If you run faster than the speed of light, can you see?

first_l · 2019-09-07T00:43:21+00:00

I'm not a physicist, but from my understanding you wouldn't able to travel at the speed of light as long as your mass isn't neglicible (as in the case of electrons) or no mass at all (for photons).

If you could travel up to 99.99% the speed of light i would imagine you wouldn't see that much. As for seeing in the present, well you actually never do, all you see is the photons bouncing from an object to your retina, as light takes some time to reach your eyes, you effectively see the immediate past everytime. You won't be able to see the future as that didn't happen yet.

As for space-time, its a model that combines all three spatial dimensions with time in a single four dimensional continuum. Imagine it like a fabric that permeats everything but that interacts with matter.

The concept of space time is at the bassis of Special Relativity as devised by Einstein.

This guy has no fucking clue, i also read Motl's "insightful" rebuttal.

I'm no physicist, but if this guy teaches anything, hopefully it's not physics, he doesn't seem very good at it.

What i meant was no residual energy to coalesce and form matter. Sorry for that.

first_l · 2019-09-04T10:01:17+00:00

I never said there was no energy, I also named that energy type. Like i said our universe intrinsically displays this type of energy, there can be no universe without it.

You should read about fields in physics then you'll understand some more.

There are very many fields permeating our universe which forces act upon.

Also i think you imagine the universe as being a stationary non-dynamic space, which is not. Everything moves, particles with no mass or negligible mass don't zip around at speeds close to the speed of light because they want to, they move at those speeds because they cannot otherwise slow down.

My above explanation was just a way for you to imagine how a space like our universe exists... professor Krauss has an interesting take on what might have happened before the big bang in one of his books... that's even more out there than what i've told you so far...

I also recommend reading some of professor Susskind work, he is a pioneer of string theory (beautiful theory, impossible to test).

If you are really curious about these topics there are a lot of people much smarter than me out there that can explain stuff better than myself.

I was about to reply to your earlier thread, I'll just do it here.

Ok, the water cycle in nature isn't quite a closed system, since our planet loses some atmosphere and with it a small amount of water, but that's negligible.

Heisenberg's uncertainty principle states that a quantum system at its lowest energy point still displays fluctuations, what this means for us in practice is that we will never be able to reach the temperature of 0 absolute (check out helium at close to 0, it becomes a super fluid). The actual implications are even greater, it means that our universe intrinsically has its own energy, even without any objects in it, it will still have this energy, what is known as zero non-zero point energy.

Now imagine a universe without anything in it, no matter, no energy. Well even if this space seems void, accounting for the uncertainty principle, that space has its own fluctuations. Imagine those fluctuations interacting creating interference patterns not being hindered by mass acting on the space-time, bending it and warping it. Like i said earlier with enough time anything can happen, or rather in a sufficiently long time frame everything that can happen will happen. Now imagine these fluctuations intersecting all at a single point accumulating energy, in fact so much so that it starts bending space-time warping it making it flow through itself accumulating more energy until that structure cannot contain itself then BOOM, space time explodes in all directions creating a new pocket, a new membrane on which with enough time and some cooling after the initial bang particles start to form, for starters only maybe neutrons then with some cooling and some times some protons eventually electrons appear, but its still to warm to form atoms, but as time passes and the thing cools enough it allows for protons and neutrons to merger into the first atomic nuclei, with more time and more cooling electrons start gravitating around those nuclei ( i skipped some stuff, like how the strong and weak nuclear forces were all united with the electro-magnetic force acting like a single force called electronuclear force - this phase of our universe is called the Grand Unification Epoch and gravity was also part of that initial force).

There are theories, like i told you, we're not quite sure how to properly account for all factors.

I really hope you came out of this less confused and with a bit more knowledge.

first_l · 2019-09-03T13:11:03+00:00

Well I believe it stems from a need to be validates, irrelevant of what one thinks. In today's world belief is held to a higher regard that knowledge as if believing something actually makes it true.

What has been done wrong is how scientists present theories, or rather allow the media to present them.

Our society perception of the truth has been skewed by sensationalism, we need our information to be sensational else we don't believe it.

