Searches for Superluminality, Aliens, and Impossible Knowledge with Dr. Robert Nemiroff

Can anything go faster than the speed of light?
Scientific Searches for Aliens, Superluminality, and Impossible Knowledge are all subjects that John Michael Godier discusses with Dr. Robert Nemiroff a professor of physics at Michigan Tech. Dr. Nemiroff is hosting the 100th anniversary of the great debate between Harlow Sapley and Herber Curtis with a new question, how will humanity first discover extraterrestrial life? Other discussion subjects include, Is time travel to the past possible? One way to answer that is by searching the internet for evidence of time travelers.

Fun Fact, in 1997 a screenplay was anonymously submitted to Warner Brothers Studios, it was a Disaster movie called 2020: The Year the Shit hit the Fan, it involved a global pandemic originating out of China, a horribly botched response to the pandemic which began a domino effect of society falling apart mainly through corruption and sheer incompetence at every level of government, had people attacking each other over toilet paper, stores and banks demanding customers wear face masks to be allowed to enter, the entire economy was just "stopped" and the President of the United States was a Reality TV star with dementia who was telling people to inject themselves with bleach to avoid getting sick as riots and protests broke out in every major city while everyone else was stuck in their homes with glass rectangles glued to their faces giving them regular dopamine hits. While it remains the most solid evidence of a time traveler trying to warn us of what was coming, no one ever heard of it because it was considered too ridiculous, overcomplicated, and nonsensical. And besides, Y2K was gonna be the end of the world anyways.

Have you seen "Soylent Green" 1973, it had people wearing masks, shortage of food, a totalitarian government but with one main difference: as people died they were recycled into food. So only one or two steps away from where we are now.

With regard to FTL time travel- the solar system itself is moving, and without knowing the numbers, I would presume the Galaxy is moving at near-relativistic speeds itself, or at least very fast, so it doesn't seem like the idea of coming back to the same place really means anything at all. When you come back to the same place, the place is in a different place.

Time travel may be possible but only as an observer - like a movie rewind and fast forward but you cannot interact , events in the past are set and the consequences of today determines tomorrow.

[@tasosparisinos6893]

A thing not mentioned, when it comes to FTL, is that it starts to look like, the Hubble Constant, is not a constant at all. What that means, about different areas of the universe, different times, and probably different Light Speeds

[@timm4811]

Not a Joke. I personally believe that the universe is not expanding. The most simple answer would be that the speed of light is slowing down. Yes, the 'yardstick' that Everything else is measured by.

[@channelwarhorse3367]

Per generation content of time and space, faster then light can not curve beyond content relative. Per energy Event Horizon entanglement beyond light is still relative, per frame, energy is relative. Rs, is FTL.

[@channelwarhorse3367]

@@timm4811 as g subs to zero, entanglement happens per frame. Blackhole is immovable. We are movable. Expand to understand faster then light travel, Rs is the projection per system Applied Frame.

[@tasosparisinos6893]

@@timm4811 Well this is more than hard science, I mean the electromagnetism theory. It is pretty pretty sure that that's the speed of light. Also everywhere and no matter how we move around, from everywhere the light is measured to have the same speed, no matter, the frequency. The frequency is red shifted, when we talk about galaxies, out of the Laniakea Supercluster (our own cluster, not galaxy). The far they are, the more the red shift in frequency (towards IR). So it is hard to doubt that, it will take a lot of work and it is not gonna be handy, either. I mean relativity is so nice because you don't have to use, all those complex space references, instead only one thing is constant, SOL and space and time are relative. The problem is not if it expands, but, how it expands, is it uniform? It starts to seem doubtful. That, you can doubt, with current data

[@timm4811]

@@tasosparisinos6893 So called 'Red Shift' is simply weaker, less energetic light, not necessarily farther away. A professor from Tel Aviv, at Cal Poly, froze light momentarily, slowed the light beam down enough to embed information,when released the light came back up to speed carrying the information to target. Also "most' red-shift has been found to be digital, rather than a smooth transitional event, indicating something other than distance alone to be involved.

[@bozo5632]

From the perspective of the passengers aboard a ship moving at 90% of c, they might as well be traveling faster than light. It won't look like it if they look out the porthole, but their clocks will show they traveled farther in less time than light speed would make possible. So we can sort of travel to other stars "faster than light," but we would go out of synch with the folks back home. (Which would happen anyway due to light years of internet lag.)

