1 Way to make an arguement.

[magicyte]

@fleminem1 You go ahead and make me believe then. Feel free to explain to me how light is the absolute fastest thing in the universe...I wonder if you know what neutrinos are? Helluva lo more potent than photons. We know nothing in the scheme of things. We'll find many many  more things that travel faster than neutrinos still...why not improve our own daily lives instead of searching for fantastic realities to replace our own?

[fleminem1]

@magicyte Lol 'more potent'? that means nothing, what do neutrinos have to do with time travel?. I agree that our priority should be resolving problems in day to day life, but theoretical physics and scientific speculation can go along way towards that. Read Michio Kaku's 'Physics of the impossibe' If you told someone that lived 500 years ago that we would cruise along the skies in massive metal vehicles hundreds of times the weight of air they would have called you nuts. No time for pessemists.

[Skindoggiedog]

@magicyte - "The largest number known to man is still not fast enough"

What is the largest number known to man, mate?

[magicyte]

@Skindoggiedog A misnomer...the number isn't known since it's impossible to fathom. That was my point. Even teleportation has time measurement. Sceience has never reached a limit in anything yet. Since to reach a limit would admit achieving the fastest speed possible. Once a limit is set that's it. Science won't have meaning after that. Time travel is just as ludricrous as a black hole being more than a swirl of water in a sink drain.

[magicyte]

@Skindoggiedog You've heard of going forward in reverse right? It's illogical to go so fast that others around you begin to walk backwards. Would be more sensible to argue something could travel so fast that others around it would appear to slow down close to a stop...hell...even to an absolute stop for the hell of it. Anything beyond that is just rediculous. Better to leave understanding to whoever created the universe.

[DerangederX]

@magicyte Actually, They have created a time machine. Using lasers to push subatomic particles beyond the speed of light through a medium they can actually send bits of matter back in time. The machine has been run without introducing partials into it. Yet some appeared, because they were put into it then next day. If you actually did some research you would know this. However, since you think someone created the universe, you probably are not big on learning.

[vantarinitel]

@DerangederX That sounds totally awesome! Eh, where did you get that info? (Googling 'time travel' won't get anything legit...)

[Greorgy]

why does this asshat keep smiling?

[TheKkronic420]

@Greorgy that guy has a Ph.D., his job is to present material to the general public so they can become more informed. a smile goes along way when describing something that requires intellect to to be understood.

[GrowlingVocals]

does the mass acquired by an object from speed affect its gravitational properties?

i mean if you make the earth move much faster will it make the gravitation become stronger as well since energy is mass?

answer please :)

[baritonick]

@GrowlingVocals

Yes. You would have to be traveling at a high percentage of the speed of light in order for that to have any measurable effect, however. But, the mass of the object would increase, and its gravitational effect accordingly.

[GrowlingVocals]

@baritonick didnt know that,thanks!

[TaNgLeD2121]

what if you exelerated an electron past the speed of light?? would it no longer exist? is it even possible with the lhc

[sidewaysfcs0718]

u cant ....the speed of light is the speed limit

in order to accelerate an electron to the speed of light u would need infinite energy ....and u cant get it faster than light ...hell ..u cant get it to the speed of light

u can get it closer and closer ...99.999999999999999999999999­9999999% ...but u will never get it to 100% ..

[TaNgLeD2121]

@sidewaysfcs0718 .... i understand that..... i guess i phrased it wrong,.... what if we could accelerate matter to the speed of light....... i understand that we cannot do this yet and we have no conclusive theory of what might happen if time didnt exist, i was just speculating...... its a mind boggling thought tho :)

[sidewaysfcs0718]

@TaNgLeD2121

no its a good question

and there is an answer

since u need infinite energy in order to accelerate something to light speed , and energy is mass ...u would get an object with infinite mass wich would collapse the entire univer in on itself , since the more mass the more beinding in space , infinite mass would bring the universe back to a big bang ...

the end :)

the lhc makes protons 7000 times heavier ...but thats not nearly enough to affect anything at all...

[TheNewRiflemanBob]

Where can I get the thing at 1:41 ?

[RvNYC]

Why isn't dark energy considered a fifth fundamental force? And if it is, doesn't it pretty much send the GUTS folks back to the drawing board. I mean they entirely missed a fundamental force which seems to make up 3/4s of the universe. Oops.

[wowsa0]

Why should it be a fifth force?

