Do UFOs/Aliens exist, is Time Travel possible and more...

Re: Do u think UFOs exist

"er, no, there are many confirmed and unconfirmed UFO sightings and encounters."
There isn't any "confirmed" UFO case. Most of the encounters have been proved false by experts. Just think, if an alien community come to our planet, it can only come if it has incredibly incredible technology. Then it can easily show themselves to us, but they didn't. So they try to hide. But if they try to hide (using methods which we don't know), why would they show themselves to us? I can only think one reason for this by an intelligent being - Hide & Seek.
there are hundreds of "confirmed" sightings. just becasue the govt does not want to make it public does not mean that it does not exist.
ok, example : you are in a forest, trying to take a photo of a chimpanzee. you are using an Invisiblity cloak to hide your ass.
suddenly, you need to pee. you cant do it under the cloak, else you'll get pee all over it. you poke yours truly out of the cloak and take a leak. the chimp sees yours truly. you didnt want him to see it, but it *just* happened. luck, chance, whatever.

we are a carbon based life form, that means, carbon forms the most important part of our bodies.
now imagine a creature formed of chlorine, silicon, methane. oxygen would be deadly to it. water would just dissolve its structure (like acids do to us). it would prolly look like a cross between a tortoise and a rock. how would you know its "life"?
Interstellar travel takes a lot of time, but you know, there could be ways to overcome that problem. long living species comes to my mind... cryogenic freezing, bending the laws of physics.. etc."
I told about technologically advanced beings. Even if they're chlorine based or arsenic based, they'd have to use materials present where they live, which is mostly metals and other abundant elements like Hydrogen/helium. They can use it raw, so they have to exploit it, and it creates by-products which can sensed by present-day space machines built by us. Hypothetically, if you have gigantic radio telescopes, and telescopes which 'sees' in different spectrums, you can focus on Earth and sense abnormal activity there. By taking time, I mean travelling time, and not the relative time inside the probe. Cryogenic freezing would just stop biological activities of our bodies (There must be better methods to overcome ageing problems - modifying our body) and not speed up time taken to reach our planet. You don't bend 'Laws of Physics', you follow it every time. There's no absolute law yet, it's more like a collection of overlapping maps. When you hear that black holes bend the laws of physics, they actually don't. They just don't use the classical laws which we're familiar with. We don't know the law. 150 years before, when there wasn't any Theory of Relativity and Quantum Physics, many now-easily-proved things used to 'bend the laws of physics', for us.
ok, listen : the earth has an atmosphere that blocks out most EM radiation. how do you sense something properly when there is a thick atmosphere blocking you? one solution only : close range monitoring. cant do it in space, humans may be watching. so mingle with the humans, who is gonna know? oh wait, i forgot my prosthetic nose... well, i can be lord voldemort today.

"you assume that every planetary life system had started at the same time as ours....
what if the first 3 billion years were not wasted by one celled organisms floating in the ocean? what if the cells became multicellular in just a few million years? those guys could be ruling galaxies..... what if THOSE guys think that theirs is the only life? will they look in other galaxises? our galaxy?"
Well! This can certainly happen, but the probability get lower and lower as you shorten the timeframe, considering the innumerable variables that sets up an intelligent life form.
yes.

"good point "
Yours too! .. and its science, where the quantum world rules. You can be right, I can be right, we both can't be right, or we both can be right at the same time.

replies in red underline.... pls start quoting me. else i have to choose a different color next time

 

[whitestar_999]

just my 2 cents.aliens may exist as probability is there but i seriously doubt they can accidentally reveal themselves so many times.its like saying a quantum computer(which we haven't invented yet btw) is buggy like windows 95 pc.one or two instances is alright but not these so called 10s/100s of ufo encounters in all these years.

about time travel i simply don't think its possible because of various paradoxes.i know scifi depicts time travel & goes around paradoxes by concepts like timelines/alternate universes but still in my opinion it violates the most basic & absolute law of conservation of energy(the only law which can not be broken in my opinion by anyone,god included for those who believe ).

 

[doomgiver]

^^ sort-of right. but see it from this perspective : their technology may not be perfect. hell, even windows 7 crashes some time. given enough time and windows 7 machines, there will come a day that all windows 7 will crash at the same time (even though the probablity of hat happening is close to zero, its finitely probable, hence, it is infinitely improbable)

 

[rajsanand]

First of everybody please first know what is a UFO..UFO stands for Unidentified flying object.
It is nothing but a flying object that has NOT been identified as anything the World knows of...... publicly.

Asking if a UFO exists or saying that you believe in UFO's does not make sense.