From what I understand the speed of light has nothing to do with light. It is the speed of causality.

[@erikjarandson5458]

What's more anthropocentric? What makes us feel smaller and more alienated? Believing that we're alone in the Universe, or believing that the Universe is inclined towards things like us (life)? What's more like believing we're the center of the Universe? What makes the Universe "larger" and more intimidating? Which concept is more alien to our minds? I'm not at all sure that "the Universe is teeming with life" is the braver, less emotional, more rational and more open-minded belief. In fact, I'm pretty sure that the belief we have the greater emotional resistance to is that we're alone. That's certainly the case for me.

[@digitalfootballer9032]

If it were possible for a human to create a vessel to travel at the speed of light, theoretically, the occupant could go anywhere in the universe instantaneously (from their own perspective) as time would slow to a stop, correct?

[@alanheadrick7997]

Something I wondered about is a ship traveling at maybe 10 to 20% the speed of light. Now space is not a total vacuum, there's dust and some gases, denser around nebula's. So I'm thinking as a ship traveling through this would create some sort of glow. Maybe around the nose, but maybe it could look like a glowing comet. Not sure. Maybe it would be bright enough to see with modern telescopes. Just a random thought.

It would need some sort of navigational shielding field to deal with all the micro collisions or the ship would ablate to nothing in the star dust.

47:49 we could have a situation where we discover life (on Mars for example) and there is a debate for awhile over whether it's truly alien (or contamination) because of how close it is in relationship. You have 3-4 billion years of microbe evolution on Earth, during which panspermia between the planets could have been active. What if we discover Martian microbes and it shares a root DNA, or what if it's even older than our microbial life (frozen in time so to speak)? Perhaps the question we should be asking isn't whether or where we discover "alien" life, but how different will it be in relationship and how will we then be able to draw a genetic tree for our Solar System?

[@TheAsmodeus2012]

The first rule of time travel, is: 'NEVER tell anyone you're a time traveler, or otherwise allow it to be found out.' Stephen Hawking once advertised and threw a party for time travelers, to see if anyone would show up to prove, or disprove the possibility of time travel. But he never could have checked with everyone who passed by on the street at the appointed hour, or who may have sat in nearby pubs, possibly drinking a quiet toast to a man they dare not meet and for a party they could not attend...

[@lohphat]

Time travel can easily be falsified by the conservation of energy. Leg. If we could send an apple into the past located nearby the apple as it existed at that time, we then have ask the question of where the atoms came from to allow the two apples to coexist in the same time frame. It would require that protons, neutrons, and electrons would have been spontaneously created out of nothing to appear suddenly next to the preexisting version of the same particles. In essence, you have to replicated existing particles somehow from the perspective of an observer of the now two apples.

[@Laotzu.Goldbug]

To be fair, this is really only true it given to a strict classical Newtonian interpretation of mass and energy. Considering everything we don't know about basic matter, never mind seems like dark matter and dark energy, it would be perfectly possible that some kind of Time Machine would drawn or influence that more subtle layer of the cosmos, and effectively shift around that matter and energy as needed, depending on where something pops into existence, without violating the fundamental conservation of energy for the complete universe as a whole over it's entire lifetime.

[@afriedrich1452]

Will a gravitationally charged particle moving through a gravitationally charged medium also emit Cherenkov radiation? Will a weakly charged particle moving through a weakly charged medium also emit Cherenkov radiation?

[@HotPinkst17]

No, Cherenkov radiation is formed only be beta particles (high speed electrons) traveling through water faster than photons travel through water. The beta particles form a shockwave of photons as they collide into the back of them pushing their way forward. The photons are pushed forward and aside with some of the energy of the beta particles and are boosted to higher energy by the collisions, hence the lovely blue glow. Not sure what you meant by gravitationally charged objects.

The discussion about knowledge known before it should be made me think of the claim that some tribe was aware of a brown dwarf in the Sirus star system before any telescope existed that could see it.

I think trying to change things would be very problematic, but the curiosity of what would happen would eventually probe someone to do it anyway. I wonder what would happen if the industrial revolution occurred 4000 years prior to it's actual occurrence. Or if the airplane had been discovered in 100AD

[@HotPinkst17]

We probably would have created a global catastrophe and barely survived, forgetting everything and started over. With history barely having evidence 10,000 years ago and our species being modern humans for at least 100,000 years we've had time to rise and fall plenty of times and never know it.

