Hi Space forum, I am not an astro scientist or related, just some ordinary guy that love mystery hidden in our space. Pardon me if my question is too ordinary. I have too much question about space. 1. I once watched about gravity visualized video that said star bend space (visualized with a...

I have a question to ask people that know or understand a lot about the universe and mathematics. So the question is this: "If the reference point of light doesn't experience time due to time dilation at higher speeds, does this mean that time stops? If time would stop would this mean that...

Can it not be so that the dark matter we're looking for perhaps not even exist and the bindimg/repelling force might be space itself, since black holes collide and gravitational waves are generated, and the speed at which those waves travel can't surpass that of light, so it may be that those...

What is preventing us from sending numerous tiny probes/orbiters into interstellar space, do we still lack the technology or courage? Since through gravity assist alone we can increase the speed of spacecrafts, why don't we send out many in various directions, with all the necessary instruments...

Hello everyone, I'm currently a student in an Aeronautic School in Paris, France. I would like to know if one of you knows some stuff about Radio Isotopic Heater (RHU - Radioisotopic Heat Unit) to heat component during cold nights in space or lunar missions (mainly electronic components) and...

The clogging of near-Earth space could lead to the "Kessler effect" - a situation where space travel is not possible, as NASA experts warned earlier this year. Donald Kessler, an analyst at the National Aeronautics and Space Administration, predicted back in 1978 that space debris would...

Thanks

The Summer Workshop on Teaching Space (SWOTS) offers an intensive short-course on the fundamentals of space, introduces academics to new and innovative techniques to teach about space, and provides them with access to the network of scholars, high-level government officials, and private...

What makes you love space, the universe, and the ideas of other planets and life? I'll start off. I've always liked space since I was a kid and I had stickers of the solar system on my bedroom wall. Now, still basically a kid, I'm more obsessed with space than I've ever been. No matter what...

I’m a writer and currently writing a book that involves space travel to a potentially habitable planet. I’ve done lots of research of potentially habitable planets that we are already aware of and I am aware that scientists believe there to be billions of planets in the Milky Way alone. What...

SpaceX Launch from Isla Blanca It was amazing. I cried. The ground shook. People stared. What an amazing moment in my life.

If you had 2 earths, one original and the other hollow with a 1m thick crust but with identical mass and dimensions as our earth. Would you experience gravity identically on the outer surface of both? Also, what would you feel if you stood on the inside surface of the hollow earth? If you stood...

Greetings, First of all, I am not a scientist. Nor do I work in the scientific field...If this is something that bothers you, you can leave right now if you wish to have insights only from experts. However all I can say is that I think, analyze and read a lot about science, space, nuclear...

aerith.net says it could reach 2nd magnitude in July and Wikipedia says that it will reach perihelion on July 3rd and expected to be visible to the naked eye. Besides that and the theskylive.com page, I can't find anything else.

every celestial body, it is said, is part of a 2 or twin body system which revolve around a common centre of gravity, which sometimes lay inside one of the 2 such celestial bodies (because one is bigger than the other) so it looks as if the other is revolving around this ... is this theory...

Hi there! You're probably here because schools are closed in many places around the world right now. We're glad you came by. This forum is for student questions or projects. We'll help you find the answers you need to keep learning! Space.com is loaded with amazing facts and info on all sorts...

ExoMars (Exobiology on Mars) is an astrobiology program by the European Space Agency (ESA) and the Russian space agency Roscosmos. The goals of ExoMars are to search for signs of past life on Mars, investigate how the Martian water and geochemical environment vary, investigate atmospheric trace...

The human curiosity is one such element of the psyche that simply can never be quenched, especially when it comes to space travel. Did you know that the annual funding of the Earth Science program worldwide totals up to a meager $11.6 billion? Compare it with the budget of global space...
