The Logic of Time Travel

The probability that one or more people or others on earth now has a time travel device right now and knows how to use it is about 99.999%.

The logic goes something like this. "If any being in any galaxy or dimension has discovered time travel any time in the past, present or future, billions of years past or future then there is an extremely high probability that someone using time travel is here right now on earth!"

Because of this flawlessly logical premise MIT students had a party and sent out notices
several years ago inviting any actual time travelers. However, if you were a time traveler and you knew that time travel is potentially the single most dangerous thing that has ever been invented and know that one being could potentially eliminate the entire universe and all life anywhere anywhen I just don't believe you would have outed yourself at that party so no time travelers showed up.

However, this doesn't change anything. The logical probability that one or more humans or beings now on earth have one or more time travel devices that they can or do use is
about 99.999%. This is not to make you feel uncomfortable it is only to inform you of the likelihood.
