Does Information Have Mass? An Experimental Physicist Weighs In

Physicist Melvin Vopson argues that information has mass; Eric Holloway replies that, if so, it must come from outside the universe. Meanwhile…

It’s generally held that information does not have mass. However, physicist Melvin Vopson, reflecting on the work of Rolf Landauer (1927–1999), offers a somewhat alarming view: Not only does information have mass but that — at the rate we humans output it now — its energy will outweigh Earth. Yesterday, Eric Holloway offered a response to that claim: Let’s accept that creation of information can indeed increase the amount of energy and mass in a system. But, according to the conservation of energy, the energy in a closed system remains constant. So, if Vopson is correct we now have a mystery because his theory is in tension with the conservation of energy. The only solution is that the system is…

Does Information Weigh Something After All? What If It Does?

At the rate we create information today, one physicist computes that in 350 years, the energy will outweigh the atoms of Earth

In the 1960s, IBM researcher Rolf Landauer (1927–1999) observed that if the logical information in a computational system decreased, then the physical entropy in the system must increase (Landauer’s Principle). This conclusion follows from the principle that the entropy in a closed system can never decrease. A decrease in the logical information corresponds to a decrease in entropy. And factoring in the principle that the entropy cannot actually decrease, the physical system itself must increase in entropy when the information decreases. This increase in entropy will result in the emission of heat, and a reduction of energy in the system. Now Melvin Vopson, a physicist at the University of Portsmouth, has taken Landauer’s principle to the next logical step. He…

Could Information Be — at Long Last — the Missing Dark Matter?

Materialist thinkers may need to see information as material, whether that approach fits information or not

There is no evidence that information is dark matter or that consciousness is physical but materialists understandably long for evidence that would make their theory more viable.
