Does antimatter go back in time?
In terms of the known laws of physics, antimatter behaves mathematically equivalent to normal matter simply traveling backwards in time. Effectively antimatter particles are indistinguishable from normal matter traveling backwards in time on a particle by particle basis.
Do positrons travel 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.
Do particles travel back in time?
Physics. Aspects of modern physics, such as the hypothetical tachyon particle and certain time-independent aspects of quantum mechanics, may allow particles or information to travel backward in time. Logical objections to macroscopic time travel may not necessarily prevent retrocausality at other scales of interaction.
Do electrons travel in time?
The time frames, in which electrons travel within atoms, are unfathomably short. For example, electrons excited by light change their quantum-mechanical location within mere attoseconds – an attosecond corresponds to a billionth of a billionth of a second.
What would an antimatter universe look like?
In that case, an antimatter universe would never form stars or galaxies. Our antimatter universe would simply be filled with traces of anti-hydrogen and anti-helium, and nothing would ever look up at the cosmic sky. While we think antimatter has regular mass, we haven’t created enough of it in the lab to test the idea.
What if time moved backwards?
That means that it doesn’t matter whether time moves forward or backwards. If time ran in reverse, all the laws of physics would work the same. The Second Law states that over time, everything moves from an ordered state to a disordered state. It’s the only physical law that can’t go backwards.
Can electrons be in 2 places at once?
About 80 years ago, scientists discovered that it is possible to be in two locations at the same time — at least for an atom or a subatomic particle, such as an electron. For such tiny objects, the world is governed by a madhouse set of physical laws known as quantum mechanics.
