This Cosmic Timekeeping Methodology Proposes to Synchronize All Clocks on Earth


Trendy expertise pulses with a heartbeat measured in microseconds. From international positioning techniques to communications networks, it is vital each element falls into near-perfect synch.


Primarily based on requirements decided by a specialised job group, alerts despatched via optic fiber or down from an orbiting satellite tv for pc have a tendency to make sure time-sensitive expertise matches moments right down to the nanosecond.

But this is not at all times going to be the case. Reliant on fallible electronics, separated by huge distances, hidden beneath waves and stone, it is easy for very important items of a community to lose the beat.

Based on College of Tokyo geophysicist Hiroyuki Tanaka, it could be excessive time we regarded elsewhere for a extra dependable, extra accessible timekeeper. Wish to the sky, and above.

“It is comparatively simple to maintain time precisely lately. For instance, atomic clocks have been doing this for many years now,” says Tanaka.

“Nevertheless, these are massive and costly gadgets which can be very simple to disrupt. That is one motive I’ve been engaged on an improved solution to hold time.”

Referred to as cosmic time synchronization (CTS), Tanaka proposes we use the subatomic fireworks that bathe down from collisions between excessive vitality cosmic rays and our environment.

These collisions generate quite a lot of particles, considered one of which is the heavyweight cousin of the electron – the muon.


These beefy bits of matter shoot in the direction of the planet’s floor at near the pace of sunshine, respecting little in its path. Maintain out your hand and you may anticipate a muon to punch via your palm as soon as a second.

Even the rock beneath your toes struggles to dam its path, a characteristic that makes them good for shining a light-weight on the insides of dense constructions just like the Nice Pyramid of Giza.

Crucially, each bathe of muons rains down in a barely distinctive style, offering a signature explosion that may be detected independently by sensors unfold throughout a number of sq. kilometers.

By sharing particulars of every occasion and dealing backward, a community can use a sequence of cosmic muon fireworks to synchronize their watches with split-second precision.

“The precept is powerful, and the expertise, detectors, and timing electronics exist already. So we might implement this concept comparatively rapidly,” mentioned Tanaka.

It is easy to think about an online of muon-catchers on the ocean flooring or scattered in distant areas, rigorously synchronized to align observations that would assist pinpoint earthquakes or warn towards tsunamis.


Based on Tanaka, the expertise might even have an added benefit of serving as the premise for a brand new sort of international positioning system by mapping muons again to their supply.

Whether or not such expertise might increase present strategies, serve as a substitute in choose conditions, or exchange it altogether, is but to be seen.

“Thomas Edison lit up Manhattan beginning with a single gentle bulb,” says Tanaka.

“Maybe we should always take that strategy, beginning with a metropolis block, then a district, and finally we’ll synchronize the entire of Tokyo and past.”
