What if speed of light was Faster? Would TIME travel be prohibited?

A recent post of slower than normal speed of light brought to mind "what If" light speed was faster. C being a constant, if it increased say by 10x, would the sun output be a 100 fold increase?
Also, it makes me question TIME travel. If one were to travel into the future, would there be a relationship to the speed of TIME (in this supposition, faster than normal speed of light), thereby causing the TIME traveler to incinerate?

Would time speed up if light did? I don't think so but it might seem that way. The light year would be longer, and the basic length of a four-vector in SR (squared) is $$c^2t^2 - x^2 - y^2 - z^2$$, so the time component of any force or momentum would be greater. I haven't thought enough to see all the implications. Think about $$e = mc^2$$!

If the speed of light were faster, it would have significant effects on our understanding of the universe and the laws of physics. It is impossible to say for certain what the consequences would be, but it is likely that the sun's output would increase significantly. However, it is important to note that the speed of light is not directly related to the sun's output. The sun's energy output is determined by its mass and composition, not the speed of light.

As for time travel, it is a highly speculative concept and there is no scientific evidence to support its possibility. The idea of traveling faster than the speed of light, whether it is in the past or the future, remains purely hypothetical. Additionally, even if the speed of light were faster, it is unlikely that it would have any effect on the concept of time travel. Time is a fundamental dimension in our universe and it is not dependent on the speed of light.

In regards to the concern about incineration, it is important to understand that the speed of light is not a measure of temperature. The speed of light is a fundamental constant that is related to the fabric of space-time, not temperature. Therefore, even if the speed of light were faster, it would not necessarily result in a higher temperature or incineration for a time traveler.

In conclusion, while it is interesting to speculate about the effects of a faster speed of light, it is important to remember that it is purely theoretical and has no basis in scientific fact. Time travel, in any form, remains a subject of science fiction and is not supported by current scientific understanding.
