Unraveling the Cosmic Mystery: Hubble Tension and Galactic Movement

Science Space Exploration

The universe is full of mysteries, from the movement of galaxies to the acceleration of expansion. Recent studies have delved into the Hubble tension and the movement of our own Milky Way galaxy, shedding light on some of these enigmas.

The Hubble Tension

⭐️Superclusters like Vena contain thousands of galaxies.

🌌The Hubble tension refers to the different acceleration of expansion in different parts of the universe.

🔭A recent study attempted to solve the mystery of the Hubble tension.

Galactic Movement

🕯️Distance candles are well-known objects that allow astronomers to measure distances in space.

🌠The Milky Way galaxy is moving towards the Centaurus constellation at approximately 600 km/s.

🌌Scientists studied Linea, an enormous structure containing 100,000 galaxies, to learn more about the movement of our galaxy.

FAQ

What is the Hubble tension?

The Hubble tension refers to the variation in the acceleration of expansion in different parts of the universe.

How do astronomers measure distances in space?

Astronomers use distance candles, well-known objects, to measure distances in space.

What is the speed of the Milky Way galaxy's movement?

The Milky Way is moving towards the Centaurus constellation at approximately 600 km/s.

What did the recent study on the Hubble tension confirm?

The study confirmed a bias of about 2 to 3%, making the Hubble tension slightly smaller than it actually is.

What did the study on Linea reveal about the movement of our galaxy?

The study on Linea revealed insights into the movement of our galaxy by studying an enormous structure containing 100,000 galaxies.

Summary with Timestamps

🌌 0:16The video discusses superclusters, including the one our galaxy is located in, and a recent study on the Hubble tension.

🌌 3:32Astronomers use distance candles to measure the distance to objects in space, but they assume that everything is stationary, which is not true as the Milky Way galaxy is moving in a certain direction.
