Has Anti matter been observed?

No macroscopic amount of antimatter has ever been assembled due to the extreme cost and difficulty of production and handling. Theoretically, a particle and its antiparticle (for example, a proton and an antiproton) have the same mass, but opposite electric charge, and other differences in quantum numbers.

Can particles move backwards in time?

Hypothetical superluminal particles called tachyons have a spacelike trajectory, and thus can appear to move backward in time, according to an observer in a conventional reference frame.

Is positron Travelling backwards in time?

An electron travelling backwards in time is what we call a positron. In the diagram, the electron travelling backwards in time interacts with some other light energy and starts travelling forwards in time again. Note that throughout, there is only one electron.

Why does antimatter travel backwards in time?

They move through time just like any other particle. Anti-particles are just like regular particles except they have an opposite charge with the same magnitude. They’re said to travel backwards in time because they are mirror images of their opposite particle partner.

Is antimatter found on Earth?

The Big Bang should have created equal amounts of matter and antimatter in the early universe. But today, everything we see from the smallest life forms on Earth to the largest stellar objects is made almost entirely of matter. Comparatively, there is not much antimatter to be found.

How does antimatter annihilate matter?

Antimatter particles share the same mass as their matter counterparts, but qualities such as electric charge are opposite. Matter and antimatter particles are always produced as a pair and, if they come in contact, annihilate one another, leaving behind pure energy.

Does the future determine the past?

THE future can affect the past, according to a bizarre new theory which adds even more weirdness to the strange world of quantum mechanics. With distance between the particles not being a factor, researchers have now set out to discover whether time plays a part in quantum mechanics.

Do physicists believe that antimatter is matter moving backwards in time?

To the best of my knowledge, most physicists don’t believe that antimatter is actually matter moving backwards in time. It’s not even entirely clear what would it really mean to move backwards in time, from the popular viewpoint. If I’m remembering correctly, this idea all comes from a story that probably originated with Richard Feynman.

What is the difference between Feynman and Wheeler?

Wheeler, to the contrary, was full of wild ideas, from there only being one electron in the Universe to viewing antimatter as normal matter traveling backwards in time to the idea that there were no particles, only information. Richard Feynman and his family with their custom-painted van in Altadena, California. While Wheeler [+]

Who was Richard Feynman’s advisor?

Meeting at Princeton in the late 1930s, graduate student Richard Feynman and his young advisor, John Wheeler, would begin a working relationship that would bring forth some of the greatest ideas in modern physics, along with a friendship that would last a lifetime.

What happened to Richard Feynman and Richard Wheeler?

Feynman died relatively young after a decade-long battle with cancer; Wheeler lived almost to 100. But both remained active in physics and problem-solving until the very end of their lives. In fact, Feynman commented that although Wheeler appears as a crazy old man now, you must realize that he’s always been crazy.