The earliest UFO's were flying saucers. No one had seen such a flying object and they were not able to identify it as any of the existing flying objects at that time. So they called it well.........a UFO.

There is a lot of conspiracy theories and even de classified information that USA has been working on Flying saucer technology for more than 100 years.
The UFO' at that time could have been any one of these flying saucers being tested by the USA Defence.

Alien's do exists. The vedas say that there are 50000 humanoid species and all of them do not exist on planet earth. Hence they are alien to the planet earth.

Again an Alient does not have to be a green slimy predator/species kind of a living thing, It can very well be humonoids just like us. All those images and the general idea we have of aliens are from 3rd grade Sci fi movies.

For some reasons hollywood found that such kind of alien movies would sell and they were right.
Learn to separate reality from movies.

Lastly time travel just not possible..Period. You can never ever travel back in time or forward..I don't want to get into that argument, but its logically not possible.
It maybe possible to "look" back in time based on an uproven theory that every thing has a vibration and the vibrations exists forever so if one could tap into that they could see the past. The future only possible if the theory that every thing is pre-determined is true then only its possible to "look" into the future. Otherwise not possible at all only past is possible.

From all other existing theories about reality even the unproven ones(even the parallel universe theory which is only half baked. That is if you dig deep you will find that its logically impossible) one cannot travel in time.

 

[doomgiver]

^^ haha, noobs always post here. its a proven thing.
we should change the topic to : hello, newbs!! enjoy your first shot of trolls and rage here.

Because vedas say, aliens exist? Cool. Then why not to believe Hollywood movies too?

If you read even two posts in this thread, you will realize no one said they need to be movie-like.

The future only possible if the theory that every thing is pre-determined is true then only its possible to "look" into the future. Otherwise not possible at all only past is possible.

I can think of why back travel is not possible, it will make an paradox, but why not future? Any actions taken place in future will not make any difference in then past/current present, so no paradox. What other logic is there?

 

[whitestar_999]

^^in my opinion traveling in time back or forward is not possible because of violation of the most basic & absolute law of conservation of energy.e.g.if a person travel from 21st century to say 25th century then it means after his departure from 21st century the universe of 21st century will lose some energy while after his appearance in 25th century the universe of 25th century would gain energy.this is not possible because total energy of 21st century universe & 25th century universe must be same.i can agree with viewing the past because that does not require any transfer of energy.

check this interesting debate about this topic: Conservation of energy/mass and time travel

 

[whitestar_999]

^^lots of talk but conclusion is no credible proof.to get around the conservation of energy principle & paradoxes alternate universes & timelines were proposed but so far there is no credible way to establish it & in my opinion there never will be.though time travel sound like easy/normal concept to many people but scientifically speaking it is not.even 1 sub-atomic particle traveling through time has massive implications for entire universe let alone a body/organism/piece of equipment.

^^i am an engineer who is reading newspaper for over 2 decades now so you can assume that i know a lot of things about lot of subjects.i have read basics of Einstein's theory of relativity & paradoxes.by scientifically speaking i meant what seems so easy requires solving a very high level of calculus equations which makes 3rd & 4th order differential equations like child's play.space-time physics as well as quantum physics first requires highly complex equations & after that needs highly complex instruments which can apply those equations.its not like someone just propose a set of equations & all is done.just a week ago there is a news in paper about Australian mathematicians proposing a set of equations for faster than light travel by extending theory of relativity to a situation where relative velocity is infinite but they didn't claim that faster than light travel is possible but just that if physicists ever found a way then these equations will help.i am fairly certain that i am the first & probably the only one here who noticed this news in paper & remembered it for its importance so that should give you an idea about my awareness.

P.S.i don't like the terrorist part of your reply & found it offensive so edit your post.

I'm sorry, didn't mean any offence.

 

[whitestar_999]

good to know & i appreciate it. it is just that on internet only words convey our message without any facial expressions to help so it is easy to misinterpret things.still it is my personal opinion that words like terrorist should not be used lightly in today's time.

Adding to the possibility of UFO/Alien/Time_Travel, does the WORMHOLE really exists?
I watched a documentary by Discovery, in which a pilot said he crossed a distance of 130~150 kms in just 3 mins, by passing thro a hole surrounded by vortex of black clouds!

Bermuda Triangle?

^ Exactly. If wormholes are real, then aliens will be real too.
Maybe they could've a technology to travel thro wormholes across the universe(s). These alien sightings may've occured when they travelled somewhere and accidentally sighted by Earthlings.

