Does the past still exist?

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.

Can we still go back in time?

There are known to be solutions to the equations of general relativity that describe spacetimes which contain closed timelike curves, such as Gödel spacetime, but the physical plausibility of these solutions is uncertain. Many in the scientific community believe that backward time travel is highly unlikely.

How far back can a person remember?

Adults can generally recall events from 3–4 years old, with those that have primarily experiential memories beginning around 4.7 years old. Adults who experienced traumatic or abusive early childhoods report a longer period of childhood amnesia, ending around 5–7 years old.

Is deleting memories possible?

Memory erasure has been shown to be possible in some experimental conditions; some of the techniques currently being investigated are: drug-induced amnesia, selective memory suppression, destruction of neurons, interruption of memory, reconsolidation, and the disruption of specific molecular mechanisms.

Why can't we remember being a baby?

Our brain is not fully developed when we are born—it continues to grow and change during this important period of our lives. And, as our brain develops, so does our memory.

Is it possible to remember being born?

It is generally accepted that no-one can recall their birth.