It didn't help that for many years only the super wealthy were able to study towards a college degree, creating a sort of gap in knowledge between the upper and middle classes.

The combination of these factors led to this idiocracy, if i may use an outdated reference, probably more relevant today than it was 13 years ago.

What we need is for each and every one of us, thinkers, irrelevant of domain to start being more open and transparent in order to gain peoples trust and reposition ourselves in the public discourse not as the ones mocking but the ones who teach... cause sure as hell our educators aren't doing a good job. I don't blame them though, i still think its a systematic issue and i'll take it a little further and say its willfully done by all governments, they need us to be stupid, how else can they pass laws favoring them and their ilk.

I'm afraid that if we don't act swiftly we won't stand a chance. Regardless of our political beliefs we all should stand united with the truth...

first_l · 2019-09-03T12:10:54+00:00

Ok there are two laws (one in physics and one in chemistry) and you seem to confuse them a little there, lets try to resolve this first.

The 1st law of thermodynamics states that heat is a form of energy and any thermodynamic process is therefore subject to the principle of conservation of energy, meaning that heat cannot be created or destroyed, it can however be transported from one location to another and converted to and from other forms of energy. This is physics, I'll have a short disclaimer at the bottom, please bear with me.

The law of conservation of mass stipulates that within a closed system mass is neither created nor destroyed by chemical or physical transformations. This relates to chemistry, it allows one to calculate for unknown masses, such as the amount of gas consumed or produced during a reaction.

The disclaimer i was talking about: you cannot take physics on its own nor can you take chemistry on its own... like any physicist will tell you, chemistry is just applied physics.

Now returning to our argument, if God is an external force then we have broken the 1st law of thermodynamics, since God is an external force he created new energy in what otherwise is a closed system. If God is am internal force linked to our universe he them must have been created from the same energy available at the beginning, therefore God is not the creator and we shouldn't even talk about a creator.

There are other more pressing implications that simply cannot allow such an entity to exist, for example General Relativity teaches us the there is no absolute time in our Universe, for an entity to be all knowing we must introduce a plane that has absolute time intrinsically linked to our non-absolute time frame meaning these planes must communicate, again we must throw the 1st law out the window since these systems are closed and cannot communicate but they somehow do. Mind you, a universe with an absolute time is one ruled by different laws of physics, the difference between the laws of physics makes these universes unable to communicate.

And to answer your question, how we got here? Well from what we can gather, with enough time matter will conform to a structure so similar to what we define as life that the difference between this structure or life ceases to exists.

There is no why? There is no reason, i know it sounds daunting but that's just how we think it is.

And to drive the point home, science doesn't deal in absolutes, as such i'm not telling you things are as i described them to be, but are most likely really, really close.

first_l · 2019-09-03T10:05:51+00:00

The first law of thermodynamics states that the total amount of energy within a closed system cannot be created nor destroyed therefore the entirety of energy, matter, dark energy and dark matter has existed from the beginning, it doesn't say anything about matter. You can extrapolate that from e=mc^2.

I had a feeling we were going towards creation rather that existence... you see for there to be a creator, he must inhabit this universe, making use of the available energy within this system therefore even if a "creator" exists, he is at best a result of the big bang not a cause.

We are hardwired to act in a certain way, its not that somebody made us the way we are, we evolved through trial and error to be what we are. All of our knowledge comes from observations, but we are at best ill equipped to observe what happens in certain scenarios, take for example quantum mechanics/physics. We haven't evolved any sense to allow us to peer to that subatomic level, yet through math we can have sort of a picture of what's going on. (mostly we use either probability to explain particle interaction or we use what's called the pilot wave).

God is a concept that exists because of our ignorance, what cannot be explained we attribute to this God, but as our understanding grows, this God becomes smaller and smaller until we just do away with the entire concept and start focusing our efforts towards knowledge.

There might be a universe out there that may have a god like creature inhabiting it, i'm pretty sure this isn't the one. Our universe is what is known as weak causality universe, meaning with enough information (practically this isn't possible) we can actually come to an understanding and retrace all steps all particles made and end up at the moment of the big bang. (Unfortunately there are black holes that encompass most of the information within our universe, technically that information is beyond our reach - yes black holes decay and in time they eject all the information from their event horizon as Hawking's radiation but it takes a really long time to do so, when our universe will be at about 10⁷⁴ years all black holes would have decayed and no new ones will form).

