Universe expanding ??
    #23889741 - 12/03/16 06:16 AM (7 years, 1 month ago)

We all know that galaxies are moving away from each other and expanding.

What you might not know is that the expansion process isn't slowing down...... but actually accelerating !!

That right there and then dis validates Big Bang theory. Some mysterious force is pulling us apart!! :gethigh:

The current theory is that Dark energy is responsible for the expansion.  Whatever that means.

they are now straying away from the belief that we are accelerating in light of having more data to analyze speed from.

exactly a lot of the "new physics" not just string theory is not really testable
science has taken a strange turn in physics and Astronomy
meanwhile Biology a previously 'softer science' is the one making the more amazing discoveries
that have real consequences

CRISPR will change the world as we know it
add in more intelligent automation  and if 'we' survive
a bit longer, the world as we know it, will feel quite different

personally i think big bang is only half the story.  i believe we also have another universe that moves through space time backwards and collapsing.  its point of impact would become our big bang.  to me it doesn't make sense that the big bang just happened.

Warp drive.

CRISPR and other biochemical stuff is pretty cool nowadays, what with everyone wanting to fix the big C. That leaves us with two more Cs to fix (cars, cake) before we get rid of the top three killers in the developed world.

But at the same time, some of the stuff physicists, and physical chemists, and computational people are doing is super cool. They're figuring out cheat codes to reality. I'd rather have a quantum linked particle computer that I can connect to from everywhere and a spaceship than a cancer cure. Maybe a CuO-nanohexagon doped battery anode in my phone that extends battery life 2x (happen to be writing a paper on). Cancer cure will extend my life five, maybe ten years, counting lying in bed, but I'd get a whole lot more living done if I could have some of the wilder dreams of physicists be a reality.

if you pass the speed of light it means that the light which you observe now actually moved there before.

lets say you pass the speed of light by the equivalent of a second, you're watching the light of a second ago.

Maybe in a couple thousand years... maybe more... maybe less... maybe never. :smile:

Yeah, that's right.  Light defines time.  If you think about it, everything in time exists based upon the propagation of light.  If you go faster than a light beam, you could create an effect before a cause.

Since no one knows.

I imagine one day after trillions of years of expansion the universe will slow down and begin to retract on itself creating a secondary big bag once all matter coalesces to a central point.

That or it'll keep expanding forever until true entropy is reached.

well, if something like say a black hole could accelerate matter faster than light then the matter would be tossed backwards in time where it would end up back at the big bang.

There are three theories about what will happen, if everything eventually slows down and stops expanding it will be pulled back together by gravity into another singularity (Big Crunch)

Everything keeps expanding, all the stars die and everything cools off ( big freeze)

The expansion rate continues to grow exponentially via dark energy until eventually the expansion approaching light speed you would be able to see less and less of space since everything is moving away from everything else. Eventually everything you see would be red shifted until the point you couldn't see your own feet and all the atoms of everything in the universe are torn apart (big rip)

I like to believe in the first, the Big Crunch, because it would be followed by another Big Bang and everything reborn.  There could have been errors in the original expansion data.

Apparently gravity could be an emergent property in the same way as temperature is, and cosmic inflation could be disproven. :shrug:

Quote:

"His suggestion is that gravity isn't a fundamental force of nature at all, but rather an emergent phenomenon - just like temperature is an emergent phenomenon that arises from the movement of microscopic particles.

In other words, gravity is a side effect, not the cause, of what's happening in the Universe."

When we first noticed the cosmic microwave background radiation that is how we concluded the universe is expanding as the light in all directions is uniformly moving away from us. It is shifting in spectrum which happens as light travels, it slowly loses energy. If it's moving away in all directions then that means if you were to go backwards in time it would all coalesce to a single point. That point is what we call the big bang. The big bang theory directly came from the observation that the universe is expanding so not only does the expansion validate it, but it would not exist without it. When you think about how little we know about the universe though it seems very premature to conclude we truly even are expanding much less that you can draw this current observation all the way back to the literal beginning of time.

In Quantum physics it does, the speed of light is directly correlated with the passage of time.

Quote:

In physics, the Planck time (tP) is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length, approximately 5.39 × 10-44 s.[1] The unit is named after Max Planck, who was the first to propose it.

IF you haven't already subscribe to the PBS spacetime channel. Talks about this in depth and apparently the universe will expand forever there will never be a big crunch like has been speculated before. And apparently it was this discovery that led to the discovery of dark matter which is in fact not even matter at all......

If everything keeps expanding the big freeze would be the most likely end, but just a shitty way for the universe to go out, all that wonder just fizzling out.

Speaking of dark matter and mush, had one of those higher level trips where you're exploring the universe and true or not on one particular trip I was shown a cool theory about dark matter. In the trip dark matter was like the mycelial network from which all physical matter came. At the time it blew my mind, being that physical matter (what you can see) only makes up a small percentage ,  just like the fruiting bodies. You can't see the myc network being under ground on a different plane where it isn't visible though it makes up the majority.  Especially later looking at pics of the cosmic web, the galaxies look just like hyphal knots.  May sound dumb but at the time my mind was blown lol.

