Starship Asterisk*

Now that is a very good question. though i am 14, maybe i can help you. Now, to have gravity, you first need a mass. Now photons, light particles, have a still mass of 0, then that does mean it would have a gravitational pull. hope it helps

Hi. I am 14, and i have a constant "thurst" for astronomy. MY first question would be... We know the andromeda galaxy has a red doppler shift, but do we know when/if it will ever collide with the milky way? i know its wayyyyyy beyond our lifetime, but i would like to know if it is possible

Though i am only 14, i feel that i can contribute reasonable information. My guess would be that it was a burst of natural gas being secreted from the volcano that got ignited by the magma's intense heat