[@frost1947]

The furthest reaches of our universe appear to be racing away from us at speeds up to and at the speed of light, does this appear the same in viewing from the outward locality looking back. I seem to see a relevance in speed unique to the viewer if this applies, no? At the furthest reaches outward of our universe due to expansion, as I've read many times, galaxies are moving outward at the speed of light or close to this, given a person in this location, who would not be moving seen from their perspective but see perhaps us moving away from their location, the concept of motion becomes very relevant, does the speed of light restriction appear in place from both locals?The idea "someone from the future" is taken seriously seems ludicrous, if we are the present than the future has not happened and as such does not exist yet so no one can "come from the future" without it being a convoluted science-fiction story or we are not in the present and if we are not in the present we have no prescience.

[@jmleaf8102]

The Milky Way Galaxy moves through space around 2.1 million kilometers per hour. This came from a scientific paper that appeared first when I googled up the speed of the Milky Way Galaxy through space. I think what you are stating is not just the visible universe. The universe beyond our vision is only one theory among many concerning the speed of light and the movement of mass through Einstein's spacetime. I am starting to find that when people talk about a "time machine", they are only talking about time. If you want to go back in time to a particular time and place? Let's say that you want to go back in time so that you can go in your front door the day before. Your machine takes you back in time to the day before. How does your machine go back fifty billion kilometers to that point in space where your front door and the planet Earth were twenty four hours before? Finding the answer to that conundrum might help.

@6:50 - The line that you refer to doesn't move faster than light. Light occupies a space which gives the appearance of there being a line that moves. Essentially the shadow is removed by the presence of light. That doesn't mean shadows move faster than light. Or am I missing something here?

[@pwuk]

Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it. -- Terry Pratchett

The part about astrophotography being easier with modern equipment made me wonder about something. Are ghost and spirit photos as common now as they were in the 90s? On one documentary I saw, they said that cheap cameras captured them most often. (I figured out the reason pretty quickly.)

[@nkordich]

I think it's safe to say it certainly hasn't increased at the same rate at which cameras have become ubiquitous - both security cameras and cell phones. Not only have camera image quality improved, both in respect to low light photos and avoiding flim-specific aberrations, but it's become far easier to share photos and video. It's also easier to fake a photo or catch a digitally-altered photo if someone claims it shows a ghost, leading to more skepticism and a risk of someone providing an alternate explanation.

2:00 you can’t “flick a laser across the moon” faster than light. All you can do is produce a stream of coherent photons traveling at light speed in an arc, like a garden hose. It would produce a scattering sequence of particles that spreads out and leaves gaps on the target like a machine gun. I think Vsauce or Veritasium covered this

The practical factors enforcing c for massive objects relate back to those enforcing the conservation of momentum, and in turn, the conservation of energy. Taken as F=mA, Newton's 2nd implies the necessity that forces may only meaningfully be applied between inertias - that there can be no application of work by unilateral forces as from thin air - and thus in turn seguing into N3; reciprocity of the resulting counter-momentum.. whatever the ratio of interacting inertias, the change in inertia times velocity product in each direction is equal and opposite at all instants, hence the net system momentum always remains pegged at 'zero'. This 'zero momentum frame' likewise thus sets the shared inertial reference frame for any resulting PE or KE metrics; in the former case we typically multiply force and displacement, and for the latter we take the inertia times the velocity squared: in either case, distance and velocity - being intrinsically relative concepts - are relative _to_ whatever body constitutes the counter-inertia that is being accelerated _against,_ and this sets the symmetry of PE to KE plus losses, or input vs output energies. To put it another way, the conservation of energy is not a fundamental law unto itself, but rather an epiphenomenon of the more fundamental time conservation of momentum. Ask yourself however why it is that KE squares with velocity.. why, at double the speed, do we have four times the KE, rather than just twice as much, per the case for momentum? The answer turns out to be N3 again; the distance over which a given force must be applied in order to maintain acceleration is squaring with the rising velocity between the two interacting inertias, ie. between the body manifesting the desired momentum gain vs whatever's embodying the reaction matter and counter momentum. Thus, the squaring nature of energy with velocity is seen to be intrinsic to the means of raising it this way, in accordance with the seemingly-inescapable practicalities of Newton's laws. Except of course we're not really 'raising momentum' as we've already noted - the change in net system momentum when accelerating this way remains nil at all times. We don't 'buy' momentum with energy, but merely rent it, and the more we hire the greater the unit rate.. the economy of scale in this case favouring lower values of relative velocity, where the unit energy cost of momentum remains at its lower bounds.. For a 1 m/s acceleration of 1 kg, that works out at half a Joule (KE=½mV²). What if we could somehow accumulate momentum at that fixed unit energy rate? Net cost of accelerating 1 kg to c would be ½c J - that is, half lightspeed in m/s, expressed as Joules.. ie. a finite amount. To fix the unit energy cost of momentum this way, we must forego the factors causing it to square with relative velocity. That is, we must source and sink momentum directly to fundamental force constants and time; ie. ambient quantum momentum via time-asymmetric gauge boson interactions, gaining or losing momentum equal to the per-cycle I/O time delta multiplied by whatever the given force constant, these reducing to +/- dp/dt constants. This accumulates absolute momentum at a constant, speed-invariant efficiency, generating a divergent inertial frame and breaking CoE with all other FoR's.. Note that this exploit still _depends upon_ the time-conservation of momentum, albeit now held over a barrel..

