Readers ask: When will andromeda collide?

What will happen when we collide with Andromeda?

When the Andromeda galaxy crashes into the Milky Way, this is what it could look like from Earth. The Milky Way is on track to collide and merge with its nearest neighbor, the Andromeda galaxy, in about 4 billion years. By then, the sun will have swollen past the orbit of Venus, charring Earth to a crisp.

Will humans survive Andromeda collision?

Assuming that human beings, or life, still exists on Earth at that time, they will have survived so much due to the ongoing death of the sun, that the gravitational pertubations due to the galactic collision will be nothing.

How many years will it take to get to the Andromeda Galaxy?

Andromeda is 2.54 Million ly away. That means when Alcubierre drive will be reality it will take 2.5 Million years to reach there. with current technology it takes around 20,000 years to travel 1 ly.

How fast is Andromeda moving towards us?

Based on Doppler shifting of its light, Andromeda is speeding toward us at 68 miles per second (110 kilometers per second). Compare this to the light from Andromeda, which is moving toward us at 186,000 miles per second (300,000 km/s ).

How old is the universe?

Our universe is 13.8 billion years old, a timescale much longer than the more relatable spans of hundreds or thousands of years that impact our lived experiences. So how do astronomers arrive at such an enormous number?

Is our galaxy moving?

The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference. The oldest stars in the Milky Way are nearly as old as the Universe itself and thus probably formed shortly after the Dark Ages of the Big Bang.

Will humans ever leave the Milky Way?

Our Galaxy, the Milky Way, is a disk of stars about 100,000 light-years across, and about 1,000 light-years thick. So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre.

How much bigger is Andromeda than the Milky Way?

The reason the collision is happening a few billion years ahead of schedule is that the Andromeda Galaxy is much bigger than it appears. The galaxy’s bright, starry disk is about 120,000 light years in diameter, making it slightly larger than the Milky Way.

How long will humans last?

We could easily survive another 250,000 years or, longer.

Will we ever visit Andromeda?

No way! Andromeda Galaxy is 2.4 millions light-years away from Earth. This means that even if you could travel at 1/10th of the speed of light (which would require a huge amount of energy, and a technology that we do not have), you would need about 240′000 years to get there!

Can we see Andromeda galaxy from India?

Answer: Yes, you can see a few other galaxies without using a telescope! The nearby Andromeda Galaxy, also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way ) spiral galaxy we can see with the naked eye.

Did Star Trek ever leave the Galaxy?

There is no Star Trek -esq galactic barrier. The only barrier to exiting the galaxy is the vast distance involved.

How long does it take for light from Andromeda to reach Earth?

Other Galaxies

Object Time for the Light to Reach Us
Sirius (brightest star in our sky) 9 years
Betelgeuse (bright star) 430 years
Orion Nebula 1500 years
Andromeda Galaxy 2.5 million years

What is the farthest galaxy from Earth?

“From previous studies, the galaxy GN-z11 seems to be the farthest detectable galaxy from us, at 13.4 billion light-years, or 134 nonillion kilometers (that’s 134 followed by 30 zeros),” Kashikawa said in a statement.

How long does it take to reach Andromeda at warp speed?

They work out that the 70,000 light year distance will take 70 years to complete. At that rate they are traveling 1,000 light years a year. The distance to the Andromeda Galaxy is 2.537 million light years. That means it would take 2,537 years to reach Andromeda.
