Black Holes

what happens when you travel inside a black hole

Lets Talk Black Holes

In the new movie Interstellar, Matthew McConaughey drives head first into a black hole. Although the special effects team made one of the most scientifically accurate depictions of what its like going into a black hole, you didnt get any actual visuals of what Matthew was seeing first-hand. And that is exactly what we'll be talking about today.

The closest black hole to earth is called V4641 Sgr, named after the stars that orbit it. Sense black holes are invisible, scientists normally find them by the dust and stars around them. Even though this big fella is the closest one to Earth, you have nothing to worry about. V4641 is between 1,600 and 24,000 light years away. Located somewhere in the constellation Sagittarius.

V4641 is a perfect example of a small black hole. Its two to three times more massive than our sun, and all that mass is confined into a space of less than 4 miles in diameter. The center is extremely dense and therefor has a colossal gravitational pull, which means its strong enough to suck in and trap anything that comes near it.

But what happens when you go inside of it?

As you travel near the black hole, you'll see blackness blotting out light from different stars around you. Black holes distort the space around them, which bends the way you see light traveling. You'll be seeing something like this:
The outer ring is a result of gravitational lensing, which is where gravity bends light and distorts and/or magnifies what we see. anything with a strong gravitational pull can create this, including galaxies and galaxy clusters. The edge of a black hole, outlining the circle in the gif above, is called the event horizon. Its the edge of the door, the point of no return. once you go in, you're not coming back.

Once you pass the horizon line, an amazing action takes place. Every molecule and atom in your body stretches out, causing what is known as spaghettification. Here's what spaghettification looks like with a space craft:

Eventually, you'll be stretched out atom by atom, and it doesnt take a rocket scientist (no pun intended) to tell you that its one of the most unpleasant way to die. A smaller black hole takes a shorter amount of time to kill you, much like the one closest to us. Approximately 25,000 light years from Earth, at the center of our galaxy, there is thought to be a supermassive black hole that is 4.3 million times more massive than our sun. But, if you travel the distance to this larger black hole, you'll get close to the event horizon, and even pass it while still alive and coherent. Here's what it should look like:
You can get closer to a larger black hole because the event horizon is pushed farther back, so you get this killer view. The tidal forces at the event horizon are weaker, if the moon was farther away from earth, we would have smaller tides. Therefore, you wont turn into super unsatisfying spaghetti until you actually enter the black hole. As you fell closer toward the event horizon, the gravitational force around you would grow. This means it would bend the light that reached your eyes more strongly, which is what you're seeing in the animation above. Moreover, time would tick more slowly the deeper you fell into the black hole. From your perspective, time would tick on as usual, but from an outsider's perspective, like someone on Earth, you would age very slowly. This phenomenon is called gravitational time dilation.

As you fall closer to the event horizon, the blackness will cover your entire field of vision, then you know you're officially in the black hole. The last chance to see the universe is gone, and you'll never see the light of day again. Afterwords, gravity will pull you in and you'll begin to be speghettified.

No one knows what happens beyond this point, and astrophysicists suspect that the physics we use on earth breaks down inside of the black hole. After you exit the universe, We wont know what happens.