[RvNYC]

@wowsa0

Well, why not? It is as of yet undefined expept for it "causes" rapid expansion. It is not mediated by the known force carriers. Why couldn't it represent a new force or class of forces.

[wowsa0]

Well the question "Why couldn't it be...?" Is a bit different to "Why isn't it...?" which was in you're initial post. I don't really know anything detailed about dark energy, I think ideally you'd need an advanced physics degree for that, so for all I know it "could" be, but from what I do know about it I don't know why it necessarily "should" be. Hope that makes sense.

[sidewaysfcs0718]

we never missed it ..we just cat find a boson that mediates it ..therefore we cant explore it ...YET.

[RvNYC]

@sidewaysfcs0718

Good answer. BUT you cant deny it is something like a huge leap of faith to assume you can get a theory of everything when up to 96% of what is, is unknown. Simply the 4 fundmental forces are based on observations of only 4% of all that is. So maybe we're no more near a basic understanding, a G.U.T., than the Greeks; and yes, yet!

[sidewaysfcs0718]

faith is such an ugly word .

so far every particle predicted by the standard model exists :D except the higgs :)

then again the higgs mechanism was proposed just to solve the mass problem of the SM ..meh ...doesnt really matter if we find it or not ...the standard model is still correct ..the mass part is just ...incomplete :)

[sidewaysfcs0718]

dark energy is a component to gravity

dark energy doesnt corespond to a particle....its just part of gravity ...gravity has a small repulsive component wich only is important at large distances ...like thousands of light years...

[GeorgesBarras]

Scietists are like clergy to me, like shamen - they are the wisdom keepers of the 21st century community, they are the percievers of truth. Long may it continue.

[sidewaysfcs0718]

would use the word "clergy" in science ...kinda reminds ppl of the ignorance of religion :|

althow shamen is nice ..all about nature :D

[sinwow33]

You seem to be missing the point. For example if scientists had not dicovered QED then you would have no electronic engineers as there would be no electronics. Engineers need to know the parameters in which they can work and these parameters were defined by scientists. Both roles are important but to suggest that you do not need scientists is plain crazy. Also if physicists do discover a universal theory that does not mean that we know everything and that the theory works in all cases.

[sinwow33]

haha engineers rely on physics if it was not for us working everything out then you would not have a job in the first place. Engineers do not care how things work they only need to know that they work and without physics they would not know how if things worked.

[TheAmericanPageant]

Engineers don't just get a manual on how to create something from scientist, because if that was the case I assure you that anyone can be an engineer if they can follow instructions.

[jamesstone123]

"Engineers are concerned with developing economical and safe solutions to practical problems, by applying mathematics and scientific knowledge while considering technical constraints"

Wikipedia Quote.

They apply the knowledge of mathematicians and scientists, whilst considering the technical considerations that science leaves out, such as size and costs restraints.

They arent the ones with the theories man.

[risecolt]

so weird... was looking for youtube.... found on google a page called... youlube.... lube? dude... no thanx

[judybug7779]

outdated! currently the weak strong and electromag foces are combined in a generally accepted theory (gauge theory). Some theories are succesful at expressing gravity as a gauge force such as non-comutable geometry (AB not= BA).

[diogenden]

not really. you'r talking bout a theory. the electroweak force was actually merged in an experiment. But human kind hasn't yet merged the electroweak and strong forces together. Only on the paper. So it's not outdated. He's talking about things that have been prooven. Otherwise he would tell us about string theory.

[spraitazz]

I love these series! So educating.

[risecolt]

I suggest you look for youtube files about: Michio Kaku. He is a Japanese Physicist, talks about the theory of everything. Enjoy the jurney!

[jonnybosch1988]

Yesss! Michio Kaku is a legend. tis all good stuff...is a shame only 14000 ppl have seen this

[Petelecaster]

@spraitazz

The beautiful part is that it just touches what is available for us to learn.

This video is very educating while still being extremely general.

[BrightSoul80]

Theory of everything, yeah! I'd like to live long enough to see that day.

[neomaster911]

what would happen to all our physicists? you know?

[harshvgaus]

they will be laid off, hehehe, while engineers like me will have a lot to do.

[Geosondaman]

You're just ignorant, physicists are important, as important as engineers and even more so in some cases. We are at the frontiers of science, you engineers use the science we make to make applications. Who relies on who?

[TheAlexander356]

@BrightSoul80 I'll try to see to it that that happens bud ;D

[raydredX]

@BrightSoul80 I wonder if we'll think we have one just to find out some sort of inconsistency.
