[Past|Present|Future] Timetravel - Hoax?

[ErGingerbreadMandude]

I'd like to start this thread by reminding everyone that i debated over in my last thread that this is a thread i opened for a discussion to clear some of my doubts.

char *SMDLFR = "I don't have a strong mathematical background nor a science so if i made some dumb mistake please be polite and point it out";

Past | Present | Future -Hoax?

I Think we are all familiar with the concept of Past,Present and Future.

Past is what happened.
Present is what is happening.
Future is what is going to happen.

I think everyone would agree.(If you don't - please tell us why.)

So as i was awake during a silent night at around 1:30 am i came across this thought:

1 day(24 hrs) before the present time is the past.
1 hour(60 mins) before the present time is the past.
1 min(60 seconds) before the present time is the past.
1 second before the present time is the past.

So,wouldn't it be fair to say that:

1/10 second before the present time is the past.
1/100 second before the present time is the past.
1/1000 second before the present time is the past.
1/10000 second before the present time is the past.
1/100000 second before the present time is the past.

i.e. 1/infinity second before the present time is the past. (Reminder: SMDLFR)

So,i considered the number 1/infinity and i was like - wow what a small number its amazing because this frigging number is like infinitely small : 0.O)


So small that i thought perhaps this number would be negligible.(Reminder: SMDLFR)

So:
Negligible second before the present time is the past.

Wouldn't that make Past a non-existent idea?(Reminder: SMDLFR)

Similarly,
Wouldn't that make Future a non-existent idea?

And then i really freaked out:
Wouldn't that make Time traveling an impractical idea? And really smart scientists believe that the idea of time traveling is real.So it was obvious that my logic was faulty somewhere - i just don't know where - so i'm kind of scared.

Can someone please tell me why i'm wrong?
(I'm really not a math or science person and can very well be spitting out blunder so i hope you'd be cooperative.)

Other than that,i'd like a general discussion on the topic.

- Thank you for reading.
