Will We Ever Time Travel? Scientists Say ‘No’ Based on This New Discovery

Will We Ever Time Travel? Scientists Say ‘No’ Based on This New Discovery


So, this is probably what you think of when you
picture an atom, right? The thing is, the central part of this model
is just plain inaccurate. Scientists recently found the nucleus of some
atoms don’t look like this at all, and it’s causing a ruckus because well, this newfound
shape straight up shouldn’t exist. When you learned about atoms in school, you
probably learned about a couple of different models– and one thing was likely always the
same- the nucleus was spherical. But it turns out that might’ve been too
simple. Atomic nuclei are made up of protons and neutrons
that are held together by the Strong Nuclear Force (one of the universe’s fundamental
forces), and based on this, one might assume they’d be more or less spherical. In reality, though, most nuclei are deformed
to some extent, they can be elongated into football shapes or squished into discs– but
as long as they’re symmetrical everything in physics land is fine and dandy. Here’s the problem though, we just found
a nucleus that ISN’T symmetrical, and it’s a huge deal. And that’s because symmetry is a very important
cornerstone to many of the theories we use to understand the universe. In particle physics, there’s a theory called
CP-Symmetry, which is the combination of charge symmetry and parity. Charge symmetry is the idea that if you flip
the charge of an atom, the physics of the atom shouldn’t change. This is the basis to our understanding of
antimatter- if you flip the charge in a regular atom, you get an anti-atom. The physics should work the same. Similarly, Parity is the idea that if you
invert the spatial coordinates of a system, the physics shouldn’t change. Our hands, for example, show parity- if you
move one hand like this, you can mirror it with your other hand- and it works the same
way. Theoretically, atoms should behave this way,
too. So, back to the new hotness. Some Scotland-based scientists confirmed a
pear-shaped nucleus exists. A PEAR, YOU GUYS! The most exciting shape of all the fruits!!! Scientists had previously found asymmetrical
nuclei in the isotopes Radium-224 and 226, But this time they confirmed it in Barium-144,
which is a comparatively lighter atom. And how’d they do it you ask? They just looked for octupole transitions
in the gamma ray emissions of excited ba-144 nuclei, casual. And the surprisingly pear-shaped nuclei they
found had uneven distributions of mass, and charge. Which according to currently accepted models
of physics, like CP-symmetry, just shouldn’t exist. But THEY DO. And the scientists think that could have some
very big implications. Our current models predict the symmetry of
antimatter and matter, and of the flow of time, but the scientists think that these
nuclei being asymmetrical could explain why these other things don’t function symmetrically
either. If some atomic nuclei aren’t symmetrical…
they’re claiming it could explain why we can’t seem to find antimatter in our universe,
and why time always flows from past to future — and therefore, why time travel is likely
impossible 🙁 These are some pretty hefty claims, though,
and as always more research is needed before we can prove anything. But it is pretty amazing that such a tiny
discovery could have such huge implications, innit? Special thanks to Domain dot com for sponsoring

  1. We might be able to travel into the future but never into the past. If we could travel into the past we would living in a utopia. Nothing bad could or would happen. We would all live forever and without sickness. "Time" would have been perfect throughout human history. Well, perfect to our current understanding. We could go anywhere and do anything. Nothing would be beyond us. None of that is happening so no, we cant travel into the past. Before you ask "Well, time travelers cant change things or they will change their own future." Wrong, time is immutable. What has happened will happen. So I guy traveling back in time killing his own mother would have never been able to travel into the past at all or the guy would double his age in a instant or time simply would not allow it. So, I would take my magic level technology into the past and make all human lives better and we would have utopia from that point on.

  2. Well, sort of an explanation… I have read that time travel is possible BUT only between already built "ports". Therefore all time travel is in the future and the past is protected. Yes, it sounds self-serving but there it is.

  3. so i thought that doing some black hole near-event horizon surfing, without being destroyed would create away for us to use time dilation to only go forward, but not backward. hopefully we still got that going for us.

  4. Time travel is plain impossible, how can u rewind back to an event that has happened? The universe isint a video on a computer, anything we don’t don’t get saved in some sort of memory drive.

  5. Scientists also said Pluto wasn't good enough to be a planet and revoked its licence. Now they bit their tongues: Pluto's back b*tches!

  6. Your explanation of why they can’t be time travel makes no sense. You’re intelligent, do you know what a DVR is, and I’m sure you have used a DVR. If it’s been recorded from the past you can watch it. You can rewind itAnd you can do this watching near live TV. Just because you can’t explain it doesn’t mean it doesn’t exist. You see it every single day if you have a DVR.

  7. It doesn’t matter what the shape of atoms are. We need to access higher dimensions to time travel, and we cannot access these dimensions alone.

  8. Time is likely cyclical not linear though. We don't know how to observe the past from this perspective and in 3D. Time might reside on a higher plane and we can only see its cycles or the line they form attaching semantics to our observations.

  9. yeah,if we would ever make a rocket as fast as light,we wouldn't time travel to the past,everything becomes pause instead : ( .

  10. Some secret goverments already has the technology to time travel as they been contacting extra terrestrials and reverse engeneering their craft for years now.