[@digitalfootballer9032]

So if matter cannot reach the speed of light, do we have a theoretical speed limit for matter? Like 99% c, 90% c, etc, or is it unknown at this point?

[@u.v.s.5583]

There is no such limit, at least for massive elementary particles.

[@cf453]

It's a question of how much energy you can apply to that matter. It takes an infinite amount to accelerate it to the speed of light. en.wikipedia.org/wiki/Limit_(mathematics)

[@1966human]

What about observation isn't that faster than the speed of light, or is the light traveling toward the observer

[@channelwarhorse3367]

Curveing time and space per center, which controls the projection of energy content, the Observer would only see if the operator of gravity induction engine wants you to see. Rs, dangerous.

[@euclidofalexandria3786]

time valued effects, ordering chaos is one type of this signature.

[@LemonLadyRecords]

Great episode and guest, John (trying to sound like Anna). I love how well he communicates complex concepts. I bet he's a wonderful prof.

[@genorzt]

if you see the light its faster then light :> yeah nice episode

[@driverben]

Every second/day we all are traveling into the future...

[@philaypeephilippotter6532]

Well, most of us anyway.

[@laurachapple6795]

In keeping with topics discussed in this interview... if I could go back in time I would go to September of 1999 and reassure all the disappointed MSTies that if they wait long enough they'll get twenty more episodes.

[@bjorntorlarsson]

If I time traveled back in time, I'd (tempus non-descript) tell everyone about it. I'd win the Nobel prize, because I'd read the paper of the other guy who actually deserved it. I still wouldn't have bought today's stock market. I wouldn't have believed it.

[@BRUXXUS]

Over an hour! You spoil us!

[@CaptainHarris-ip2kg]

I think masses can move faster than light with a better understanding of heat and time. No mass can naturally travel faster than light, but C is the limit at which things or radiation can naturally propagate, and given that dilation is a difference in exposure to ambient heat, part if the issue is to both shield and utilize that heat to mitigate time dilation and propel your mass to C and beyond. The engineering requires a better understanding of field dynamics, and I believe the experts are on the verge of such breakthrough.

[@jackparker8686]

Who can decide what makes a good envoy

[@jackparker8686]

We like to safely dream things out of our reach... Fantasize about time travel and possibilities and shoehorn them into axiomatic status

[@jackparker8686]

Things needs to move exponentially here... I give only food for thought dare I be that big even...

[@MCsCreations]

You know what... It would be amazing if we find independent extraterrestrial life and it also had DNA.

[@thisiszaphod]

Travel to Knowle West - there's a good chance of finding something there.

[@u.v.s.5583]

Imagine getting a SETI signal that goes like: This is who we are, this is what we do, greatness is in our DNA!!!! (in the voice of E. Thomas)

[@HotPinkst17]

Would be real lucky for the first aliens to use DNA as well, but am certain their are many many aliens in our galaxy that independently evolved DNA. Abiotic chemistry creates the conditions for self forming membranes in the presence of nucleotides and amino acids. Since these are ubiquitous ingredients it stands to reason it happens everywhere it can. So few species evolve civilization here on Earth, like one we think (if you call this civilized) out of millions... so we are dealing with the rareness of advanced enough civilization to reach us and to happen to strike out in our direction. DNA and life can be everywhere and still not have much of a chance of finding us. Perhaps when you are advanced enough to reach other planets, cells are obsolete and bodies have been replaced by digital living or nanotech bodies.
