Ronald Lawrence "Ron" Mallett is an American theoretical physicist, academic, and author. He has taught physics at the University of Connecticut since 1975. He is best known for his scientific position on the possibility of time travel.

Doesn't he mean meet his dead father?
I can't pretend to know as much as this man, nor can anyone on this site, but from what I do know, time travel can't go backwards, but forwards
Kek
He stated that when finally build a time machine we would only be able to travel back to the point when the time machine was first built.
sounds like an absolute fucking quack, people published criticism and he didn't bother to answer
Really? Where's the proof?
oh god primer is real
Seems like it is senpai.
criticism + theorem that say it's not possible

the past doesnt exist
Time doesn't exist. You can't go, "back in time." Hell, you actually can't go "forward in time" either. There is literally only the present. This is why relativity exists. It is the red flag that shows you time isn't real.
our reports showed a massive anomaly in the timespace continuum. timelines jumping left and right, starting and stopping... until suddenly, everything ends.
>Time doesn't exist.
Consider the implications of relativity across the entire universe. Even the fact that light does not experience time, because time stops from the perspective of anything traveling at the speed of light. Light that has been moving since the beginning of the universe has not experience ANY passage of time--it's still the first moment of existence for those photons, and always will be.
First, copy an atom;

Two entangled particles can be considered one particle. A superposition is, therefore, a single particle smeared across space.
Let's take this superposition, and suppose that the two particles are 299,792,458m away from one another. Between these particles is 299,792,457m of medium with a c of 299,792,457m/s, and 1m of 0.1m/s medium. So, it takes light 1s to travel all but 1m of that distance, and for that final meter it takes 10s.
Two entangled particles respond instantly - vector and velocity, which are quantum states, can be communicated in this manner. If you pull one particle 1mm to the left, the other particle complies.
For this to happen, a negative group velocity has to be attained. In other words, it's not enough for QE to be instant - the signal has be received before you send it.
Unless, there's something to this concept of superpositions as smears. That is, if the smear was a real physical entity - if the entire smear's outside surface was the doorway to an inner room conpacted by, say, a blackhole - than it would take less time for information to travel through the smear. In fact, this is cutting edge theory - pic related.
But if it arrived before it was sent, this could cause the sender to never send the message in the first place - the grandfather paradox. To shrug it off, we have to suppose that neither the arrival of the message nor it's departure have absolute dates - they have an absolute quantity of time between them, but the events themselves exist timelessly.
But if the events exist timelessly are can't be prevented or changed, then we live in a deterministic universe - a superdeterministic universe, if you will.
Locality would be defined by degree of entanglement - that is, the more similar two cubic volumes of space are, the more they seem to physically overlap. A moment is created by viewing a static, 3D hologram from a moving perspective.
Well that would explain the "where are the time travelers" problem.
I take classes in the same building he researches in.
Red-shift and blue-shift thus represent the past and future, reapectively - things moving away from you are red, things going away from you are blue. The older stars are found toward the edge of the galaxy - the younger stars toward the center.
An object can be said to exist as a superpositioned smear, blue in the center and red at the edges. To see something as it was, go to the center. To see it how it will be, go to the edge.
There's evidence to support the notion of blackholes continuously absorbing and emitting the same matter;
>adsabs.harvard.edu
So, the past is to be found close to the supermassive blackhole at the center of the galaxy, and the future is to be found at the galaxy's edge. The blackhole defines time in terms of distance.
And if you were entering a blackhole, everything around you would seem to be receeding - except for the blackhole, which would appear to be approaching you. This is exactly how the universe looks - the galaxy isn't moving away from us, but the rest of the universe is.
Hugh Everett knew the central kernal of this, and believed in quantum immortality because of it. I've felt this timelessness, and seen the universe as motionless.
Is this even accurate? Where is the bazianic theory? I don't see a sequential eske atomic profile anywhere. GTFO!!
What are you even talking about?
No it doesn't. Think of how fast technology has grown in the last 100 years. Now imagine a time traveler from 2100 comes back, bringing his knowledge. Our tech would increase substantially. And so the next time traveler from 2100 will have even better tech; unless there is absolutely no way to travel back any further, eventually we'll have a time machine that can travel back to before it was invented.

Article says "reconnect" as in they've met before
The physicist is black so user was pointing out the fact that he didn't have a father growing up
I'm dumb as shit and I got that joke
only if it's moving through a vacuum
all /pol/ aside i think he is just experiencing grief
a ton of people have tried to reconnect to dead loved ones, just because he is a scientist doesn't change its impossibility
>Works at UConn
>Black
lel no
If you fuck around enough with space it's entirely possible, but the implications would be disastrous. Causality would prevent him from meeting his father.
Is this shit correct
>A moment is created by viewing a static, 3D hologram from a moving perspective.
pic related in 3d?
he's not trying to actually meet his father
the machine he designed can only go back to the point in time at which it was switched on
he just talks about his dead father being the reason for his interest and the press like a nice story
Dumbest thing I've read on Veeky Forums today. gg user.
cool n shit but what about the paradoxes?
nice logic user, are you 11?
Yes, exactly.
That makes a lot of sense. If we find a massless particle that can travel faster than light, we can send it back in time as information, a morse code of sorts. Of course that information will be useless unless we don't make a machine that can detect and translate it. In theory it could work.
> faster than light
it became another timeline the moment you traveled back. whatever you do won't change your history in the original timeline
Imo find mai daddy bai buildin a taime masheen.
Yeah, that's why time travel isn't possible yet. Go figure.
WE
Ayo hol up
Hol up
Some cracker says he's gonna put 100 guys on Mars in 10 years and we believe him but when a black guy says he can build a time machine everybody laughs. Racism.
It looks like any motion is time travel according to the common idea of time travel. Distance across t? How could one be a Physicist and not logically reject an argument like a time machine.