If they can travel in linear space-time, by this time, our scientists would've found atleast one REAL/ACTUAL non-earthling. Maybe, thats the reason we cant find'em as they skip the light-year travel and directly run thro wormholes. Again, this is just my opinion and am not a scientist (pun intended )

that energy difference may just be the required energy to travel through time... like a travelling fee, if you imagine.
anyhow, shouldnt the total energy of a set of time streams be constant?

er, you seem to be dead set against things that dont appear "normal" to you.
just because it doenst "look" right, it shouldnt be impossible or something.
hell, some people even predicted that no one would buy computers, coz they were too unwieldly.
the thing is, we are doing experiments at such low level of energy, that we are close to zero on finding newer stuff.

we have saturated this "energy band" of physics.

example :

electro-magnetic unification : ~0.5 Mega electron volts <- 100 years ago (maxwell, fermi, etc)
electro-weak unification : ~1 Giga eV <- we are here
gravity-quantum unification : 100+ G eV <- we want to be here

see, there is a huge gap for the gravity-quantum physics unification... our current atom smashers, like the LHC and the tevatron can only do ~17 GeV. thats much lower than the limit of the unification energy. there is still a LOT of work to be done.

well, reading just the news is a totally differnet thing than actually reading the scientific journals and keeping up wihh the current developments in the field.
not dissing your knowledge here.

I watched a documentary by Discovery, in which a pilot said he crossed a distance of 130~150 kms in just 3 mins, by passing thro a hole surrounded by vortex of black clouds!

which shitty show was that? 50 km/min = 1 km/sec = 3000 km/hour = mach 3
easily attainable by the mig-25 "foxbat", even though its a 25 year old fighter. (i freaking LOVE it. its my fav aircraft of its type)

wormholes exist, but not as those kind shown on tv or stuff. they are literally the fabric of the universe pinched together and tied up.

^ Exactly. If wormholes are real, then aliens will be real too.
Maybe they could've a technology to travel thro wormholes across the universe(s). These alien sightings may've occured when they travelled somewhere and accidentally sighted by Earthlings.

no relation at all between the wormholes and aliens. both can exist without either.

^^energy can only be converted never created or destroyed.our universe has same amount of energy today as it had at the beginning & it will have the same energy at any point in future,no way around this.if something ceases to exist from this universe(not destroyed,there is a difference)then it simply means total energy of our universe will decrease which is not possible.

just because neither you nor i are scientists doesn't mean we can't think logically.your logic is based on assumption that there is somehow a way to get around energy conservation principle(no matter what the unified theory research experiment may happen in future this will be the conclusion) but according to me & many others this is simply not possible no matter how much advances we make.like i said this law is considered as absolute & assuming humanity survives billions of years even then this law won't be broken.

reading news is not totally different from actually reading scientific journals because it presents a kind of summary.you missed my point there.everyone who has studied physics in 11th/12th knows about concept of relative velocity.what those australian mathematicians did was propose a set of equation of motions when relative velocity can be infinite(not the actual velocity of an object).also as mathematicians they didn't claimed that faster than light travel is possible but just that if physicists found a way then these equations can be used.now i don't think you need a Phd to understand what i just posted & anyone who has studied & remembered the 11th/12th class physics & theory of relativity can understand the summary.

about that "set of time streams" this is what i am talking about when i say all kinds of things like alternate universes/timelines are proposed to get around energy conservation principle.set of time stream implies that past,present & future are happening simultaneously.again this statement brings its own absurdity.if past,present & future are happening simultaneously then it means that everything is pre-determined & connected because otherwise they won't be connected but if that is true then it is also implied that nothing can be done to change the course of time because doing so will result in dis-connection of past,present & future.

are you aware of the concept of paralel universes and the multiverse?

i didnt say that. you are making it up.
the GUT experiments will drastically alter our universe's perseption, to the point that the laws which we take as granted today, may be broken down and replaced by others (remember newtonian physics? i bet you do)

reading nes is just that, reading news. you miss 90% of the stuff that editors dont think is "cool" or "happening" enough. where is the news of the LHC? of the new 500MW laser that is being used to do fusion research?

about that "set of time streams" this is what i am talking about when i say all kinds of things like alternate universes/timelines are proposed to get around energy conservation principle.set of time stream implies that past,present & future are happening simultaneously.again this statement brings its own absurdity.if past,present & future are happening simultaneously then it means that everything is pre-determined & connected because otherwise they won't be connected but if that is true then it is also implied that nothing can be done to change the course of time because doing so will result in dis-connection of past,present & future.
yes, its all absurd from our current perspective. now bring in aristotle to modern world. he will think this is absurd too. let science take its course, and wait it out.