Not at all man these stories of becoming the universe are all too common and I believe it's like has been said by Alan Watts which in our physical form are nothing more than an aperture that allows the universe to look back on itself.

I myself have had an amazing experience on a 7 gram trip maybe the best experience of my life ,and I've been married before!! My trip seem custom designed around my persona and desires etc. The trip was me somehow discovering something amazing that was connected to Eric Claptons From the Cradle Album, Einsteins theory of relativity and other stuff that was lost from memory but meant that I no longer needed to communicate verbally to anyone as they could just read thought throughout time and space and would know of the happening that was which meant infinite abundance for all. No shitty jobs no president, no jobs really at all everyone was free to live their lives and be happy and not have to worry about struggle...I was so sure of my discovery that I already thought loved ones were heading to the beach to celebrate with me, I saw fireworks explode in the sky, people in their cars honking on their horns in celebration cheering from all around, I was thinking to myself Eric was going to be just as happy to meet me as I was him....Even turned on the TV to hear the news...but they hadn't quite caught on lol.

The Euphoria you feel on the higher doses I don't think any drug can really compare to it...maybe DMT but that's essentially the same drug( Or tool as I like to think of it)

No, light does not define time in physics.  Time is a fundamental dimension, light is the propagation of EM waves.

The plank time has no physical meaning.  It is just constructed out of quantum constants, its a really small time and we cannot model shorter times.

yay for conflicting views!  thanks for your input as well.


i'm mostly trying to make sense of the claim "if one exceeds the speed of light, they are traveling forward/backward in time" basing time on our own perceptions/measurements.  again, "time-travel" does not seem plausible in any sense, imo, as one is still actively engaged in the moment, not a past moment or a future moment, and that the moment is ever-present in all reaches of the universe as we know it.

Time is a fundamental dimension, but it is defined relative to space, you can't have one without the other. Time will always be defined, eg measured, in relation to the movement of something in space and vice versa. They are intimately entwined and defined by the other.

What do you mean the planck time has no physical meaning? Quantum constants are physical, that's the whole point, that is how you define any unit of measurement. A planck unit is the smallest amount of time that can discreetly exist, or rather the smallest length of time in which a fundamental particle can discreetly occupy. There's no reason to believe reality cannot get smaller, nothing says it can't, but it takes on different properties due to differing physical effects and to talk of discreet particles no longer makes sense. You can argue that our understanding of quantum mechanics is wrong and that the physics that define the planck units are not an accurate description of reality, which may well be true, but it is has a well defined physical meaning just as any other unit of measurement does. If it did not have a physical meaning there would literally be no point in it existing, it wouldn't be science.

Read the wikipedia on planck time.  It clearly states "...there is no reason to believe that exactly one unit of Planck time has any special physical significance."  I don't know why laymen bring it up so often.  I guess that some pop-science show out there has butchered it.


Time travel from relativity is clear if you take some time to do the algebra and look at "space-time" diagrams (minkowski space).  The great thing about relativity without gravity is that you can do almost all of it with simple algebra.  That's not to say that its trivial though.

again, "time-travel" does not seem plausible in any sense, imo, as one is still actively engaged in the moment, not a past moment or a future moment, and that the moment is ever-present in all reaches of the universe as we know it.





Using your reasoning, one cannot travel in distance either.  You are actively engaged at your position, not a forward or backward position.  And the only position you will ever be in is your position.  The idea that space exists forward or backward of your position is part of a model that you invent to rationalize your observations while moving through space.

Time travel, in the broadest sense, is not only possible - its impossible to avoid.  We are all traveling though time to the future.  How fast we get there is relative to our inertial frame.

Read the wikipedia on planck time.  It clearly states "...there is no reason to believe that exactly one unit of Planck time has any special physical significance."  I don't know why laymen bring it up so often.  I guess that some pop-science show out there has butchered it.





It's saying that one unit does not have significance in that there is no discreet point where you can not make measurements/particles can no longer be quantized, it's an approximation of that point. That doesn't mean the unit of measurement has no discreete size, physical definition, or meaning though, that is well defined and fixed (barring new physics that redefine it of course). That's like saying a millimeter has no physical meaning.

A millimeter is the smallest unit of macroscopic measurement on the metric scale and then a micrometer is too small to see, but similarly that doesn't mean that literally anything less than a mm is microscopic and so you could say 'a single mm is not significant,' which is true in that context, but you wouldn't argue that means it has no physical meaning or a fixed definition. Likewise there's no discreet point where quantumn mechanics takes over the effects of gravity on the macroscopic scale or quantum gravity on the extremely small scale, it depends upon the system you're measuring and a lot of problems exist where there is sufficient overlap between them, but the planck scale is approximately where that line begins to blur.

Yeah, that's right.  Light defines time.  If you think about it, everything in time exists based upon the propagation of light.  If you go faster than a light beam, you could create an effect before a cause.




Light. But is light not energy? Electricity?

So what does that mean?

What do you mean what does that mean? In what context? Everything you see is energy, E=MC^2.
