Many physics are of the opinion that the linear perception of time we have is an illusion. Does this mean the future and the past is here and now?

Does this mean the future is deterministic? Only we cannot see it?

Hi, I'm an Australian high school physics student currently studying the effects of high energy living upon the environment. As a physics student, I need to prove the steps I've made to reduce my household's carbon footprint with relevant physics equations/support. An example of this would be how reducing a hot water system's overall temperature would result in the saving of energy (q=mcT, reduce T to reduce q). Can anyone provide me with more examples pertaining to reducing household emissions?

in regards to a very large picture hanging on my wall it faces sunlight and I've just begun to get concerned if it's going to get discolored by UV rays. So much light bounces off and how much is absorbed?or does it reflect an equel amount of light as everything else like metal and such?

I cant think of one single thing that is affected by time ... can you? ........ for instance ..... does the passage of time age us? .... no .... our cells break down thats all ....... I believe time is merely a recording of events by humans ... but does not actually exist .... there is no "time" as such.
