What Is a Wormhole Exactly?
A wormhole is a hypothetical spacetime pathway through spacetime that can connect two distant points in the universe.
Here’s an easy way to look at it:
- Picture spacetime as a flat piece of paper.
- You want the flat piece of paper to go from Point A to Point B.
- Usually, you would travel across the piece of paper.
But, if you fold the paper in half so that Point A and Point B touch, you can jump across, that would be a wormhole!
But here’s the real catch: Wormholes would most likely collapse immediately, unless it was held open by something called negative energy, which we have explored as of yet!

Can Wormholes Be Used for Time Travel?
This is where things get super crazy! Some physicists believe that if one of a wormhole moves almost at the speed of light, time would slow down for that end due to time dilation. This would mean if a traveler that was entering one end might come out the other end at an earlier time, pretty much travelling back in time.

Is It Possible to Time Travel?
Time travel actually happens! Astronauts on fast-moving spaceships often experience time more slowly than us on Earth!
We’ve tested time travel using atomic clocks in aircrafts.
⏱️ This is expected to relativity when time moves slower the faster you go.
Can You Travel To The Past?
The challenge? Paradoxes.
Example: What would happen if you went back in time to stop your grandma and grandpa from meeting each other? Scientists called this the Grandfather Paradox, it’s one of the reasons backwards time travel remains undetermined.
What I Learned This Week:
This week has shown me that wormholes and time travel aren’t just cinematic artistry, they come from real physics!
Just because something is numerically feasible doesn’t mean it does exist in real life!
The websites and the video made these ideas feel more understandable, and even more fun to learn about! I’m starting to think sci-fi might be closer to science than I really thought!
Questions To Wonder About:
- If wormholes were real and stable where would you travel?
If you were able to send a message to the future or past through a wormhole, what would you say?
