Reply to comment by Evening_Team in Will mankind ever travel outside our solar system? by savol_
A while ago someone somewhere somehow said something like E=Mc2. Let's say you believe this. Can you share some knowledge that in near future how is it might be possible for us to travel in the speed of light? Forget we're going outside of our solar system for a moment. Just how the traveling in light speed is possible. You can send AI or whatever you like to send.

Physically no. Not just no it's even impossible to travel that vast distance. Voyager spacecraft is nearly out of the solar system. But still not out completely from our solar system. It takes 23+ something hours to travel signals from/to Voyager and earth ( SPEED IN LIGHT-YEARS). so imagine what we've to achieve to travel in light speed.

Reply to Theoretically if we could instantly send a strong-enough telescope to a location millions of lightyears away from Earth, would we be able to see into our past? by Billy_bilo_
Keep everything aside and try to digest how vast our observable universe is. Even the word theoretically gets lost somewhere. Even information gets lost. Those lights we see from distant stars 🌟 we not sure if it's still there or not. Signals from voyager take just a little over 20 light hour to reach earth. Imagine the distance.
