Aliens See Dinosaurs, Not Humans - Feynman's Scary Proof

Описание: #Relativity #SpaceTime #Physics
Do you believe the past is gone and the future hasn’t happened yet?
Do you assume that “now” is the same everywhere in the universe?

It isn’t.

If you were 65 million light-years away in the Virgo Cluster, aiming a powerful telescope at Earth, you wouldn’t see cities or airplanes. You’d see dinosaurs roaming prehistoric landscapes. So who is experiencing the “real” present? The answer will overturn your everyday intuition about time.

On Think About Physics, we explore a mind-bending idea inspired by Richard Feynman’s approach to explaining space-time: the universe may not be a 3-D world that evolves moment by moment, but a 4-D “block” where every event—past, present, and future—coexists.

We break down the Simultaneity Paradox: why two observers moving at different speeds can disagree about what events are happening “right now,” and why both perspectives are mathematically valid.

Here’s one way to picture it:

Imagine the universe as a giant loaf.
Slice it straight across—that slice is your “now.”
But start moving, and the slice tilts. Your new “now” cuts through events that someone else would label as the distant past… or the far future. The present isn’t universal. It depends on how you move through space.

What does that imply?

It points toward the “Block Universe” concept: the cosmic film may already exist in full. We are not creating frames—we are moving through them. The past isn’t erased. It’s simply located elsewhere in space-time.
