How Big is the Present?

See more at http://www.spoonfedrelativity.com

An armchair physicist uses some basic Special Relativity facts and a choice of scale to acknowledge that the present is equal in size to the past and future combined. A pair of animated space-time diagrams from wikipedia are explained in some detail.

You can experiment with some of these ideas here:

A good video, fair explanation, but you may wish to write down your intended speech ahead of time so as to keep clarity to your audience, more so when dealing with topics that may be more than a little confusing.

@Nibenay3000 Trying to add more clarity, thanks. Check out my new website at spoonfedrelativity.  Exact link in video description.

events can come closer togethor but not the order of events. speed of light takes care of that.

garbage!!

If the forward direction of time that we feel is only one degree of arc within a full radius, then the other degrees would be alternative possable futures in keeping with Richard Dawkin's 'sum over historys' concept. how could we see alternative 'realitys' when we have no conceptualisation of what they could be?

with no concept how can we conceptualise? and by definition the 'un-seen' futures are beyond our capability to concieve.

the past and the future are human costructs, tools to make linear sence of non linear events within the sphere of one persons perspective.

the present is infinate and simoltaniously infinitesimal. the feeling of 'time passing' is simply a side efect of decay,entropy, the narrowing of possabilitys down to a single string of events.