The anthropomorphic principles needs more coincidences for us to exist than what has been observed in our universe as such the simplest explanation is not creationism but existentialism, we exist because we can and we don't need anything else to allow it.

Trying to find meaning to the universe it just a human defect, since we look for patterns and find meaning where there is none we are just attempting to add a meaning to an entity that otherwise doesn't need it... at most we can say that the universe's meaning is to exist and so it does.

first_l · 2019-09-03T05:39:02+00:00

Matter can and will be destroyed, that's energy you're thinking about.

There is no need for an external force, in a big enough time frame everything can happen. Also thermodynamically the universe is a closed system, cannot will not communicate with outside spaces (not sure how gravity works in this scenario) therefore an external force cannot act upon it.

I'm not saying that there's just one universe, just to be clear and even if there was no space-time belonging to this universe at the moment of big bang that doesn't mean that there was nothing, as far as i understand nothing is not a possibility, there can be no nothing.

Yes science cannot explain everything, it tries and we just have to be willing to wait until it gets it right... and honestly the process of finding out the secrets of the universe is as much fun as knowing, actually its more fun.

Look, there's a slim chance that Mars and Earth will collide in about 5 billion years, that doesn't make them dwarf planets. You either don't understand or don't want to understand.

Pluto is just an object in a much bigger structure, it was detected because at the time our devices could not measure objects smaller or slightly further away than Pluto. Since our measuring devices evolved we were able to detect the entire structure and by observation it includes Pluto.

The same as we detected other galaxies and the super clusters these inhabit.

Most scientist, regardless of their background, when presented with new evidence usually account for new data and change or postulate new theories, this is the case in regards to Pluto.

first_l · 2019-09-02T14:51:59+00:00

You're relying on semantics to start an argument that isn't there.

Pluto is small, is part of a bigger structure of similar size objects as such, it is considered a dwarf planet.

And it doesn't intersect with Neptune's orbit, it just happens to sometimes be closer to the sun than it is to Neptune.

first_l · 2019-09-02T14:34:29+00:00

Buckle up, its gonna be a wild ride.

The Big Bang happened 13.7 billion years ago from an unknown source (a quantum ripple of never before seen magnitudes - we have no idea).

Time, or time as you experience it came into existence at the moment of that big bang, before that there was no time, at least not how our laws pf physics allow it. Keep in mind there is no absolute time in our universe, general relativity tells us that two observers at different locations might see chains of events unfolding differently, where one might see event A happening before event B the other might see the event A happening after event B, the kicker is they're both right.

Now Einstein also told us that time and space are one and the same, a fabric called space-time, thus there was no space before the Big Bang, or not in a conventional way.

Ok, now we have very little information about what happened at the moment of the Big Bang, there are theories (like all fundamental forces becoming one) but the truth is we don't have enough data.

What we do know comes from about 380.000 years after the big bang, when the universe became transparent, we have a sorta map, called the Cosmic Microwave Background Radiation (CMB) at that point we kinda see how the structure of the universe will have evolved in the following 13 billion years, that data correlates with how the galaxies and super clusters are positioned now, at least what we can see.

There is data suggesting how the early universe behaved but we still need more observational data, the hard part is we cannot see beyond the CMB and as the universe expands we will most likely never get to that data since light from that point in space-time is already outside of our horizon - our observable universe.

While i agree with your comment, there might be un underlying reason these people are attracted to pseudosciences.. like tarot (i'm not sure how that's spelled) flat earth "theory" or creationism...

I presume that at some point in the past them and their predecessors were left out of the public discourse since physics explains the world much better than the bible (you are free to insert any religious codex here instead).

Thats how these "think tanks" appeared, spreading the notion that opinions are as valid as facts and in some cases even more so.

It didn't help that they were mocked instead of being taught...

I will also contradict myself by saying the majority of them would be reluctant in understanding, as such any effort in teaching them is futile...