  11. I wonder what would happen if you got the top 10 smartest minds in a room in the present world.. And make them all smoke 10g of weed..

  12. the nucleus of all atoms doesnt look like that, and also the electron field around them isnt shaped like that either. that 1950s ass model has been known to be inaccurate since like forever

  13. Some nucleae have pear form so time travell is imposible.Ok thank you, I will use this argument with my wife. "im sorry I couldnt bring milk from supermarket because… some nucleae are pearformed"

  14. "time travel" Indy literal sense probably not possible… But if you have the technology to control every particle in the universe you could theoretically turn back the clock by simply arranging them in the order they were in in a different moment in Time. Obviously this would require technology of a "god" and by no means am I saying we can do it but I think it's the only way to "go back in time"

  15. As for traveling to the Future… I do that every weekend when I start drinking… Wake up Sunday morning like holy s*** I time traveled because I can't remember anything from Friday or Saturday LOL

  16. But honestly time travel to the Future can be done a few different ways you can slow down time relative to you, you can go to the past rearranging all the particles like I mentioned before then alter something pull yourself out of the equation via slowing down time relative to you then re-enter after a period Of time and see how your change affected how the particles in naturally reacted in the time u we're gone. Again I'm not saying any of this stuff is possible with our technology but theoretically it can be done relative to us… Obviously there has been studies proving that some particles only flow one direction and that's forward through time I cant remember the woman's name but she proved that. she was some Asian lady I think got a Nobel prize in science…

  17. In conclusion time travel Andy traditional sense not going to happen but someone could theoretically rearrange our reality and it would feel like time travel to us…. Oh crap what about my consciousness though!!! More information is needed LOL

  18. time is relative….my body got 4 minutes older setting here…but my mind was outside of this dimension listening to this video so i didn't notice my body getting older until i came back…….stupid people

  19. It is simple to prove that time travel does not exist, no need for any background in theoretical physics.

    If time travel was possible than someone from the future (like in movie terminator) would already have travelled back in time to our present and told us about it.

  20. If time travel ever were to exist we would have already known about it because people would have travelled back in time to our age.

  21. Time is simply states of change you would have to undo all states of change throughout the universe which is only possible in a simulated state, say a computer program.

  22. And let's just say you could travel through time… how would you be sure you would end up on earth and not in a space somewhere floating in the dark.? Because the last time I checked were on a rock falling around the sun and the sun is moving through the galaxy and the galaxy itself is moving through space?

  23. A specific future doesn't exist.. What we do now @ present becomes the Future and the past for us when we r in that future!

  24. It would be cool if we could time travel we can shoot Adam and Eve and solve all the Earth's problems Humanity destroyers of planets in life

  25. Time travels from past to future because of the Big Bang when everything stops So Will Time.
    I'm a Genius hahaha

  26. Difficult, yes . Impossible, no. Like most or some discoveries or inventions we discover them accidentally . A way to travel through time was possible, ( forgot year, have to consult/ refer to source ) we lacked the equation or method to control the where and when. USA may have solved that by now , don't know . USA Government doesnt want to trust us with that knowledge like many other information . But, my source could be wrong . ? ?????

  27. It is believed that the weak nuclear force does not act upon antimatter the way that it does on matter

  28. I predict that one day time travel will be possible so I can go back in time to when I was a kid because I miss being a kid

  29. Then how can we go back in time and we can use our smartphones to take 4k UHD and in color pictures of our own town hundreds of years ago. Especially back in the mid to late 1800's! They did say time travel may be possible by 2025! You wont physically go in time, it'll be more quantum jumping or something like that.

  30. Can we go sideways in time?
    That sounds fun,
    Let's get the scientists together with a lock in at the rec center, order some pizza and Sprite, and do a study or mind meld or something.

  31. In 1970 scientist all agreed Earth was plunging into the next ice age, it was presented as a fact anyone who did agree was nuts! So maybe 50 years from now time traveling will be touted by science as a fact not to be argued with

  32. It’s not possible to travel in something that doesn’t exist; Time is a concept that we invented a long time ago to help us make sense of our Existence. We are Immortal Beings currently experiencing a mortal existence. That’s why it’s always Now. That’s why everything happens Now. The Now IS Eternity, plain & simple, y’all. You’re welcome ?.

  33. I never believed in time travel. Time doesn’t exist. Time is just a progression of events. We can define time through measuring change, but time itself isn’t observable.
    And I am not saying I understand everything, but it never made sense to me, and my intuition is usually right.
    Like nuclei oscillate at different rates depending where they are in a gravitational well, or their velocity.
    In the way that metabolism is slower in colder environments.
    Environment changes the forces at work and thus the way we measure what we call time changes
    Time itself does not change, because it doesn’t exist and is just what we measure as a combination of other things
    This is how I think of it

  34. Time travel into the future is possible, but you would need to go faster then the speed of light, but going back in time is impossible!

  35. Science is not equipped to prove something doesn't exist. It can only confirm the existence of something that is observable. If it hasn't been discovered yet it can't be observed. Science cannot prove or disprove future discoveries.

  36. Everyone knows all ya gotta do is stop the earth's roation and make it go backwards just like Superman. Only problem is, Superman is just an imaginary character.
