there is no scientific evidence or widely accepted theory supporting the existence or feasibility of a laser time machine, as described in the context of Ron Mallett's claims. It is important to note that time travel, especially into the past, is a topic that remains largely speculative and theoretical in the field of physics.
While there have been theoretical proposals and discussions about the possibility of time travel, such as the concept of wormholes or the manipulation of spacetime, they are highly speculative and require technologies and understanding beyond our current capabilities.
Without specific details on the exact nature and principles of Ron Mallett's claimed laser time machine, it is not possible to assess the potential for future modifications or its ability to send information back more than 10 years.
It's worth mentioning that claims of time travel inventions or breakthroughs often arise in popular culture and pseudoscientific contexts, so it's important to approach such claims with skepticism and rely on scientific consensus and rigorous evidence.
