Why can't you be certain that the Andromeda galaxy exists today?

The basic premise is that the Andromeda Galaxy is 2.5 million light years away, so light from it takes 2.5 million years to reach it. Therefore we see it not as it is now but as it was 2.5 million years ago. The idea that it might no longer exist is rather absurd. A few million years may seem long to us but it is a very short time in terms of how galaxies evolve. It is in all likelihood impossible for a galaxy to experience any significant change in such a relatively short period of time.

What rocket will take you to Andromeda Galaxy?
None of them made today.
How far away is earth from the Andromeda galaxy in kilometers in scientific notation?
The Great Galaxy in Andromeda (also known as the Andromeda Galaxy or M31) is about 2.5 million light years from Earth. When we look at this galaxy today, we see light that has been traveling through space for 2.5 million years; i.e. when we look at the Andromeda Galaxy, we are seeing it as it was about 2.5 million years ago! Think about this, we are looking back in time.1 light year is the distance that light travels in 1 year. Speed of light is 300,000 kilometers/second, find the distance that light travels from the Andromeda Galaxy to Earth in kilometers and express it in scientific notation.
Your nearest neighbor galaxy?
The Andromeda galaxy is 2.6 million light years away.Thats 1.52840995 × 1019 miles away!That is, travelling at the speed of light, it would take YOU 2.6 million years to get there.
Why are there no photos of the whole of your galaxy?
Because we have never traveled outside of our galaxy in order to look back at it and take a picture of it. It will be a long time, if ever, before we ever have an actual picture of our galaxy seeing as we are about 23 light years away from the edge of the galaxy. If we left today and traveled 35,000 mph (the rate of the fastest object ever made by man, the Voyager probe) to the edge of the Milky Way galaxy, it would take around 456,400 years. So I wouldn't count on seeing a picture of our galaxy in our lifetime.
What would happen if the milky way exploded?
Then it would be "bye-bye" for us!(Just kidding!)Actual Answer:While individual stars in the Millky Way may go nova, it is unlikely that entire galaxy would explode. This type of massive galactic decomposition has not been observed in astronomy, although the M83 galaxy is sometimes described as an exploding galaxy. In this case the explosion is caused by super novas at the heart of the galaxy.On the brighter side, if the core stars of the Milky Way did go supernova and destroy the entire galaxy we wouldn't find out for 30,000 years. If it has happened and the "news" is still coming to us, it is too late to do anything.On the larger scale, if the Milky Way galaxy exploded the Universe would go on pretty much like it does today.

What is the diameter of the Universe today?
The radius of the observable Universe is thought to be about 46x10^9 Light Years.(And dark matter about which we know almost nothing, occupies perhaps 90% of it).Our Milky Way Galaxy is about 100 000 Light Years across, and out nearest neighbour, the Andromeda Galaxy is about 2.5 million light years distant.Answer2: My estimate of the diameter is about 320E24 meters.
Is galaxy pegasus good?
Yes, i like to think it's a great bey. i got my first bey today and it didnt let me down. It's a little hard to control for beginners but it's speed and strength are astounding. The only only letdown is the performance tip. It gives it CRAZY speed but you wont usually have enough energy left in the bey to make a powerful attack and to keep it going. None the less, i love it and its a great bey.
Does u.s.s.r still exists today?

Do soldiers really exist until today?
